“How do I look?” Catherine turned around while fastening her diamond earrings, trying to get ready before Elliot Burch’s car arrived.

Vincent stepped toward her. “You look beautiful.”

With a big smile, Catherine stepped into his arms, wrapping them around his waist and placing a kiss on his chest. “Thank you. I shouldn’t be much later than midnight. I told Elliot I was going to turn into a pumpkin at that time, and he promised to have me out the door by then.” Smiling, she stepped back and looked into his eyes. “I can’t wait until tomorrow. It will be nice to spend uninterrupted time together, even with two chaperones. Did you pack everything we need?”

“Yes. Mouse made sure we didn’t forget the new pick he found for you, and William said he would have all the supplies ready. You have nothing to worry about.” Vincent placed a kiss on her forehead, careful not to disturb her hair or makeup. “We should be on our way by nine.”

“I’m sure the car’s outside.” Catherine planted a kiss on his mouth. “I’ll see you soon. Love you.”

Nothing made her happier than these intimate touches. For the last year, she had been filling his days with them—caresses, pets, kisses—trying to get away with as much as she could. Father once commented that he rarely saw them not touching, even in the smallest way. After nearly three years of denying themselves anything beyond a hug or a kiss on the cheek, Catherine had done her best to make up for lost time. Vincent was not complaining.

“Do you think Jamie and Mouse will mind sharing quarters with us sometimes?” she asked while grabbing her clutch.

“Jamie said Mouse was very excited to spend time with his two favorite people.” Vincent held her coat out and helped her into it. “I don’t think you have anything to concern yourself with.”

Catherine smiled, squeezed his hand, and gave him one last kiss before walking out the door of their brownstone.

* * *

The ballroom of the Plaza Hotel glittered with crystal chandeliers and the soft murmur of New York’s elite. Catherine stood near the edge of the crowd, champagne flute in hand, watching Elliot accept yet another handshake from a city councilman. His smile was genuine tonight – not the calculated expression he’d worn in his more ruthless days, but something warmer, more at peace.

When he finally broke away and made his way toward her, Catherine raised her glass. “Congratulations. This is well-deserved, Elliot.”

“Coming from you, that means something.” He touched his glass to hers, his eyes reflecting a depth of gratitude that went beyond the evening’s accolades. “Thank you for being here, Cathy. I know you and Vincent have an early start tomorrow.”

“We wouldn’t have missed this. Vincent sends his congratulations, too. He’s proud of what you’ve accomplished – we both are.” Catherine’s voice was soft but sincere. “You’ve changed so many lives with this project.”

Elliot’s expression flickered with something vulnerable. “I had good teachers. You showed me there was more to life than building empires.” He paused, then added quietly, “How is he?”

“He’s wonderful. Happy.” Catherine’s face lit up in a way that needed no further explanation.

“Good. That’s… that’s good.” Elliot smiled, and this time it reached his eyes. “You both deserve that happiness.”

Catherine squeezed his arm gently. “So do you, Elliot. And you’re finding it—I can see that.”

The clock on the far wall showed 11:50. Catherine glanced at it and laughed. “My carriage awaits before I turn into a pumpkin.”

Elliot walked her to the entrance where the limo idled at the curb. “Safe travels tomorrow. And Cathy?” He kissed her cheek. “Thank you. For everything.”

“Take care of yourself, Elliot.” Catherine slipped into the car, her heart full. As the limo pulled away from the glittering hotel, she settled back against the seat, already imagining Vincent waiting for her at home – their last quiet night together before the adventure began.

* * *

Mouse paced back and forth in the chamber he shared with Jamie, checking his pack for the third time that morning. “Picks – good, good. Rope. Lanterns. Extra candles. Cloth bags for –” He patted his vest pocket nervously, feeling the small leather pouch hidden there.

“Mouse, we’ve checked everything twice already.” Jamie looked up from rolling her sleeping bag, amusement dancing in her eyes. “What’s got you so wound up? It’s just a mining trip.”

“Not just mining! Crystal cavern – very special. Catherine’s never seen it. Vincent wants to explore. Important trip. Very important.” Mouse’s words tumbled out faster than usual.

Jamie stood and placed a hand on his shoulder. “Hey. It’s going to be great. A whole week exploring together – what could be better than that?”

Mouse’s expression softened. “Nothing. Nothing better.” He caught her hand and squeezed it, then quickly busied himself with his pack again before she could see the flush creeping up his neck.

An hour later, they met Vincent and Catherine in William’s kitchen. The cook had laid out an impressive array of supplies on the long wooden table – dried fruits, jerky, fresh bread, cheese wheels, and containers of stew that would keep for days.

“William, you’ve outdone yourself,” Catherine said, surveying the provisions with wide eyes.

“Can’t have you starving out there. The crystal cavern’s a good two days’ journey.” William handed Vincent a carefully wrapped package. “Extra tea and coffee. I know how you two get without it.”

Vincent eyed Catherine and accepted it with a slight smile. “Your thoughtfulness is appreciated.”

“I’m so excited!” Catherine bounced slightly on her toes. “After all these years of hearing about the crystal cavern, I finally get to see it.”

“It’s beautiful,” Mouse said, shouldering his pack. “The way the light catches the formations – Nothing like it.”

“We should be able to do some exploring. I haven’t mapped much past the cavern,” Vincent added, his voice taking on a more practical tone. “Father’s been wanting to identify potential retreat locations. Somewhere the community could go for respite, away from the main hub.”

Mouse nodded vigorously. “Many tunnels. Many caverns. Good exploring. Very good.” His hand drifted to his vest pocket again.

Jamie caught the gesture but misread it. “Did you remember your lucky compass?”

“Yes! Yes, have compass. Have everything.” Mouse grinned, relief flooding through him. She suspected nothing.

Vincent caught Mouse’s eye and gave him an almost imperceptible nod of encouragement. Catherine had confided the plan to him, and he’d been quietly supportive.

“Well then,” Catherine said, linking her arm through Vincent’s. “Shall we begin our adventure?”

The four friends gathered their supplies and headed toward the deeper tunnels, their voices echoing with laughter and anticipation. Mouse walked beside Jamie, his heart hammering with a mixture of excitement and terror. Somewhere in those crystal caverns, an item would help him tie himself indefinitely to the woman he loved with all of his heart.

* * *

By the time they reached the halfway point, Catherine’s feet were protesting, and even Vincent’s steady pace had slowed. They found a wide chamber with smooth stone walls and settled gratefully onto the ground, unpacking William’s provisions.

“I think my legs are going to fall off,” Catherine groaned, stretching out beside Vincent.

Jamie laughed, pulling out the wrapped bread. “Wait until the way back. That’s when it really hits you.”

Mouse immediately busied himself arranging their meal, laying out cheese and dried fruit with careful precision. “Good food. William knows. Very good.” He settled beside Jamie, close enough that their shoulders nearly touched, and handed her a piece of cheese. She took it with an easy smile, their fingers brushing naturally.

Catherine caught the exchange and smiled, leaning into Vincent’s side. He wrapped an arm around her shoulders, and she tilted her head to rest against him. “This is perfect,” she murmured. “All of us together like this.”

“Catherine gets mushy when she’s tired,” Jamie teased, though her eyes were warm.

“Guilty.” Catherine reached up to trace her fingers along Vincent’s jaw. “But can you blame me? How often do we get to do something like this?”

Vincent turned his head to press a kiss to her palm, his eyes soft with affection. “Not often enough.”

Mouse leaned back against the stone wall, and Jamie naturally settled against his shoulder, her head tilting to rest there. It was an unconscious gesture, the kind that came from months of sharing a chamber, of knowing exactly how to fit together. Mouse’s arm came around her waist, comfortable and easy, and she reached over to steal a piece of cheese from his portion, earning a mock-offended look that made her laugh.

“Hey! That’s mine,” he protested, but he was already offering her more.

“Sharing is caring,” Jamie said primly, then nudged him with her elbow. “Besides, you always make yours bigger anyway.”

They ate and talked, sharing stories about the tunnel community. Mouse recounted one of his latest inventions that had gone spectacularly wrong, sending Father into a sputtering lecture that lasted an hour. Jamie described Cullen’s latest carpentry mishap, and Catherine nearly choked on her water laughing.

As darkness settled more deeply around them, they prepared for sleep. Vincent and Catherine spread their bedroll on one side of the small fire they’d built, while Jamie and Mouse laid theirs on the opposite side.

As Mouse told a story, Jamie occasionally interjected with corrections or added details, their rhythm easy and practiced. When Mouse got animated about a particular part, he gestured widely, and Jamie steadied him with a hand on his arm, used to his enthusiastic movements. He squeezed her hand briefly in thanks before continuing.

Catherine curled into Vincent’s arms, her back against his chest, his warmth surrounding her. Across the fire, Jamie and Mouse settled onto their bedroll with the ease of habit. Jamie lay on her side, and Mouse curved around her from behind, his arm draped across her waist, her back against his chest – a mirror of Vincent and Catherine’s position. Jamie reached back to squeeze his hand gently, and he pressed a soft kiss to the back of her neck before they both settled into sleep.

Catherine smiled into the darkness at the symmetry of it and closed her eyes.

* * *

By midday the next day, they reached the crystal cavern, and Catherine stopped dead in her tracks.

“Oh my God,” she breathed.

The cavern stretched before them like something from a dream. Crystals of every size jutted from the walls and ceiling, catching the light from their lanterns and throwing it back in a thousand rainbow fragments. Some formations were as tall as Vincent, others as delicate as icicles. The air itself seemed to shimmer.

“It’s…” Catherine couldn’t find words. She turned to Vincent, her eyes shining. “It’s the most beautiful thing I’ve ever seen.”

“I thought you might like it.” Vincent’s voice was warm with pleasure at her reaction.

Mouse was already moving deeper into the cavern, his practiced eye scanning the formations. “Good crystals here. Very good. Jamie—look, jewels!” He pointed to a cluster of deep red stones embedded in the wall.

Jamie moved closer, her breath catching. “Rubies?” She reached out tentatively to touch one, and the light caught it, making it glow like captured fire. “Mouse, they’re gorgeous.”

“You like?” Mouse’s voice was eager, almost anxious.

“I love them. They’re perfect.” Jamie’s smile was radiant, and Mouse’s whole face lit up in response.

They spent the next few hours carefully mining, using Mouse’s tools to extract the precious stones without damaging them. Catherine worked alongside Vincent, learning the technique, while Mouse guided Jamie to the best specimens.

Vincent paused for a moment, pointing at a green stone that caught the light. “Catherine, look, an emerald. The exact color of your eyes.”

Catherine’s breath hitched. “Vincent, it’s beautiful.”

Without Catherine noticing, he tucked it carefully into his pouch.

Mouse had been watching, and he caught Jamie’s eye, gesturing to the rubies she’d admired. She smiled at him – really smiled – her expression light with excitement and wonder.

By the time they finished, their bags held a respectable collection: stones for Mouse’s ring, and enough to trade for winter supplies for the community. Mouse kept touching his vest pocket, as if reassuring himself that his plan was still intact.

“Successful day,” Vincent observed, helping Catherine to her feet.

“Very successful,” Mouse agreed, grinning.

They gathered their things and headed toward the tunnel that would lead them back, tired but satisfied.

That’s when Catherine saw it.

“Wait – is that a bird?”

A flash of white swooped through the higher reaches of the tunnel ahead, wings beating frantically against the stone ceiling.

“A dove?” Jamie stepped forward, craning her neck. “How did it get down here?”

The bird circled, clearly disoriented, then flew deeper into the tunnel system.

“Poor thing must be terrified,” Catherine said. “Should we try to help it?”

Vincent studied the direction it had flown. “That tunnel branches off from our route. I don’t recognize it.”

“We follow?” Mouse asked, already moving forward. “Carefully. Not scare it more.”

They pursued the dove through winding passages, keeping their distance, following the flutter of white wings and the soft coo of distress. The tunnel sloped gradually downward, and the air grew warmer.

After nearly a mile, the tunnel opened up.

Catherine gasped.

They stood at the entrance to an enormous cavern – easily three times the size of the crystal chamber. But it wasn’t the size that stole her breath. In the center lay a pool of water, its surface perfectly still and reflecting streams of light that seemed to come from nowhere and everywhere at once. The light danced across the water in shifting patterns, warm and golden, as if the sun itself had found a way into the depths of the earth.

The dove had settled on a rock formation near the pool, preening its feathers, finally calm.

“How is there light?” Jamie whispered, as if speaking too loudly might break the spell.

Vincent moved to the edge of the pool, studying the cavern walls. “It must be reflected. Perhaps through quartz formations in the rock above, bouncing the light down through layers of stone.” He shook his head slowly. “I’ve never seen anything like this.”

Mouse dipped his hand in the water and jerked back in surprise. “Warm! Water is warm!”

Catherine knelt beside the pool, trailing her fingers through it. The water was almost bath-temperature, heated by some underground thermal source. “This is incredible.”

“We camp here,” Mouse declared. “Best place. Very best place.”

No one argued.

They set up camp near the pool’s edge, and as evening settled over them – though time felt strange in this lit cavern – they couldn’t resist the water’s call. Catherine and Jamie changed behind a rock formation while Vincent and Mouse did the same, and soon all four were in the pool, the warm water easing their tired muscles.

“Remember when Father tried to organize the children’s choir?” Jamie said, floating on her back. “And Mouse’s ‘improvements’ to the pipe system created that echo that made everyone sound like they were singing underwater?”

Mouse looked sheepish. “Was trying to help.”

“Father’s face turned purple,” Vincent added, the corner of his mouth quirking up. “I believe his exact words were, ‘Mouse, you have created an acoustic abomination.'”

Catherine burst out laughing, the sound echoing beautifully off the cavern walls. “Please tell me someone stopped him before he ‘fixed’ it again.”

“Pascal hid all his tools for a week,” Jamie said, grinning. “Mouse sulked in his chamber and wouldn’t come out until William bribed him with chocolate cake.”

“Was good cake,” Mouse said defensively, but he was smiling.

They floated and talked, sharing story after story – Pascal’s romantic disasters, Cullen’s terrible singing. Father’s attempt at making breakfast for the community when William was sick with the flu. Catherine and Jamie laughed until their sides hurt, and even Vincent’s rare, warm chuckle joined in.

Mouse floated closer to Jamie, reaching for her hand beneath the water with easy confidence. She took it without hesitation, their fingers intertwining naturally. He pulled her gently toward him, and she came willingly, settling against his side in the warm water. Above them, the mysterious light continued its dance across the water’s surface, and the white dove cooed softly from its perch.

* * *

Morning came – or what they assumed was morning in the timeless depths – and as they packed their things, Mouse pointed to the far left side of the cavern.

“Passage there. Continues.”

Vincent moved closer to investigate, Catherine at his side. The tunnel mouth was wide and smooth, worn by water over countless years. A faint breeze drifted from its depths, carrying something different – a hint of moisture heavier than the cavern air.

“Should we?” Catherine asked, her hand finding Vincent’s.

He studied the passage, then looked back at their supplies. “We have enough provisions for several more days. And I’ve never mapped this section.” His voice held a note of curiosity that made Catherine smile.

“Adventure, then,” she said.

Jamie and Mouse quickly agreed, and they set off into the unknown passage, the white dove launching from its perch to follow at a distance, as if it had appointed itself their guide.

The tunnel sloped gently downward at first, then leveled out. As they walked, Catherine noticed the air changing – growing thicker, damper. It clung to her skin like a second layer.

“Is it just me, or is it getting more humid?” Jamie asked, pushing her hair back from her forehead.

“Not just you,” Vincent confirmed. “We’re approaching something. A larger water source, perhaps.”

Mouse ran his hand along the tunnel wall. “Walls wet. Very wet. Different than before.”

They pressed on, and after what felt like hours, the passage opened into a smaller chamber. Catherine’s lantern light caught something that made her stop.

“Look at that.”

Embedded in the wall was a massive fossil – the skeletal impression of some ancient sea creature, its spine curved gracefully through the stone, ribs spreading like the fingers of a hand. It was easily ten feet long, perfectly preserved.

“It’s beautiful,” Jamie breathed, moving closer. “What was it?”

Vincent studied it with quiet wonder. “Some kind of marine reptile. Millions of years old. This entire area must have been underwater once.”

Catherine reached out to trace the delicate bone structure with her fingertips. “It’s like finding a ghost,” she murmured. “Something that lived and died so long ago, and here it is, waiting all this time to be seen.”

Vincent’s hand covered hers against the stone. “Some things endure,” he said softly, his eyes on her face rather than the fossil.

“Some things are worth the wait.” She turned to him, her breath catching at the tenderness in his expression, and rose on her toes to kiss him gently.

Mouse cleared his throat. “Should keep going. Dove is waiting.”

Indeed, the white bird had perched on a rock formation ahead, cooing impatiently.

They continued, and the humidity grew more pronounced with each step. Catherine’s shirt clung to her back, and she could taste salt in the air – faint but unmistakable.

“Do you smell that?” she asked Vincent.

“Brine,” he confirmed. “We’re close to something.”

The passage narrowed, then opened again, and suddenly they heard it – the soft gurgle of running water. They emerged into a wider tunnel where a stream cut across their path, flowing from right to left, its surface dark and swift.

Vincent knelt at the edge and cupped his hand, bringing the water to his lips. He tasted it carefully, then looked up at Catherine with surprise in his eyes.

“It’s salt water. Not pure ocean water, but saltier than it should be this far inland.” He stood, studying the stream’s flow. “The ocean must be feeding this somehow. We’re closer to the surface than I thought.”

“How close?” Catherine asked, excitement building in her chest.

“I don’t know. But close enough that seawater is finding its way through the rock.” He looked at the passage ahead, then back at their group. “We have provisions. If you’re willing, I’d like to continue.”

“Yes,” Catherine said immediately. Jamie and Mouse nodded their agreement.

They followed the stream, sometimes walking beside it, sometimes crossing it where the tunnel demanded. The white dove flew ahead, always just within sight, leading them onward.

After another hour, Vincent paused, his head tilting slightly.

“What is it?” Catherine asked.

“We’ve been climbing,” he said slowly. “For the last two hours, perhaps more. The incline is so gradual I almost didn’t notice, but we’re definitely ascending.”

Catherine looked back the way they’d come and realized he was right. The tunnel had been rising steadily, drawing them upward toward – what? She hardly dared to hope.

The passage grew steeper, and they had to use their hands in places to pull themselves up over smooth stone. The dove disappeared around a bend ahead, and when they rounded it themselves, they found a cluster of massive boulders blocking their path.

“Dead end?” Jamie asked, disappointed.

But Mouse was already scrambling up the rocks. “No – look! Opening! There’s opening!”

They climbed after him, squeezing between the boulders, and suddenly –

Light.

Real light. Sunlight.

Catherine emerged first after Mouse, blinking against the brightness, and her breath left her in a rush. They stood in an open cavern, but it wasn’t enclosed – the far side opened completely to the sky. Beyond the rocky opening lay a small sandy cove, protected by towering rock formations that curved around it like sheltering arms. And beyond that, sparkling in the afternoon sun, was water. A vast body of water that could only be the Hudson River.

She turned back to help Vincent through the opening, and when he emerged, when he lifted his head and saw the sky –

Catherine’s heart broke and mended in the same instant.

Vincent stood frozen, his face tilted upward, his eyes closed. The sun poured down on him, warming his skin, and she watched a transformation happen. He’d felt sunlight before – through the brownstone windows, in their backyard when the privacy fence and trees shielded them from view – but never like this. Never with such absolute freedom. Never able to simply exist in full daylight without fear, without the constant vigilance of hiding.

The tension he always carried, the careful guardedness, melted away. His shoulders dropped. His breathing deepened. And when he opened his eyes, they were bright with something that looked like joy and grief and wonder all tangled together.

“Vincent,” Catherine whispered, moving to his side.

He didn’t speak. He just reached for her, pulling her close, and she wrapped her arms around him as he stood there, face turned to the sun, holding her as if she were the only thing anchoring him to the earth.

“How long has it been?” she asked softly. “Since you could just… be? Like this?”

“Never,” he managed. “Outside, never like this.”

Catherine’s eyes stung with tears. She’d known – how much he sacrificed by living below. How much he gave up. Not just sunlight, but the simple, basic freedom to exist openly in daylight, something she took for granted every single day.

“I’m so happy you’re here,” she said, her voice thick. “I’m so happy you can feel this.”

He looked down at her then, and the expression on his face was so open, so vulnerable, that she had to rise up and kiss him. He kissed her back with a fierce tenderness, one hand cradling her face, the other pressed against the small of her back.

When they finally broke apart, Mouse and Jamie had already made their way down to the sandy cove. The dove had settled on one of the rock formations, preening contentedly in the sun.

“Come on,” Catherine said, taking Vincent’s hand. “Let’s explore. I always dreamt of being able to walk with you on the beach.”

They climbed down to the sand, and Catherine immediately understood why this place had remained hidden. The rock formations curved around the cove in such a way that it was invisible from the water unless you knew exactly where to look. It was a secret pocket of beach, protected and private.

In the distance, a fishing boat drifted lazily across the river, its occupants too far away to notice the small group on the hidden shore.

“Vincent,” Mouse called, “never been here? In all your exploring?”

Vincent shook his head slowly, still looking around in wonder. “Never. I had no idea this existed.”

“It’s perfect,” Jamie said, dropping their packs in the sand. “Can we stay? Just for today?”

“And tonight,” Catherine added, squeezing Vincent’s hand. “Please. Let’s stay.”

Vincent looked at her, then at the sun, then back at her. “Yes,” he said simply. “Yes.”

They spent the afternoon in a kind of blissful suspension of reality. Mouse and Jamie explored the rock formations, finding tide pools full of small crabs and starfish. Catherine and Vincent walked along the water’s edge, their feet in the surf, their hands intertwined.

“I never want to leave,” Vincent said quietly, watching the light dance on the water.

“Then we won’t,” Catherine said. “Not yet. We’ll stay as long as you want, and we will come back. Just you and me,” her words full of promises and meaning.

He stopped walking and turned to her, the wind catching his hair. “Catherine, I –” He paused, searching for words. “You’ve given me so much. More than I ever thought I could have. But this –” He gestured to the sun, the sky, the open air. “Sharing this with you –”

“I know,” she said, reaching up to touch his face. “I know, Vincent.”

He pulled her close, and they stood there in the surf, the water lapping at their ankles, the sun warm on their shoulders. Catherine rested her head against his chest and listened to his heartbeat, steady and strong.

“I love you,” she whispered.

“And I love you,” he replied, his voice rough with emotion. “More than words can say.”

As evening approached, they built a fire on the sand – a real fire, with driftwood Mouse collected, not the careful, contained fires of the tunnels. They cooked some of William’s provisions and ate while watching the sun sink toward the horizon, painting the sky in shades of orange, pink, and gold.

Catherine sat between Vincent’s legs, her back against his chest, his arms wrapped around her. Jamie and Mouse sat close together on the other side of the fire, Mouse’s arm around Jamie’s shoulders. She leaned into him comfortably, watching the sunset.

“Best trip ever,” Mouse declared, and no one disagreed.

As darkness fell, stars began to appear overhead – more stars than Catherine had seen in months, away from the city lights. Vincent tilted his head back to look at them, and Catherine felt his chest rise and fall with a deep, contented breath.

“Thank you,” he murmured.

“For what?”

“For loving me. For sharing this with me. For understanding what it means to me.”

Catherine turned in his arms so she could see his face. In the firelight, his eyes were soft and full of wonder. “Vincent, you don’t have to thank me. This is what love is. Wanting to give you the world – or at least a little piece of sky.”

He kissed her then, slow and deep, and she melted into him, into the warmth of his embrace and the sound of the waves and the crackle of the fire. When they finally pulled apart, she settled back against his chest, and they sat together in comfortable silence, watching the stars wheel overhead.

The white dove cooed softly from its perch on the rocks, and the Hudson River whispered against the shore, and for one perfect night, they were simply two people in love, under an open sky, with all the time in the world.

* * *

The journey back took three days.

They walked back through the crystal cavern, stopping to pick up a few more precious stones. Mouse talked excitedly about what they were made of and how much they might be worth, while Jamie reminded him they still had to carry everything back.

“We’re not pack mules, Mouse,” she said, but her tone was affectionate.

“But look at this one!” He held up a particularly brilliant stone. “This could buy new blankets for half the chambers Below.”

Vincent and Catherine exchanged a smile. Mouse’s enthusiasm was infectious, and his heart was always in the right place.

By the second day, they reached one of the established rest stops – a small chamber that had been outfitted years ago with a cache of supplies. Blankets were stacked neatly in a corner, sealed containers held dried food and water, and someone had even left a small oil lamp with extra fuel.

They settled in gratefully, spreading out the blankets and sharing a simple meal. The exhaustion was starting to set in, but it was the good kind – the kind that came from meaningful adventure and discovery.

“I still can’t believe we found it,” Catherine said, leaning against Vincent’s shoulder. “That hidden cove. It felt like something out of a dream.”

“It was real,” Vincent said softly. “And it will still be there, waiting for us.”

Mouse nodded enthusiastically. “We could go back. Bring supplies. Make it a place people can visit when they need… you know. Sky.”

Jamie squeezed his hand. “That’s a beautiful idea.”

“And the jewels,” Catherine added. “Mouse, I was thinking—what if you and I took some of them to that jeweler who’s a Helper? The one Father mentioned once. We could have them cut and polished. Sell a few?”

Mouse’s eyes lit up. “Yes! Good idea! Very good idea. We could get tools, food, medicine –”

“Blankets,” Jamie interjected with a grin.

“Lots of blankets,” Mouse agreed, grinning back at her.

Vincent was quiet, his hand resting on Catherine’s knee. She glanced up at him and saw something thoughtful in his expression, but he only smiled and pressed a kiss to her temple.

By the third day, they were all feeling the miles. Their legs ached, their shoulders were sore from carrying packs, and the darkness of the tunnels felt heavier after the open sky of the cove. But when the familiar glow of the hub’s lanterns came into view, Catherine felt a surge of warmth.

Home.

They emerged into the hub to find it quiet—most of the community had already retired for the evening. A few people greeted them with smiles and waves, asking how the exploration had gone, but Vincent deflected with his usual quiet grace, promising stories later.

At the entrance to the residential tunnels, the four of them paused.

“Well,” Mouse said, shifting his pack. “That was the best trip ever.”

“Agreed,” Jamie said, leaning into him. “Even if my feet are going to hurt for a week.”

Catherine laughed. “Mine too. But it was worth it.”

Vincent nodded. “Thank you both. For sharing this with us.”

Mouse beamed. “Anytime. We’re a good team.”

They exchanged warm goodnights – Mouse and Jamie heading toward their chamber, Vincent and Catherine toward theirs. As they walked, Catherine felt the exhaustion settling deeper into her bones, but beneath it was a contentment, a sense of fulfillment that made every ache worthwhile.

Their chamber was exactly as they’d left it – quiet, warm, and welcoming. Vincent set down their packs while Catherine lit a few candles, and then they both turned toward the small adjoining alcove where their private bathing pool waited.

The pool was one of the luxuries of their chamber – a natural depression in the stone floor fed by a natural thermal spring. It was always warm, always clean, and always private. Catherine had fallen in love with it the first time she’d seen it.

Now, as she began to undress, she sighed with relief. “I don’t think I’ve ever been this dirty in my life.”

Vincent smiled, pulling off his vest. “The tunnels have a way of clinging to you.”

They slipped into the water together, and Catherine groaned as the heat soaked into her tired muscles. Vincent moved behind her, his hands gentle as he began to wash the dust and grime from her hair.

“That feels amazing,” she murmured, closing her eyes.

They were quiet for a moment, the only sound the soft ripple of water. Then Catherine spoke again, her tone thoughtful.

“Mouse and I will visit the jeweler in a couple of days. I saw how excited Jamie was about the red ruby that was found. It’ll be perfect for the ring. I’m sure Thomas will happily take one of the smaller stones as payment for the setting.” Catherine began washing Vincent’s chest and arms.

“I wonder when Mouse will propose? Did he say anything to you?” Vincent moved his hands to Catherine’s sides.

“No, but I’m sure he will soon after he gets the ring. He’s nervous but eager, ready to pop the question. Oh, Vincent, I’m so happy for them.” Catherine put her arms around Vincent’s waist, drawing closer to feel his warmth.

“The whole tunnel community is expectant. Even Father asked him when he intended to propose.” Vincent explained with a soft chuckle.

“Well, at least Father approves this time. He wasn’t as enthusiastic when you proposed to me.” Catherine rested her face on Vincent’s chest, listening to the soft beat of his heart.

“True, but he loves you, Catherine, and has finally seen the error of his ways. He always asks about you when you’re working. You’ve become an integral part of our community below.” Vincent held Catherine close, kissing the crown of her head.

“Well, let’s just hope Mouse knows what to say.” Catherine chuckled softly. “You might have to help him out so he makes it a bit romantic at least. Jamie loves Mouse’s directness, but a little romance won’t hurt.” She started to massage easy circles around Vincent’s furred chest.

“I will talk with him again,” Vincent murmured against her hair. “I’m sure we’ll come up with something great. Don’t worry yourself about this, my love.”

Catherine tilted her face up to his, and in that moment, words became unnecessary. His lips found hers – soft, tender, a promise made without sound. Her hands stilled against his chest as she surrendered to the warmth of him, the safety of his embrace. What began as comfort deepened into something more, their touches growing languid and deliberate, each caress a whispered affection. Time dissolved into sensation—the gentle lap of water around them, the heat of his skin beneath her fingertips, the quiet intimacy of two souls intertwined. And there, in the sanctuary of their private pool, they lost themselves in each other.

* * *

Two days later, Catherine and Mouse stepped into Thomas Fine Jewelry, a narrow shop tucked between a tailor and a used bookstore in the East Village. The interior was warm and cluttered – display cases lined with velvet trays, a workbench covered in tools, the soft glow of task lighting making everything shimmer.

“Catherine!” Thomas emerged from the back room, wiping his hands on a jeweler’s cloth. The man in his sixties had kind eyes behind wire-rimmed glasses. “And you must be Mouse. Vincent speaks very highly of you.”

Mouse shifted the small leather pouch in his hands, suddenly shy. “Good things?”

“The best things.” Thomas smiled warmly. “Now, what have you brought me?”

Mouse carefully opened the pouch, and several stones tumbled onto the velvet pad—rubies, small emeralds, and clear crystals that caught the light.

Thomas’s eyebrows rose. He picked up the largest ruby, holding it to the light with a jeweler’s loupe. “Extraordinary. This is flawless—Burmese quality.” He glanced up at them.

Mouse nodded eagerly. “For Jamie. Need it perfect.”

“Then it will be perfect, I promise you that.” Thomas set the ruby down gently. “I’ll cut this into a brilliant oval. As for the setting…” He moved to a display case and pulled out a delicate gold band with an elegant, vintage-inspired setting. “I made this for a commission that fell through. Fourteen karat, hand-forged. I’d trade it for one of your smaller emeralds.”

Mouse looked at Catherine, who nodded encouragingly.

“Deal,” Mouse said firmly. “Fair trade.”

“Excellent.” Thomas smiled. “And the rest of these stones?”

Catherine gestured to the remaining pieces. “We’d like to sell a few – the community Below needs funds for winter supplies.”

Thomas examined them thoughtfully. “I can offer you a fair price for three of the smaller rubies and two of the emeralds and crystals.

“That’s more than fair,” Catherine said warmly. “Thank you, Thomas.”

“It’s my honor.” Thomas began writing up a receipt. “The ring will be ready in a week. And Mouse?” He looked up, his expression sincere. “She’s a lucky woman.”

Mouse’s face broke into a wide grin. “I’m lucky one. Very lucky.”

By late afternoon, Catherine and Mouse navigated the crowded Manhattan sidewalks, their arms laden with shopping bags from a bulk grocer, textile shop, and hardware store. They’d gathered dried goods, wool blankets, lamp oil, and batteries – everything the community needed for winter.

“Think we got enough oatmeal?” Mouse asked, shifting a heavy bag.

Catherine laughed. “Mouse, we bought twenty pounds. I think we’re covered.”

“William makes good oatmeal. Everyone likes it.”

“Fair point.” Catherine adjusted her own bags. “You’ve been a huge help today.”

Mouse beamed at the praise, then his expression turned thoughtful. “Catherine? You think Jamie will like the ring?”

“She’s going to love it. But more than that, she loves you. The ring is just a symbol.”

“Good symbol though. Important symbol.” He was quiet for a moment. “Vincent helped me. Told me what to say. Practiced and everything.”

Catherine felt a surge of affection for both of them. “When are you going to ask her?”

“Soon. After ring is ready. Vincent says I should take her somewhere special. Thinking maybe Chamber of the Falls. Pretty there. Romantic.”

“That’s perfect,” Catherine said softly. “She’ll remember it forever.”

They hailed a cab at the next corner. The driver’s eyes widened at the sheer volume of bags they loaded into the trunk and the back seat.

“Moving in somewhere?” he asked.

“Something like that,” Catherine said with a smile.

The drive to the brownstone took 20 minutes through rush-hour traffic. By the time they pulled up to the familiar brick facade, the sun was beginning to set, painting the street in shades of amber and gold.

Catherine paid the driver, and they began unloading bags. She was reaching for the last one when she felt it – that familiar warmth in her chest, the gentle pull of awareness that meant Vincent was near.

Vincent stood inside the doorway, hidden from view, his expression soft with welcome. He’d clearly sensed her approach, that invisible thread between them drawing him to her as surely as gravity. He moved down the steps with fluid grace, his eyes finding hers immediately.

They stepped inside, hauling in all the bags.

“You’re back,” he said, and there was such warmth in his voice that Catherine felt it settle around her like an embrace.

“We are,” she said, smiling. “And we brought half the city with us.”

Vincent’s gaze shifted to the pile of bags, then to Mouse, who was trying valiantly to carry three bags at once. “I can see that. Here – let me help.”

He took the heaviest bags as though they weighed nothing, and Mouse looked relieved. “Thanks, Vincent. Good timing.”

“I felt Catherine coming home,” Vincent said simply, as though it were the most natural thing in the world. His eyes met hers again, and something warm passed between them – that constant, quiet awareness of each other that never faded.

They carried everything inside and down to the basement, where a familiar section of wall stood slightly ajar – the hidden entrance to the tunnels Below. Vincent pushed it open fully, revealing the warm glow of torchlight beyond.

One Week Later

The Chamber of the Falls glowed with moonlight filtering through the high opening. Mouse had arranged smooth stones in a circle near the pool’s edge with a single candle protected by glass –Vincent’s handiwork. His heart hammered as he heard Jamie’s footsteps echoing off the stone walls.

She emerged from the tunnel passage, eyes widening at the scene. “Mouse? What is all this?”

“Come,” he said, taking her hand. “Special place. Remember?”

“Of course.” Jamie looked around, wonder in her eyes.

Mouse took a breath, his palms sweating. He thought of Vincent’s coaching, but suddenly the practiced words didn’t matter. Only Jamie mattered—her hand in his, the candlelight in her hair, the way she looked at him.

“You make me brave,” he said simply. “You make everything better.”

He dropped to one knee, and Jamie’s hand flew to her mouth.

Mouse pulled the velvet box from his pocket. Inside, the ruby blazed like a tiny flame against the delicate gold band.

“Jamie, will you marry me?”

“Yes! Yes, of course, yes!” She pulled him up, laughing and crying at once.

Mouse slipped the ring onto her finger. Jamie held her hand up to the light, watching the ruby sparkle. “It’s beautiful.”

“Jamie is more beautiful,” Mouse said, and then he was kissing her, and the waterfall sang around them like a blessing.

Mouse and Jamie broke apart, breathless and glowing. Jamie threw her arms around Mouse, and he lifted her off her feet, spinning her around while she laughed with pure delight.

“We’re getting married!” she cried out to the cavern.

The following day, Mouse bumped into Catherine and Vincent on their way to the dining chamber.

“She said yes!” he announced. “Jamie said yes!”

“Of course she did,” Catherine said warmly, embracing Mouse. “Congratulations.”

The bedroom was warm and intimate, lit only by the soft glow of the bedside lamp. Catherine lay against the pillows in her silk nightgown, her hair loose around her shoulders. Vincent was beside her, propped on one elbow, watching her with that particular intensity that still made her heart quicken after all this time.

“I have something for you,” he said quietly.

Catherine smiled, curious. “What is it?”

Vincent reached for the nightstand and retrieved a small velvet box. Catherine’s breath caught. She sat up slightly, her eyes widening as he opened it to reveal a pendant – the emerald from the crystal cavern, cut into a perfect teardrop and set in delicate silver on a fine chain.

“Vincent…” she whispered. “This is… when did you…?”

“Pulled it out while you were distracted by the light,” he confessed, his voice soft.  “I’ve been keeping it secret, waiting for the right moment.” He paused, his eyes searching hers. “Thomas cut and set it for me. I wanted it to be perfect for you.”

Catherine reached out, her fingers trembling slightly as she touched the emerald. It caught the lamplight and glowed like captured starlight – green, luminous, and impossibly beautiful.

“It’s exquisite,” she breathed. “Help me put it on?”

Vincent lifted the chain from the box and fastened it gently around her neck. The emerald settled against her collarbone, and he traced its curve with his fingertips, his touch reverent.

“It suits you,” he murmured. “Like it was always meant to be yours.”

Catherine caught his hand and brought it to her lips, kissing his palm. “I love it. I love you.”

“I love you,” he said, and there was warmth in his voice – that quiet certainty that had always been theirs.

They lay back together, Catherine nestled against Vincent’s chest, her fingers playing with the emerald pendant. After a moment, she spoke.

“We should go back,” she said softly. “To the alcove. Before winter comes.”

Vincent’s arms tightened around her. “I was thinking the same thing.”

“We could camp there,” Catherine continued, her excitement building. “Three days, as we talked about. Just us.”

“We could store supplies there,” Vincent added, already planning. “In that open chamber near the pond. Camping gear, blankets, provisions. That way, we could make the journey more comfortable and return whenever we wish.”

Catherine lifted her head to look at him, her eyes bright. “Multiple trips through the seasons.”

“Yes,” Vincent said simply. “A place we can truly enjoy.”

Catherine settled back against him, her hand still touching the emerald at her throat. “In a few weeks, then. Before the cold sets in.”

“In a few weeks,” Vincent agreed.

They lay in comfortable silence, listening to the city sounds beyond their windows—the distant hum of traffic, the occasional siren, the life of New York continuing on above them. But here, in this room, in this bed, they existed in their own world. Catherine’s fingers traced lazy patterns on Vincent’s chest, feeling his heartbeat steady and strong beneath her palm. Vincent’s hand moved through her hair, his touch gentle and reverent.

“Thank you,” Catherine whispered, “For always thinking of me.”

Vincent turned his head and kissed her forehead, then her temple, then found her lips. The kiss was slow and deep, full of tenderness. When he pulled back, his eyes held hers.

“You are my future,” he said. “Everything else is just the beautiful details.”

Catherine smiled against his lips and kissed him again, happy in the knowledge that Vincent could now enjoy a wider expanse of the sky.
