Chapter 17: The Boundary Between Water and Light（2）

The afternoon sun was bright, but the lakeshore was veiled in thin mist. Blackwood Manor’s lake was a natural body of water, not large but said to be deep. The water was dark green, its surface mirror-smooth, reflecting the surrounding trees and sky.

They followed a path toward the lake. Lucy suddenly stopped.

“Do you hear that?” she asked softly.

Isabella listened. Beyond the wind and birdsong, there was a faint sound—like water gurgling, coming from somewhere near the lake.

They followed the sound to the lake’s northern shore, where they discovered a hidden entrance: a half-submerged stone archway that appeared to be the remnant of some ancient structure. Water was flowing gently from it, forming a small stream.

“What is this?” Lucy approached curiously.

“I don’t know. I was always warned not to come near the lake.” Isabella glanced around and noticed something glinting in the grass near the shore. She walked over and picked up a small silver brooch shaped like a lavender flower.

Identical to the pendant on the necklace her mother had left her.

“This belonged to my mother,” she whispered, her fingers tracing the cool silver. “She must have been here.”

Lucy had already approached the stone archway, crouching to examine it. “There are steps here, leading underwater. The water’s clear—I can see something below.”

Isabella joined her. Indeed, stone steps descended, disappearing into the green water. About a meter down, she could vaguely make out a metallic object—something like a box.

“I’ll go down and look,” Lucy said, starting to remove her shoes.

“Wait, it’s too dangerous!” Isabella grabbed her arm.

“The water’s shallow, I can hold my breath,” Lucy smiled. “In Devon, I often retrieved lost things from streams.”

Before Isabella could stop her, Lucy stepped into the water. It reached only to her waist but was icy cold. Lucy took a deep breath and submerged.

Time seemed to freeze. Isabella stared at the water, watching Lucy’s golden hair float like seaweed beneath the surface, her heart racing. Ten seconds, twenty, thirty...

Just as she prepared to jump in, Lucy surfaced, clutching a small, rusted iron box. She gasped for air, her face lit with an excited smile.

“Found it! It’s locked, but not too heavy.”

They returned to shore, Lucy shivering in the sunlight, dripping wet. Isabella removed her own shawl to wrap around her, then examined the iron box.

The box was small, about thirty centimeters long and twenty wide, its surface heavily corroded but the lock still secure. On the lid was carved a faded crest—not the Blackwood family’s black eagle, but an unfamiliar symbol: intertwined roses and a sword.

“We’ll need tools to open it,” Isabella said. “Let’s return first—you need dry clothes.”

***

Back at the manor, Lucy indeed required a change of clothes. She was soaked through, mud and lake water mingling on her, looking disheveled yet vibrantly alive. Isabella prepared hot water for her, her own mind unsettled—the box, the brooch, the clues all pointed to a hidden truth.

Steam from the bathwater rose in the room, creating a hazy mist. Lucy removed her wet clothes and stepped into the tub, sighing with relief. Isabella turned her back, pretending to arrange towels, but her fingers trembled slightly.

“Could you help wash my back?” Lucy’s voice came through the steam, soft and natural. “I can’t reach... there’s still mud in some places.”

Isabella’s body stiffened. This was a second boundary, more intimate than unfastening buttons, more dangerous than a glimpse of bare skin. In Victorian times, such intimate contact existed only between mother and young daughter, or maid and mistress, always accompanied by strict distance and propriety.

But she couldn’t refuse.

She turned and approached the tub. The steam blurred her vision, but the outline of Lucy’s back was clear—slender shoulders, the dip of her spine, water droplets sliding down her skin and disappearing into the bath. Isabella picked up a sponge, dipped it in warm water, then gently placed it on Lucy’s back.

The first touch made both of them tremble slightly. The sponge was warm and soft, making a faint sound against skin. Isabella began to move her arm, clumsy but gentle, washing away the mud stains from Lucy’s back. Her eyes couldn’t leave that skin—so real, so vulnerable, so beautiful.

“Your hands are shaking,” Lucy said softly, not turning.

“I’m sorry.”

“Don’t apologize.” Lucy shifted slightly, water rippling. “I like it when you touch me.”

Isabella felt her cheeks flush. Through the sponge, her fingers could feel the warmth of Lucy’s skin, the rise and fall of her back as she breathed. This simple act suddenly became immensely intimate, immensely significant, filled with emotions she couldn’t articulate.

When she finished washing Lucy’s back, Lucy suddenly turned around. Water rippled, the body beneath the surface appearing and disappearing. Their eyes met through the steam, grey-blue meeting grey-blue, some unspoken communication passing between them.

“You’re wet too,” Lucy said, looking at Isabella’s dampened sleeves. “You should...”

She didn’t finish. Because Isabella did something that surprised even herself—she leaned down, gently brushed aside the wet golden hair from Lucy’s cheek, and pressed a kiss to her smooth forehead.

Light as a feather, brief as a heartbeat.

But enough.

Lucy’s eyes widened, then softened, filling with a warm light. Her hand rose from the water, wet fingers lightly touching Isabella’s cheek.

“Again,” she whispered.

Isabella closed her eyes and leaned down once more. This time, her lips met Lucy’s—warm, damp, carrying the fresh scent of mint toothpaste and hot water. This kiss was more real than last night’s, deeper, more unrestrained. Her fingers tangled in Lucy’s wet hair, Lucy’s arms encircled her neck, pulling her closer.

Water rippled, steam rose, the world shrank to this bathroom, this tub, this kiss.

When they finally parted, both were breathless. Isabella’s sleeves were thoroughly soaked, but she didn’t care. She knelt by the tub, forehead resting against Lucy’s, eyes closed, feeling the truth of this moment.

“I love you,” Lucy whispered, her voice weighted with steam and emotion.

“I love you too,” Isabella responded, saying the words without reservation for the first time. “In all permitted and forbidden ways. In all named and unnamed ways.”

They remained like that for a long time, in the steam and water, in kisses and touches, in truth and vulnerability. Until the water began to cool, until reality knocked once more.

Footsteps sounded outside the bathroom, followed by Mrs. Hudson’s voice: “Miss Blackwood? The iron box has been opened. You should come see what’s inside.”

They separated, their eyes exchanging a decision: whatever the box contained, whatever the truth, they would face it together.

Because at the boundary between water and light, between kisses and truth, they had found something more important than any secret:

Each other.

***

The iron box lay open on the study desk. Its contents were few but bewildering:

A yellowed marriage certificate dated September 1780, bearing the names “Eleanor Blackwood” and “Edward Coventry.”

A letter addressed to “My dearest Edward,” signed “Your Eleanor,” dated February 1781, mentioning her pregnancy but stating “the family will never accept our union.”

A birth certificate recording a male infant’s birth: March 15, 1781, mother Eleanor Blackwood, father Edward Coventry. The space for the infant’s name was blank.

And a small portrait of a young woman with honey-colored hair and grey-blue eyes—strikingly similar to Isabella. On the back was written: “To my daughter, wherever she may be. Love, your mother, Eleanor.”

Isabella picked up the portrait, her fingers trembling. The woman in the painting smiled, her eyes gentle yet sad. This was the first time she had “seen” her mother’s face.

“Eleanor Blackwood,” Mrs. Hudson’s voice came from the doorway as she entered, her expression complex. “The old marquess’s only daughter, your mother. She fell in love with an unsuitable man—a surveyor, a commoner.”

“And Prince Edward...” Lucy guessed.

“Not him,” Mrs. Hudson shook her head. “Edward Coventry died many years ago. But I suspect the Prince may be a relative—a nephew or cousin. That would explain his interest in your origins.”

Isabella stared at the documents. “So I am truly of Blackwood blood? Eleanor’s daughter?”

“Yes,” the older woman nodded. “But you were born illegitimate. To the old marquess, that was worse than not being of his blood at all. So he arranged an exchange: a healthy female infant from a tenant farmer’s family would replace you, while you would be sent to a French convent to be raised. But your mother... she couldn’t bear it. At the last moment, she changed the plan and entrusted you to a childless distant relative—the Millers.”

Lucy inhaled sharply. “Then I...”

“You are the tenant farmer’s daughter,” Mrs. Hudson said gently. “But you grew up at Blackwood Manor, learning how to be an heiress. And Isabella grew up in Devon, learning how to live authentically.”

The truth was so simple, so complex, so ironic. Isabella felt dizzy, steadying herself against the desk.

“And the lake?” she asked. “Why were my mother’s things there?”

Mrs. Hudson was silent for a moment. “Eleanor and Edward often met there secretly. Behind that stone archway is a small cave where they would rendezvous. I believe she hid these things there, hoping one day you would find them.”

Lucy took Isabella’s hand. “So we are... exchanged children. But what was exchanged wasn’t our fates, but our ways of living.”

Isabella looked at Lucy, at this girl with whom she had exchanged lives, and suddenly understood something. “Perhaps the exchange wasn’t a mistake, but a gift. Because of it, I learned authenticity. Because of it, you learned responsibility. And now...”

“And now we can choose,” Lucy finished for her. “Choose how to live, choose whom to love, choose who to become.”

Mrs. Hudson looked at their joined hands, a glimmer of tears in her eyes. “Eleanor would be proud of you. She always said true love shouldn’t be bound by status or rules.”

She turned and left, gently closing the door behind her, granting them privacy.

Isabella turned to Lucy, her grey-blue eyes filled with tears but her lips curved in a smile. “So what now? We have three letters to answer, a truth to face, a world to challenge.”

Lucy kissed away the tears at the corners of her eyes. “We’ll take it step by step. First, reply to the Duke of Winston: we refuse his proposal. Then, reply to Prince Edward: thank him for his concern, but our choice is clear. Finally...”

“Finally?” Isabella asked.

Lucy smiled, that sun-bright smile. “Finally, we write our own story. A story about two girls, an exchanged truth, and a love that shouldn’t exist but does.”

Outside the window, the setting sun painted the sky gold and purple. In Blackwood Manor’s study, amid scattered documents and ancient secrets, two girls held hands, ready to face the future together.

Because they finally knew:

The deepest secret wasn’t in the water, nor in the documents, nor in titles or bloodlines.

It was in their joined hands, in their exchanged gazes, in the forbidden yet bravely blossoming love.

That was their true inheritance.

That was the truth they had chosen.
