Chapter Three - The Letter

Sophie didn't sleep.

She lay in her own bed down the hall, the unmarked key pressed into her palm like something she couldn't bring herself to set down, turning over every possibility until the ceiling above her blurred from exhaustion. She'd found a storage unit, rented under a false name — she'd found the paperwork tucked into the same drawer, a receipt for a unit across the city, paid for in cash every month for the better part of a year. Charlotte had been keeping a life Sophie knew nothing about. The thought sat wrong in her chest, heavier than the wedding, heavier than the lie she was currently living in her sister's place.

She said to herself " what if this key means nothing" 

They had told each other everything once. That was supposed to be the whole point of being a twin — two people who never had to explain themselves, who finished each other's sentences before either of them needed to. Somewhere in the last few years that had quietly stopped being true, and Sophie hadn't noticed until the gap had grown wide.

By the time grey light started creeping through the curtains, she'd made a decision. She would go to the storage unit herself, today, before the next round of wedding obligations swallowed the day whole. Whatever Charlotte had been hiding, Sophie needed to see it before anyone else did.

She didn't get the chance before nine a.m.

"You have a fitting," her mother announced, appearing in the doorway already dressed, already composed, as if the previous night's crack in her armor had never happened. "And then lunch with Julian's brother. He requested it specifically."

Sophie sat up too fast. "Theo wants to have lunch with me?"

"He called this morning. Said it was a courtesy, getting to know the bride properly before the wedding." Margaret's mouth pressed into a thin line. "I don't like it either. But saying no would look strange, and we cannot afford strange right now."

Sophie had met Theo Calloway exactly twice — once at the engagement party, where he'd spent most of the evening on his phone, and once at a fundraiser where he'd barely spoken three sentences to her. He was younger than Julian by two years, sharper in some ways, looser in others, the kind of person who noticed everything and said nothing about most of it. She had no idea what he wanted.

The fitting came first, two hours trapped in a glass-walled studio while a seamstress pinned and unpinned the same three inches of fabric along the bodice, murmuring about Charlotte's measurements from the last appointment and how strange it was that they'd shifted slightly in just a few weeks. 

The wedding was eleven days away. She tried not to think about what that meant if Charlotte still hadn't surfaced by then, and failed. She could only hope.

She found out at half past noon, seated across from him at a quiet restaurant near the river, white tablecloth between them, Theo's expression unreadable in a way that reminded her uncomfortably of his brother. He'd chosen the table himself, she noticed — tucked into a corner, away from the windows, away from anyone who might recognize the Calloway name and come over to offer congratulations neither of them wanted to receive right now.

"You don't remember me," he said, before she'd even fully settled into her chair.

"Of course I remember you," Sophie said carefully. "We met at the engagement party."

"That's not what I mean." He folded his hands on the table, watching her with the kind of patient attention people used when they already knew the answer to their own question. "I mean you don't remember the dinner four years ago. The one at my father's house, when Charlotte brought her sister along because she didn't want to come alone, and the two of you switched seats halfway through so Charlotte could escape a conversation with our great-aunt about fertility treatments."

Sophie's stomach dropped through the floor.

She remembered that dinner. She remembered it perfectly — remembered laughing with Charlotte in the bathroom afterward about how easy it had been, how no one at the table had noticed a thing. 

"I don't know what you're talking about," she said.

"I do." Theo's voice was quiet, almost gentle, He shrugged. "I was paying attention. I've been paying attention again, this week."

Sophie reached for her water glass to give her hands something to do. "And what exactly have you concluded, paying attention?"

"That you're not Charlotte." He said it simply, without theater, the way someone announced a fact about the weather. "I don't know why. I don't know where she actually is. But I know my brother well enough to know he's already half-convinced of it too, and the only reason neither of us has said anything yet is that we're both trying to figure out why you'd do this before we decide what it means."

The restaurant noise continued around them, oblivious — silverware against china, the low murmur of other conversations, a waiter passing with a tray of wine. Sophie felt suddenly and completely alone inside it, exposed in a way that had nothing to do with anyone else in the room noticing.

"If you tell your father," she said slowly, testing each word before she let it out, "the wedding is over. My mother loses everything she's spent a decade building. And you still won't know where Charlotte actually is."

"I'm aware."

"Then why haven't you said anything?"

Theo studied her for a long moment, something shifting behind his eyes that she couldn't quite name. "Because Julian asked me not to. Not yet."

That stopped her cold. "He asked you to keep quiet?"

"He wants to handle it himself." Theo leaned back, finally breaking eye contact to glance out the window at the grey river beyond. "Which, frankly, worries me more than you do. My brother doesn't protect people without a reason, and he's never once in his life made an exception to a rule without deciding it benefited him somehow." He looked back at her. "So I'd like to know which one you are. The danger he's protecting, or the exception he's making."

Sophie didn't have an answer for that. She wasn't sure there was a clean one.

"I need to find my sister," she said instead, because it was the only true thing she had left to offer him. "That's all this is. I'm not trying to steal anything, I'm not trying to hurt anyone, I'm trying to buy enough time to find out what happened to her"

Something in Theo's expression softened, just slightly, just enough that she could see a flicker of the boy who'd once found a teenage prank more interesting than fertility treatments. "Then let me help you," he said. "I have resources you don't. Private investigators my father uses for things he doesn't want surfacing in the press. I can have someone looking by tonight."

It was, unexpectedly, the first real offer of help Sophie had received since this began — no conditions, no warnings about what happened if it fell apart, just a hand extended across a white tablecloth from someone who had every reason to expose her and hadn't.

She almost said yes.

She was still searching for the right words when their waiter returned, setting down a fresh glass of water at her elbow with practiced efficiency. He lingered half a second longer than necessary, just long enough to slide something small and folded beneath the edge of her napkin before straightening and moving on to the next table, as if he'd done nothing at all.

Sophie's heart stopped.

"Everything all right?" Theo asked, watching her face.

"Fine," she managed, sliding her hand beneath the napkin to close her fingers around the folded paper. "I think I just need some air. Would you excuse me a moment?"

She didn't wait for his answer. She made her way toward the back of the restaurant, past the kitchen doors, until she found a quiet alcove near the restrooms where no one could see her hands shake as she unfolded the note.

The handwriting stopped her cold. She would have known it anywhere — the same looping C, the same hurried slant Charlotte had carried since they were children passing notes under their desks at school.

Sophie. I know you're wearing my face right now. I'm sorry. I had no choice — I can't marry a man I don't know. I'll find a way to reach you properly. Burn this.

Sophie read it twice, three times, her mind racing through everything it implied — that Charlotte was alive, that she'd known almost immediately Sophie had taken her place, and that whatever had driven her away wasn't danger at all. It was simpler than that, and somehow harder to forgive. Charlotte had run from a wedding she never wanted, and left Sophie standing in the wreckage of it, pretending to want what her sister couldn't bring herself to even pretend at.

She looked up to find the waiter standing a discreet distance away, watching her with an expression that had nothing to do with hospitality.

"Who gave you this?" she whispered.

"A woman," he said quietly. "She didn't give a name. Said to tell you—" He hesitated, glancing once toward the dining room before continuing. "Said to tell you she's sorry, and that she's running out of time to figure out what to do."

He turned and disappeared back toward the kitchen before Sophie could ask anything else, leaving her alone in the alcove with her sister's handwriting trembling in her hands and a single, aching realization settling into her chest.

Charlotte hadn't vanished because something happened to her.

She'd run because she couldn't face becoming Julian's wife.
