The ICU waiting room at four in the morning was a purgatory of vinyl and fluorescent light. Ava sat in the same chair she'd claimed hours ago—third from the end, facing the double doors, her spine still carrying the dancer's postural memory even as exhaustion hollowed her out from the inside. Her hands rested on her thighs, fingers pressing into the denim of jeans that weren't hers, that Sarah had grabbed from the house without asking. The fabric was stiff. Unfamiliar. Everything was unfamiliar.

Sarah sat two chairs over, her phone a pale rectangle in her grip, the glow casting shadows up her face. She hadn't spoken in an hour. Maybe longer. Time had gone liquid in this room, pooling and stretching until the clock on the wall felt like a suggestion rather than a fact.

Maggie paced. Back and forth, seven steps each way, from the edge of the vinyl chairs to the wall where a faded print of a landscape hung crooked. She'd taken her boots off at some point—Ava didn't remember when—and her bare feet made soft sounds on the linoleum. The collar at her throat caught the light each time she turned.

Elizabeth sat in the corner chair, the one with the armrest that wobbled. She'd been still for so long that Ava had checked twice to make sure she was breathing. Her eyes were red-rimmed, the kind of redness that came from tears she'd refused to let fall, and her hands gripped the armrests until her knuckles went white, then released, then gripped again. A cycle. A pulse. The only movement she allowed herself.

The coffee on the table beside Sarah had gone cold hours ago. A thin skin had formed on its surface, and the smell had soured, mixing with the antiseptic that seemed to live in the very walls of this place. Ava had stopped noticing it until a passing nurse opened the door to the corridor, and a fresh wave of it hit her—sharp, chemical, clinical—before the door swung shut again.

No one had come through those double doors in forty-seven minutes. Ava knew because she'd counted.

"You should sit down," Sarah said, her voice rough from disuse. She didn't look up from her phone.

Maggie stopped pacing. Stood in the middle of the room, barefoot, her shorn hair sticking up at angles she hadn't bothered to smooth. "I can't."

"You've been walking for three hours."

"Then what's three more minutes."

Sarah looked up then. Her eyes were tired, but there was something else there—something harder, something that had been sharpening in the hours since they'd lied to the police officer on the phone. "You think pacing brings him back faster?"

"I think sitting makes me feel like I'm giving up."

"Sitting is waiting. Pacing is just waiting with more steps."

Maggie's jaw tightened. She looked at Sarah for a long moment, something passing between them that Ava couldn't quite read—history, maybe, or the particular language that formed between women who had been broken in the same house. Then Maggie sat. Dropped into the chair beside Ava, the vinyl groaning under her weight. Her shoulder pressed against Ava's. Solid. Warm.

Ava didn't move away.

"He's going to wake up," Maggie said. Not a question. A statement, flat and deliberate, as if saying it aloud made it true.

Ava wanted to believe her. She wanted to let the words settle into her chest and take root there, a certainty she could hold onto. But she had seen him collapse. Had heard the rattle in his chest. Had watched the paramedics work him, the AED's voice flat and mechanical— shock advised, stand clear —and the way his body had arched off the floor when the current hit him.

She had seen him die. Just for a moment. Just long enough for the world to tilt.

"Ava." Sarah's voice, sharper now. "Look at me."

Ava lifted her head. Sarah was watching her with that same hard-edged attention, the one she used when she was assessing, calculating, figuring out how to hold the line.

"He's going to wake up," Sarah said. "He's stubborn. He's mean. He doesn't know how to stop. That kind of man doesn't die in a hospital bed with a tube down his throat."

"That's supposed to comfort me?"

"It's supposed to be true." Sarah set her phone face-down on her thigh. "The comfort part is your job."

Ava let out a breath she hadn't realized she was holding. It came out shaky, uneven, and she pressed her palms flat against her jeans again, feeling the texture of the denim, the solidity of her own body. She was here. She was alive. Caleb was alive, somewhere behind those doors, his chest rising and falling with a machine's rhythm instead of his own.

The double doors opened.

Nathalie came through them like she'd been poured from the same mold as the fluorescent lights—pale, clinical, unyielding. Her scrubs were wrinkled at the elbows, dark circles carved deep beneath her eyes, and her hair had escaped its ponytail in strands that clung to her cheek. She was holding a piece of paper. The edges trembled slightly, the only tell that she was anything other than composed.

Ava was on her feet before she knew she'd moved.

Nathalie stopped in the center of the room, her gaze moving across each of them—Ava, Maggie, Sarah, Elizabeth in her corner. The paper trembled again, and she folded it once, twice, pressing the crease with her thumb.

"The tox screen came back," she said.

The words hung in the air. Ava felt them land in her chest like stones dropped into still water, each one sending ripples outward.

"It's mercury," Nathalie said. "Inorganic mercury. Introduced while he was in observation, likely through his IV line."

Sarah's phone clattered against her thigh as she set it down. "Through his IV?"

"Someone injected it into the line. A significant dose. Enough to cause the seizure-like symptoms, the amnesia, the cardiac arrest." Nathalie's voice was steady, clinical, but there was something underneath it—a roughness, a frayed edge. "This wasn't an accident. This was deliberate."

Deliberate.

The word sat in the room like a physical thing. Ava felt it press against her ribs, cold and heavy. Someone had done this. Someone had walked into a hospital room, into the space where Caleb lay unconscious after his procedure, and injected poison into his veins.

Maggie was on her feet now. "Who."

"We don't know."

"Who had access. Who was in his room." Maggie's voice was low, controlled, the voice of a cop asking questions she already knew the shape of. "Visitors. Staff. Anyone."

Nathalie met her gaze. "The room wasn't under surveillance. Standard post-procedure observation—nurses checked vitals every hour, but there were gaps. Fifteen, twenty minutes at a time overnight when no one was actively in the room."

"Twenty minutes," Maggie repeated. "That's all it takes."

Sarah stood. Her movements were careful, deliberate, the same control she used when she was about to do something that required precision. "Mercury. How much?"

"Enough to kill him." Nathalie's voice cracked on the last word, just slightly, before she caught it. "If we hadn't caught the cardiac arrest when we did, if the paramedics hadn't been fast enough—"

"But they were." Sarah stepped closer, her eyes locked on Nathalie's. "He's alive. He's in a coma, but he's alive. So what happens now?"

"Chelation therapy. We've already started. It binds to the mercury and helps the body excrete it. But the damage—" Nathalie stopped. Swallowed. "The neurological damage depends on how long it was in his system before we started treatment. We don't know when it was administered. We don't know how long it circulated."

"He didn't remember us," Ava said. Her voice came out smaller than she wanted, and she felt Maggie's hand find her forearm, steadying. "When he woke up after the procedure. He didn't know Sarah. He didn't know Elizabeth. He didn't know Maggie. He only knew me."

Nathalie nodded slowly. "Retrograde amnesia is consistent with mercury toxicity. The memories may come back. They may not. It depends on the extent of the damage."

"And the coma?" Sarah asked.

"Induced. Cooling protocol to reduce metabolic demand and limit further injury. We'll start warming him tomorrow if his vitals hold."

Tomorrow. The word felt impossibly far away. Ava looked at the double doors, at the strip of light visible where they didn't quite meet, and felt the weight of everything that lay beyond them. Caleb, wired to machines. Caleb, his chest rising and falling in someone else's rhythm. Caleb, who had held her face in his hands and told her she was his, who had marked her with rings and a collar and a name, who had looked at her without recognition and asked for his father.

In the corner, Elizabeth moved.

It was a small thing—a shift of weight, a flexing of fingers. Ava looked at her, and saw that Elizabeth's knuckles were still white, still gripping the armrest like it was the only thing keeping her upright. Her face was pale, the red around her eyes deeper now, and there was something in her expression that Ava couldn't name. Something raw. Something that looked like it was being held together by sheer force of will.

"Elizabeth?" Sarah's voice was careful, questioning.

Elizabeth stood. The chair scraped against the linoleum, a harsh sound that cut through the humming silence. "I need air."

Her voice was flat. Controlled. But Ava saw the way her hands trembled as she pushed a strand of hair behind her ear, saw the way her jaw was clenched so tight that the muscles in her neck stood out.

"Elizabeth," Sarah said again, taking a step toward her. "Talk to me."

"I can't." Elizabeth's gaze flickered to Sarah, then away. "I can't do this right now. I need—I just need a minute."

She was already moving toward the exit door—the one that led to the stairwell, not the main corridor. Her hand found the push bar. The door groaned open, and a wash of colder air bled into the waiting room, carrying the echo of concrete and dust.

"Liz." Sarah's voice was sharper now, edged with something that might have been fear. "Don't—"

The door clicked shut behind Elizabeth.

The sound was soft. Final. It settled into the room like a held breath released, and for a long moment, none of them moved.

Ava stared at the door. The metal surface was scuffed, painted over too many times to count, with a small window of wire-reinforced glass showing nothing but the gray concrete of the stairwell beyond. She could see the first few steps, leading down, and the stark white of the wall across from them.

No movement. No sound. Just the fluorescent hum, steady and indifferent.

Sarah let out a breath. "Okay." She ran a hand through her hair, the gesture rough, uncalculated. "Okay. She needs a minute. We give her a minute."

"She's been barely holding it together for hours," Maggie said. Her voice was quiet, not accusatory, but weighted with observation. "Since before we got here. She hasn't slept. She hasn't eaten. She's just been sitting in that chair, staring at the wall."

"I know." Sarah's phone buzzed in her hand, and she glanced at it, then set it face-down on the table beside the cold coffee. "I know."

Nathalie was still holding the folded paper. She looked at it, then at the door Elizabeth had disappeared through, then back at the three women standing in the harsh light. "I should check on her."

"No." Sarah's voice was firm. "She said she needs a minute. We give her a minute."

"She's my patient's girlfriend. She's a potential witness in a criminal investigation. I have a duty—"

"She's a woman who just found out someone tried to kill the man she loves," Sarah cut in. "And she's been sitting in a corner for six hours without crying, without breaking, without letting anyone see her fall apart. If she needs a stairwell and a few minutes of silence, we give her that."

Nathalie held her gaze for a long moment. Then she nodded, once, and folded the paper again, sliding it into the pocket of her scrubs.

Ava sat back down. The vinyl creaked under her, and she felt the cold of it through her jeans, the way it clung to her skin. She looked at the door again. Still closed. Still silent.

She thought about Elizabeth's earring—a small silver stud, the kind of thing you put in without thinking, without choosing, because it was always there. She thought about the way Elizabeth had touched it earlier, a nervous habit, twisting it between her fingers while she stared at nothing.

She thought about the stairwell, and the concrete, and the cold.

Maggie sat down beside her again. Her shoulder found Ava's, the same spot as before, and Ava leaned into it, just slightly. Just enough to feel the warmth of another body.

"Twenty minutes," Maggie said quietly. "That's what Nathalie said. Twenty-minute gaps in observation. Someone walked into his room, injected mercury into his IV, and walked out again, and no one saw a thing."

"We don't know that," Sarah said. "We don't know anything yet."

"I know there's an empty propofol vial in a drawer at the house." Maggie's voice was flat. "I know his amnesia wasn't natural. I know someone wanted him dead."

Ava closed her eyes. The fluorescent light pressed against her lids, orange and red, the afterimage of the room burned into her vision. She could hear the hum of the lights, the distant beep of a machine somewhere in the ICU, the soft rustle of Sarah's jacket as she shifted her weight.

And behind all of it, the silence of the stairwell.

Elizabeth had been gone for two minutes. Maybe three. It felt longer.

Ava opened her eyes. The door was still closed. The window showed nothing but concrete and the first few steps, leading down into a darkness the fluorescent light couldn't quite reach.

She counted the seconds. She couldn't help it—her mind had latched onto numbers as something solid, something that made sense in a world that had lost all shape. One. Two. Three. The rhythm of her own heartbeat. Four. Five. Six. The space between one breath and the next.

At the count of sixty, she stopped. One minute. Elizabeth had been gone one minute.

There were nineteen more to go.

Sarah's phone buzzed again. She picked it up, glanced at the screen, and set it back down without answering. Her jaw was tight, her shoulders set in a line that dared anyone to ask.

Nathalie had moved to the window at the far end of the room, looking out at the parking lot below, the streetlights casting pools of orange on the asphalt. Her back was straight, her hands in her pockets, and the curve of her spine held the same tension as the rest of them—coiled, waiting, ready to break.

"We need to call the police," Nathalie said, without turning around. "Not the officer who came to the house. The hospital security. This is a crime scene now."

"They already know," Sarah said. "The tox screen triggered an automatic report. Hospital admin is involved. There's going to be an investigation."

"Then we need to tell them what we know." Nathalie turned, her face unreadable in the half-light. "The propofol. The amnesia. The timeline. Everything."

Maggie's hand tightened on Ava's forearm. "And what do we tell them about us?"

"The truth."

"Which version?" Maggie's voice was sharp now, a blade that had been waiting to be drawn. "The version where we're his friends? His housemates? The version where we don't know his last name, even though three of us wear his collar?"

The word landed. Nathalie's gaze flickered to Maggie's throat, to the leather band that circled it, stark against her skin.

"We figure it out," Sarah said. "One step at a time. First, Caleb lives. Then we deal with the rest."

Ava looked at the door again. Still closed. Still silent.

Elizabeth had been gone five minutes. Maybe more. Time had gone liquid again, pooling and stretching, and Ava couldn't trust her own count.

She thought about the earring. The small silver stud, the way it caught the light when Elizabeth moved. She thought about the stairwell, and the concrete, and the cold.

She thought about the fact that no one had followed her yet.

"I'm going to check on her," Ava said, and stood before anyone could argue.

The door was heavier than she expected. Ava pushed through into the stairwell, and the sound of it closing behind her was a dull thud that swallowed itself in the concrete silence.

Cold air hit her face first. Then the smell—dust and bleach and something metallic, the particular scent of a space that saw foot traffic but never lingered in. The fluorescent hum was different here, lower, a frequency that sat in her teeth rather than her ears.

"Elizabeth?"

Her voice echoed. Bounced off the concrete walls, up the stairwell, down into the darkness below. The sound of it felt wrong—too loud, too human in a space designed for passing through, not staying in.

No answer.

Ava took the first step down. The concrete was cold through her sneakers, the soles of her borrowed shoes making a soft scuff against the grit on the surface. She peered around the first landing, expecting to see Elizabeth sitting against the wall, arms wrapped around herself, face hidden in her knees.

Nothing.

The landing was empty. A cigarette butt in the corner. A scuff mark on the wall, black rubber, the shape of someone's shoe.

"Elizabeth, it's me. It's Ava. I just—I wanted to make sure you're okay."

She took another step. Another. The stairwell wound downward, each flight identical, the same gray walls and gray railings and gray floor, a space designed to be forgotten. The doors to each floor were solid metal with a single circular window, wire-reinforced glass showing slices of corridor beyond—white walls, passing figures, the normal world continuing as if nothing had happened.

She reached the first floor landing. The exit door was there, a push-bar, a red sign above it glowing EXIT. She checked the corner anyway, the narrow space behind the door, as if Elizabeth might have curled up there, as if this was all a game of hide-and-seek.

Empty.

Ava's chest tightened. She turned and looked up the stairwell, following the flights as they rose toward the upper floors, each landing a repetition of the one below. The light was the same at every level. The silence was the same.

"Elizabeth!" Louder now, the name carrying up the concrete shaft, bouncing off walls that didn't care.

Nothing.

Ava started climbing. Past the first floor, the second, the third. Each landing empty. Each door sealed. She pushed through the door on the third floor, the one that led to the ICU waiting room, and saw the backs of her own people through the small circular window—Sarah standing, Maggie sitting, Nathalie by the far window. No Elizabeth.

She let the door close and kept climbing.

Fourth floor. A mop bucket in the corner, the smell of bleach stronger here. Fifth floor. A wheelchair folded against the wall, its seat stained with something dark. Sixth floor. The door was propped open with a rubber wedge, and she could hear voices from inside—nurses, a distant intercom, the normal rhythm of a hospital at night.

She stopped. Bent over, hands on her knees, her breath coming in short white bursts in the cold air. She had climbed six floors. Her legs ached, the dancer's discipline keeping her upright when the rest of her wanted to fold.

No Elizabeth.

Ava straightened. She looked up the remaining flights, counted them in her head. The roof access would be through a door with an alarm. Elizabeth couldn't have gone up without triggering it, without someone noticing.

Which meant she had gone down.

Ava turned and started descending, faster now, taking the steps two at a time, her hand sliding along the railing. The sound of her footsteps echoed, a rapid drumbeat against the concrete. Past the sixth floor. The fifth. The fourth. The third. The second. The first.

The ground floor exit loomed ahead, the push-bar bright silver against the dark metal. She hit it with her palm, and the door swung open into a small vestibule, then a second door, and then she was outside.

The air hit her like a wall. Cold and damp, the particular chill of a city night that had settled into the concrete and the asphalt and the spaces between buildings. The parking lot stretched out before her, islands of orange light from the streetlamps, cars glinting under the glow. The hospital rose behind her, a massive dark shape studded with lit windows, each one a room where someone was being kept alive or letting go.

Ava stood in the small alcove outside the stairwell door, her breath misting in front of her face. She turned in a slow circle, scanning the immediate area. A bench. A trash can. A bicycle locked to a railing, its front wheel bent.

No Elizabeth.

She walked forward, her feet finding the asphalt, the cold seeping through the thin soles of her sneakers. The parking lot was mostly empty at this hour—a few cars scattered across the rows, the night shift staff's vehicles clustered near the emergency entrance. The security lights cast long shadows, stretching and distorting everything.

"Elizabeth!"

Her voice carried across the open space, absorbed by the cars and the darkness. No answer. No movement.

Ava pulled out her phone. The screen glowed, too bright in the darkness, and she scrolled to Elizabeth's contact. Pressed call. Held the phone to her ear.

It rang once. Twice. Three times.

Then she heard it.

A faint buzz, muffled, coming from somewhere to her left. Near the treeline that bordered the parking lot, where the orange light faded into shadow.

Ava walked toward the sound, her phone still pressed to her ear, the ringing continuing in her ear and in the darkness ahead. The buzz grew louder as she approached, more distinct, coming from a cluster of bushes at the edge of the parking lot.

She stopped at the treeline. The bushes were overgrown, thorny branches reaching out, the kind of scrub that grew in neglected spaces. Something glinted in the low light, caught on a branch.

Ava lowered her phone. Ended the call. The buzzing stopped.

She reached into the bush, careful of the thorns, her fingers brushing against wet leaves and deadwood until they found something smooth. Plastic. She pulled it out.

The phone was still warm. Elizabeth's phone, the screen showing her own missed call, the wallpaper a photo of Caleb sleeping, his face relaxed, the tension gone from his jaw. The case was plain black, scuffed at the corners, the kind of utilitarian choice that said I don't care what it looks like as long as it works.

Ava stared at it. The screen dimmed, then went dark.

She looked down at the bush. Something else was caught there—a silver glint, small. She reached in again, her fingers finding the object, pulling it free.

It was the earring. The small silver stud. Elizabeth's earring, the one she'd touched earlier, twisting it between her fingers while she stared at nothing. The clasp was broken, the metal bent as if it had been pulled free with force.

Ava's hand closed around it. The edges pressed into her palm, sharp and real.

She looked at the ground. The asphalt gave way to gravel here, the transition between parking lot and treeline marked by a strip of loose stones. There were marks in the gravel. Disturbances. A scuffed pattern that looked like someone had been dragged, their heels leaving furrows in the small stones.

Ava followed the marks with her eyes. They led from the edge of the parking lot toward a darker patch of shadow, where the treeline opened slightly, where a vehicle could have been parked. The tire tracks were visible in the dirt beyond the gravel—two parallel lines, the tread pattern clear, leading away into the darkness.

The car was gone.

Ava stood very still. The earring was cold in her hand. The phone was cold in her other hand. The night air pressed against her skin, damp and chill, and she could hear her own heartbeat in the silence, a drum that had been beating this whole time without her noticing.

She looked at the tire tracks again. Followed the direction they led, toward the road that bordered the hospital property, toward the city beyond. Toward anywhere.

Elizabeth had come down to the stairwell. She had left through the ground floor exit. She had walked—or been taken—to the edge of the parking lot.

And someone had been waiting.

Ava's mind was moving too fast and too slow at the same time, pieces of information colliding without forming a coherent picture. The empty propofol vial. The mercury in Caleb's IV. The twenty-minute gaps in observation. The stairwell door that no one had followed her through.

The earring in her hand, pulled free by force.

She turned and ran.

Back across the parking lot, her shoes slapping against the asphalt, the cold air tearing at her lungs. Past the bicycle, past the bench, through the vestibule, through the stairwell door, up the steps, her legs burning, her hand gripping the railing so hard that her knuckles ached. The earring was still in her grip, the sharp edges digging into her skin.

She burst through the door on the third floor, into the waiting room, and the fluorescent light hit her like a physical impact. Sarah looked up from her phone. Maggie rose from her chair. Nathalie turned from the window.

They saw her face. They saw the phone in her hand. They saw the earring.

"She's gone," Ava said. The words came out raw, scraped from somewhere deep. "Elizabeth is gone. Someone took her."

For a moment, no one moved. The words hung in the fluorescent air, suspended, refusing to settle into meaning. Ava watched Sarah's face shift—the slow processing, the rejection of what she'd heard, the forced acceptance as the reality of it pushed through.

"What do you mean, gone." Sarah's voice was flat. Not a question. A demand for correction.

Ava held up Elizabeth's phone. Then the earring, the silver stud catching the light, the bent clasp visible even from where Sarah stood. "I found these in the bushes at the edge of the parking lot. There were drag marks. Tire tracks leading away."

Sarah crossed the room in four steps. She took the phone from Ava's hand, turned it over, pressed the home button. The screen lit up—Caleb sleeping, his face soft, unaware. She stared at it for a long moment, and Ava saw something crack behind her eyes, something that had been holding steady for hours finally giving way.

"No." Sarah's voice was barely a whisper. "No, she just—she needed air. She said she needed a minute."

"She's not in the stairwell. She's not on any of the floors. I checked. I climbed to the sixth floor and came back down. The ground floor exit leads to the parking lot, and there's a bush there with her phone and her earring in it, and tire tracks leading away." Ava's voice was shaking now, the adrenaline ebbing, leaving something cold and hollow in its place. "Someone was waiting for her."

Maggie was already moving. She crossed to the window, her bare feet silent on the linoleum, and pressed her face to the glass, scanning the parking lot below. "I don't see anything. No cars pulling out. No movement."

"They're gone," Ava said. "The tracks are cold. This happened—I don't know—ten minutes ago. Maybe fifteen. While I was climbing stairs looking for her, someone was putting her in a car."

Nathalie had pulled out her phone. Her fingers moved rapidly across the screen, her face pale, her jaw set. "I'm calling hospital security. And the police. This is—" She stopped, swallowed. "This is a kidnapping. On hospital grounds. While she was visiting a patient who was just poisoned."

The word landed like a stone in still water. Poisoned. Kidnapped. The two events sat in the room together, connected by a thread that Ava could see but didn't want to name.

"They're connected," Maggie said, voicing the thing Ava had been trying not to think. "The mercury. The kidnapping. Someone is cleaning up loose ends."

Sarah's head snapped up. "Elizabeth isn't a loose end. She's—" She stopped. Her hand tightened around Elizabeth's phone, the screen going dark again, Caleb's sleeping face vanishing into black. "She's my friend. She's his girlfriend. She's one of us."

"I know." Maggie's voice was gentle, softer than Ava had heard it in days. "I know, Sarah. But someone tried to kill Caleb, and now someone has taken Elizabeth. That's not a coincidence. That's a pattern."

Sarah let out a breath that was almost a sob, but she caught it, forced it back down. She looked at the phone in her hand, then at the earring in Ava's. "The earring. You said the clasp was broken."

Ava nodded. She held it out, and Sarah took it, turning it over in her palm, her thumb tracing the bent metal.

"She wouldn't have taken it off voluntarily," Sarah said. "She never takes these off. She's had them since she was sixteen. They were her mother's."

The implication settled into the room. The earring hadn't fallen. It had been pulled. Torn free. In a struggle, or as a message, or as the only thing Elizabeth could leave behind.

Nathalie ended her call. "Security is locking down the hospital. Police are en route. They're going to want to talk to all of us."

"We need to see the security footage," Maggie said. "The parking lot cameras. The stairwell cameras. Anything that shows who came in and who went out."

"I already asked. They're pulling it now." Nathalie's phone buzzed in her hand, and she glanced at it, then looked up. "They want me in the security office. To identify anyone on the footage."

"Go." Sarah's voice had steadied, some of the hardness returning. "We'll hold the fort here. Call us as soon as you see anything."

Nathalie hesitated. Her gaze moved across the three of them—Ava, still holding the earring's ghost in her palm; Maggie, barefoot and collared, her cop's mind already working; Sarah, standing straight, her hand wrapped around Elizabeth's phone like a lifeline.

"I'll be back," Nathalie said. Then she was gone, the door swinging shut behind her, her footsteps receding down the corridor.

The room felt smaller without her. The silence pressed in, filled with everything none of them were saying.

Ava sat down. Her legs gave out, really, the adrenaline finally abandoning her, leaving her hollow and shaking. The vinyl chair caught her, cold through her jeans, and she pressed her palms flat against her thighs, trying to feel something solid.

Sarah sat beside her. Not close enough to touch, but close enough that Ava could feel the heat of her, the presence of another body in the same space.

"She was wearing her earrings," Sarah said, almost to herself. "When we left the house. I remember because she put them on in the car, twisting them into her ears while I was driving. She said she felt naked without them."

Ava didn't have words. She reached out instead, her hand finding Sarah's, their fingers interlacing. Sarah's grip was tight, almost painful, but Ava didn't pull away.

Maggie stood at the window, her back to them, her silhouette sharp against the orange glow of the parking lot lights. "I should have followed her."

"You couldn't have known," Ava said.

"I'm a cop. I'm supposed to know." Maggie's voice was raw. "I saw her leave. I saw the look on her face. And I let her go because I thought she needed space, because I thought the biggest danger in this hospital was already in a coma."

"We all thought that." Sarah's voice was quiet. "We were wrong."

The words hung in the air, heavy and final. Wrong. They had been wrong. About everything. About the safety of the hospital. About the idea that the danger was over. About the assumption that the worst had already happened.

Ava looked at the double doors that led to the ICU. Somewhere beyond them, Caleb was lying in a bed, his chest rising and falling with a machine's rhythm, his brain swimming in mercury and cold. He didn't know Elizabeth was gone. He didn't know someone had taken her. He didn't know anything at all.

And maybe that was a mercy. Or maybe it was the cruelest thing of all—that he would wake to a world where the woman who loved him had vanished into the night, leaving only an earring and a broken clasp as proof she had ever been there at all.

"We need to figure out who did this." Sarah's voice hardened. "Who had access to Caleb's room. Who knew Elizabeth was here. Who knew she would leave the waiting room alone."

Ava's mind caught on something. A detail, small, buried under the weight of everything else. She pulled it free, held it up to the light.

"The propofol vial," she said.

Sarah turned to look at her. "What about it?"

"It was in the house. In a drawer. Maggie found it." Ava's voice was slow, working through the logic as she spoke. "Whoever put mercury in Caleb's IV—they had to get into the hospital. They had to know which room he was in. They had to have access to his IV line."

"That could be anyone," Maggie said. "A nurse. A visitor. Someone who walked past the nursing station when no one was looking."

"But the propofol was in the house." Ava looked up, meeting Sarah's eyes. "Which means whoever did this has been in our space. Has been close enough to take things. Has been watching."

The room went very still.

Sarah's grip on Ava's hand tightened. "You're saying this isn't random. This isn't someone who saw an opportunity at the hospital."

"I'm saying someone knew where we lived. Knew what we kept in our drawers. Knew Caleb would be here tonight." Ava's voice dropped to a whisper. "And they knew Elizabeth would follow him."
