The first thing Elias knew was the light.

It was white and flat and very steady, the light of a room that never truly went dark, and it lay across his eyelids like a hand. He tried to turn his head away from it, and could not. Something heavy and warm pressed against his chest and shoulders and legs. A soft mechanical hum rose and fell beside his ear. Somewhere close by, at an even, unhurried pace, a machine was counting out the beats of a heart.

His heart. He was fairly sure it was his.

He opened his eyes.

The ceiling was made of pale acoustic tile. A fluorescent panel glowed above him, and beyond it a curtain of pale green fabric had been drawn halfway around a steel-railed bed. There was a window to his left, and through it a sky the color of dishwater, and a slow gray drizzle sliding down the glass. The room smelled of antiseptic and warm plastic and the faint, sweet staleness of too many sickrooms. A plastic bracelet circled his wrist. A line ran from the back of his left hand to a bag of clear fluid hung on a pole, and the bag had a small glowing band wrapped around it, like a warmer for a baby's bottle.

St. Jude. He knew it by the smell. He had brought enough bodies out of this building to recognize the corridors in his sleep.

He lay still and took inventory.

The cold was still in him. It had not gone, but it had changed, from a hard bright blade to a dull, deep ache that seemed to live in the very center of his bones. Above it lay a great soft weight, and he understood after a moment that it was a blanket, a vast inflated thing, hissing gently with warm air. It covered him to the chin. It was the most comfortable thing he had ever felt, and he hated it on principle.

His hands.

He lifted his right one from the sheet. It came up slowly, heavy as lead, and the drip line pulled at his other wrist. He held it in front of his face.

It was wearing a glove.

Black leather, supple and snug, stitched along the seams. The cuff was pressed flat against his wrist. He turned his hand over, and looked at the palm, and then at the back, and then, with a slow cold twist of the stomach, at the left. The same. A black leather glove, lying neatly on the sheet where the drip line pulled at it, the cuff smoothed flat.

Smoothed flat.

He stared at it.

He knew how he did it himself. He drew the glove on, and pinched the cuff between thumb and forefinger at the center of the wrist, and ran the pad of his thumb from the center outward, once to the left and once to the right, pressing the leather flat against the skin. It was a small private habit, a tic of fifteen years. He had never been taught it. He had never seen anyone else do it. He had never, as far as he knew, been watched while he did it.

But the cuffs on both gloves had been smoothed in exactly that way.

"Oh, good," said a cheerful voice. "You're up."

A nurse was standing at the foot of the bed with a clipboard in one hand. She was a stocky woman in her fifties, with cropped gray hair and a pair of reading glasses pushed up into it, and she wore the unhurried, faintly amused expression of someone who had been dealing with the ill and the frightened since before Elias was born. Her name tag read INES.

"Don't try to sit up," she said. "You'll feel like you've been hit by a truck. Core temp was ninety-one point eight when they brought you in, and we've been pumping warm air and warm saline into you since about four a.m. You're up to ninety-six, which is a miracle, because for a while there I didn't think you'd go above ninety-three." She checked a number on the monitor, and wrote it down. "Mild to moderate hypothermia. In a heated building. In October. The resident's been scratching his head over it for three hours."

"How long," said Elias. His voice was a dry croak.

"It's a quarter past seven. Saturday morning." She stepped around the bed, and poured water from a plastic pitcher into a cup, and held it out to him with a bent straw. "Drink. Small sips."

He drank. It was the best water of his life.

"What happened to me?"

"That's what I'd like to know." Ines took the cup back. She tilted her head. "Your coworker found you on the floor of the morgue around three. Big skinny kid, nice manners, about ready to faint himself. He'd gone back for his phone and there you were, out cold, blue around the mouth." She shook her head. "Said you were alone, door locked, nothing out of place. You've got no injuries, no signs of a struggle, no drugs on the tox screen. Just a body that decided to forget how to keep itself warm."

"The door was locked."

"That's what he said." A pause. "He said the captain's car was already parked at the curb when he got there, and the doors were standing open. Said he figured the captain must have had a key."

Elias did not say anything.

"Your captain's a funny one," said Ines, and her voice changed a little, dropped a note, lost some of its practiced briskness. "I've been at this twenty-four years. I've had cops sit with their partners. I've had cops sit with their mothers. I've never had one put a patient's gloves back on him."

"I beg your pardon?"

"Your gloves. Didn't you notice?" She nodded at his hands. "The paramedics wanted to cut them off you in the ambulance, for the hypothermia protocol. Standard procedure. Your captain wouldn't let them. He stopped them with one hand, real quiet, like he was asking them to hold a door." She smiled faintly. "He put on a pair of exam gloves himself, and he drew your gloves back on, one at a time. Very careful. Smoothed the cuffs. Said you'd want them on."

The hum of the warming blanket filled the room.

"He said that?"

"In those words. I was standing right there." Ines studied him for a moment. "I don't know what your story is, honey, and it's none of my business. But a man doesn't do that for just anybody. You might want to be nice to him."

She patted the blanket once, briskly, and left. The curtain swung shut behind her, and the light slid across the bed like water.

Elias lay still.

He looked at his hands. They were the same hands, in the same gloves. They lay on the sheet like two small black animals, perfectly calm. He thought: he saw my bare hand. He thought: he saw it, and he knew what it meant, and he did not ask. He put on rubber gloves so as not to touch the skin, and he drew the leather back over it, and smoothed the cuffs flat.

How did he know how I do it?

It was not a question that had an answer he could stand to look at. He pushed it down. He took a long, slow breath, and let his eyes travel around the room, past the window and the drip stand and the pale green curtain, to the far corner by the door.

There was a chair there. It was a low vinyl thing, the kind they provided for visiting relatives, with a wipe-clean seat and a cracked arm. A man sat in it.

He had not moved. That was why Elias had not seen him.

He was sitting very still, with his back straight and his hands resting on his knees. His head was tipped slightly against the wall. His eyes were closed. He had taken off his jacket, and it lay folded across his lap, and Elias saw with a cold, slow drop of the heart what it was.

Black. Waxed canvas. The rain had dried on it in pale streaks.

His pulse jumped.

It was a small, sharp, shameful thing, and the monitor beside his bed took note of it at once. The steady green line broke into a stutter. The soft beep beside his ear quickened, went double, went triple, and he lay rigid under the vast hissing blanket with his eyes wide open and his hands locked in their gloves.

The man in the chair opened his eyes.

For a long moment neither of them moved.

Luke Harrow looked the way a man looks who has been in one place a very long time. His hair was rumpled. A day's growth of dark stubble shadowed his jaw. His shirt was creased across the chest and open at the collar, and there was a stain of old coffee on one cuff. His eyes were red-rimmed, and underneath them lay a smudge of violet that made him look younger, and more tired, and much less like a man who could have stood on a rainy pier and cut a throat.

And yet it was the same face. The same brow, the same mouth, the same steady dark eyes. It had been lit by a passing headlamp on the far side of a dying man's last breath, and Elias had seen it, and he could not now see anything else.

"You are awake," said Harrow.

His voice was hoarse. It was low, and quiet, and absolutely without alarm.

Elias did not answer. He could not. The monitor beeped on, high and quick and humiliating, and Harrow's gaze went to it, and then back to Elias's face.

"Your pulse is high," he said. "I will stay here."

He did not stand. He did not move at all, except to fold the black jacket over the arm of the chair with slow, deliberate care, so that the waxed side lay face-down against the vinyl. Then he laid his hands flat on his knees again, in plain sight, open, and sat there like a man who has learned how to be still in the presence of a frightened animal.

"I will not come closer unless you ask me to," he said. "I want you to know that."

The words were simple. They were kind. They were exactly the words Elias would have chosen, if he had been given the chance to choose. And the fact that they were exactly right, so finely tuned to his worst fear, felt like a hand laid against the back of his neck.

"What happened?" said Elias. His own voice came out very thin.

"You collapsed in the lab. Wade found you at three. I arrived with the ambulance."

It was a smooth answer, and it was not true. Elias was quite sure of it. He had heard the footsteps. He had smelled the cedar. He had been alone in a locked room for over an hour when the doors opened and a shape crossed the floor toward him, and it had not come with any ambulance.

He looked at Harrow. Harrow looked back.

There it was. The silence between them was taut as a wire. Neither of them spoke. Elias saw, with an odd clear detachment, that the captain knew precisely what he had just said, and knew that Elias knew it, and was offering the lie anyway, like a coat held out, on the understanding that it would be taken or refused without comment.

"The doctors tell me your core temperature was ninety-one point eight," said Harrow at last. "They were concerned. They asked me a number of questions. I did not tell them anything."

"Anything about what?"

"About what I do not know." A faint, tired smile flickered at the corner of his mouth. "It was not mine to tell."

The words landed very quietly.

Elias lay with his eyes on the ceiling. He felt the blood ticking in his wrists. It was not mine to tell. It was a perfectly ordinary thing to say. A man did not go volunteering another man's medical history. But Harrow had said it with a weight, and a pause, and the word mine had been very slightly pressed, like a thumb on a bruise.

"My notes," he said.

"In your bag. Wade brought it over. It is under your bed."

"Did you read them?"

There was a pause. It was a very small one.

"No," said Harrow.

Elias turned his head on the pillow and looked at him. He looked for a long time, searching the tired face for some flicker of evasion, some tightening of the jaw, some change in the eyes. He was a pathologist. He had spent twelve years learning to read what people's bodies told him when their mouths were closed. He saw nothing. Only exhaustion, and patience, and a steady, open, unreadable gaze.

He could not tell.

It was the worst thing he had ever felt. He could not tell if the man was lying.

The monitor had begun to slow. It was dropping, beat by beat, from its wild stutter to something closer to a walk. He hated it. He hated the way his body kept betraying him, the way it kept leaning toward the thing he feared. He shifted under the blanket, and the movement sent a fresh shiver through him, bone-deep and helpless, and he clenched his teeth to stop it.

"You are still cold," said Harrow quietly.

"I am perfectly..."

"Your lips are blue." It was not an accusation. "Your hands have been shaking since you woke. They cannot warm you past ninety-six. The resident says it is not a condition he has seen before." He paused. "I do not think it is one anyone has."

Elias said nothing.

"May I?"

It was the smallest word. It was hardly a word at all. It hung in the air between them like a thread spun from one side of a chasm to the other, and Elias looked at it, and did not know what to do.

Harrow had not moved. He sat in the plastic chair with his hands open on his knees, and his face was utterly still. He had put out no hand. He had taken no step. He was waiting, with the terrible patience of a man who would wait all day, and all night, and all the days after that.

And there was a thing beneath his patience that Elias had never seen on anyone's face. It was not triumph. It was not hunger. It was a long, quiet, aching fear.

Not of being refused. Of being accepted.

Elias did not understand it. He only knew that he was frightened, and freezing, and more tired than he had ever been. That he had seen this man's face in the last light of a dying man's eyes. That the same hands resting on those knees had held a knife. That the same voice that asked may I had said it is almost over to a man on his knees in the rain.

He knew all of it. And he knew, too, that he was so cold that his bones hurt, and that nobody had held his hand in twelve years.

He did not say yes.

He did not say no.

He looked at Harrow, and Harrow looked at him, and something passed between them that had nothing to do with words.

The captain rose.

He came across the room slowly. He did not crowd the bed. He stopped at its side, near the window, a little below the level of Elias's shoulder, and lowered himself into a crouch so that his eyes were on a level with Elias's own. His face in the gray light was very close now. There were fine lines at the corners of his eyes. A small white scar ran through his left eyebrow.

He held out both hands, palm up.

He did not touch anything. He held them in the air between them, open and empty, scarred across the knuckles, and waited.

Elias looked at those hands for a very long time.

Then, slowly, he lifted his right hand from the sheet. It felt like lifting a stone. The drip line pulled at his wrist. He held it in the air for a moment, black and small and trembling, and then he laid it in Harrow's.

The captain's fingers closed over it.

They were so warm.

That was the first thing. Warmth came through the leather, slow and steady and enormous, like a tide coming up a beach. It did not burn. It simply arrived, and settled, and stayed. Harrow's other hand came over the top, and cupped it, and the two of them lay around Elias's gloved fingers like a shell around a pearl, and the warmth went into him and began, for the first time in a day and a night and a lifetime, to reach the place where the cold lived.

Luke.

The name rose in him without asking. It was gentle, and inevitable, and it frightened him more than anything he had seen on that pier. Luke's hands around his. Luke's thumb moving once, very slightly, across the knuckles of the glove, and then going still.

The monitor beside the bed had slowed. The beeps came far apart now. Steady. Even. The pulse of a man who had decided, in some place below reasoning, to let himself be held.

He did not look at Harrow's face. He did not dare. He kept his eyes on the two hands around his own, and breathed, and the room was very quiet, and rain ran down the window.

He hated it.

He hated that it was the only thing that had helped. He hated that it had taken a murderer to make the cold go quiet. He hated that the hands wrapped around his were the same hands that had lowered a dying man to the boards as gently as a sleeping child, and that some lost part of him had looked at that gentleness in the last light of a dead man's eyes and thought, even then, even as it watched a throat open: he is being careful of him.

He did not squeeze back.

But he did not let go.

The moments passed, and neither of them spoke. Somewhere in the corridor a cart rattled by. A voice called a name. The first real light of the day came in pale through the window and lay across the blanket and the gray wall and the two joined hands, and on the far side of the glass the drizzle thinned to nothing, and the city began slowly to wake.

"Rest," said Luke Harrow, very softly. "I am not going anywhere."

Elias closed his eyes.

He did not sleep. He lay there, in the warm hissing dark, with his hand held in the hand of the man who had killed five people, and thought of a dying councilman on a wet pier, and a name said aloud in the dark, and a single whispered answer.

Yes.

He would have to decide. He knew that. He could say it now, in the light, with a nurse twenty feet away and the whole machinery of a hospital at his back. He could say: I saw your face. He could say it, and they would come, and they would take Luke Harrow away in handcuffs, and the truth about a fire on a hill would go with him into the ground.

He did not say it.

He lay with his eyes shut, and his hand in a stranger's, and listened to the rain.
