4 A.M.

Room One is eleven feet by nine.

I know because I measured it, many years ago, on my first visit to the department, with the idle precision of a man who cannot enter a room without counting its corners. It has a steel table bolted to the floor, two chairs, a mirror that is not a mirror, and a ceiling light behind a wire cage that has never, to my knowledge, been switched off. The walls are a color I cannot name. It is the color of a thing that has been washed too often.

Arlo Wren was sitting in the far chair with his hands on the table.

They had cuffed him in front, which I thought was a kindness, and attached the chain to a ring in the steel. He had been given a gray blanket. He had put it round his shoulders, and it made him look like a child at a bus stop. His hair was still wet from the rain. There was a small plastic bag on the table in front of him, with a strip of red tape across the seal, and inside it, crushed and discolored, a flat yellow thing the size of a thumb.

He did not look up when I came in.

"Dr. Vaughn," he said.

It was the voice from the telephone. Low and hoarse, a little flat. It was only a voice. Without the distortion, without the dark, it had nothing in it that frightened anyone. It was the voice of a man who works nights in a library.

"Mr. Wren."

"Please." The corner of his mouth moved. "Arlo."

I sat down.

…

I will tell you what I saw, because it is my profession to see, and because I have found that the first thirty seconds in a room tell you nearly everything that will happen in the next six hours.

He was twenty-six. He sat very straight, with his shoulders drawn back and his chin level, in the posture of a boy who has been taught to sit so by a woman with a ruler. His hands lay quietly on the steel, long, white, delicate hands, palms down. His nails were clean. There was a faint tremor in them, fine and fast, which I put at nine to ten cycles in every second, and which he had not tried to hide.

He was tired beyond measure. There were bruise-colored hollows under his eyes. But they were clear, and steady, and entirely present. They looked at me with an expression I had seen only in the very sick, or the very old: an expression of enormous mildness, as if nothing in the world could now surprise or injure him.

I knew then.

I could not have said what I knew. It was nothing I could put into a sentence. It was a pattern, like the pattern of a face glimpsed in a crowd; and I put it aside, because I had a duty to the thing I had come to do, and because I wanted, God help me, to hear him.

"Before we begin," said Arlo Wren, "I'd like to say something."

"Please."

"I'm not going to lie to you."

"Everyone says that."

"Yes." He considered it. "That's true. But I've not got any reason to. It's a strange thing. I've been lying for so long. For fifteen years I never said a true thing out loud, and now I find I've nothing left to protect." He lifted one shoulder. "It's rather restful."

…

I turned on the recorder. I stated the date and the hour, and the names of those present, and I told him his rights, though it was not my place, and he nodded at each one with grave attention. He declined a lawyer. He said he would like some water. A uniformed officer brought him a paper cup, and he drank it in three slow swallows, with the chain chinking on the table, and then he set it down very exactly in the center of the ring it had left.

"Tell me about Sunflower House," I said.

And he did.

I shall not give it all. It runs to eleven thousand words in the transcript, and the transcript is a public record now, and anyone may read it. But I shall tell you the shape of it, because the shape is what mattered.

He told me about the carrier bag. He told me about the winter, and the radiators that clanked in the night, and Mrs. Penhallow with her ring of keys. He told me about the library, which was a cupboard, and the encyclopedia in twenty-six volumes with a missing Q. He told me about a day in his seventh year when a small blind girl had come to the home in a gray coat with a label sewn in the collar, and sat down on the bench beside him in the refectory, and said, in a voice like a bell, Is someone there?

"I said yes," said Arlo. "That's all. I said, 'Yes. I'm here.'"

His voice did not break. It was perfectly level. He told it as one tells a story about someone else.

"She asked me to describe the room. So I did. I said it had a brown floor and a high ceiling and forty-one tables. I'd counted them." His mouth moved. "She said, 'You're very good at that.' Nobody'd ever said so."

"And the knocks?"

"The pipes." He nodded. "We slept on opposite sides of a wall. She'd tap, and I'd tap back. Three slow. It meant I'm here. It meant good night. It meant a lot of things." He paused. "It meant everything, really. At that age."

…

I let him go on for an hour.

I did not interrupt. I have learned, over a long life of listening to the guilty, that the worst mistake is to rush the one thing that matters. It will come. It comes of itself, if one waits, as a bubble comes to the top of a pond. He told me about the money, and the boys at the school, and the long years of study. He told me how he had learned to build a machine from a handful of old textbooks and a donated terminal. He told me about Magnus Kane, whom he had never met, and whose pen he had followed; he told me about Hollis, and about a certain boarding house on a certain Tuesday. He told me about the first room. It was calm. It was dispassionate. It was as if he were reading the minutes of someone else's meeting.

I listened. I watched his hands.

At twenty minutes past two the left thumb began to move.

He did not know it. It stroked, slowly, along the side of the first finger, back and forth. Three slow, one pause. Three slow, one pause. It was the old rhythm, the pipe rhythm, and it was quite involuntary, and it had begun at the instant he said the word October.

I wrote it down. I wrote: thumb, 3/1.

"Arlo," I said.

"Yes."

"The twenty-third of October."

"Yes."

"Tell me what you did."

…

He was silent for a long time.

The light buzzed in its cage. Somewhere beyond the wall, a telephone rang four times and stopped. I heard the faint tick of the clock above the door. It said ten to three.

"I told you," said Arlo. "I was in the infirmary."

"You told the police that."

"Yes."

"Did you tell me the truth?"

He raised his eyes.

They were very dark. They were deep, tired, immensely gentle. He held my gaze, and I saw in them neither anger nor fear, nor even grief, only a sort of grave acknowledgment, such as passes between two men who have been walking in the same direction for a long time and have just arrived.

"No," he said.

I said nothing.

"I woke at a quarter past eight. I heard the dogs." He said it flatly. "I knew what it was. I think I'd known for a week. They'd said things at dinner. The tall boy, Dominic, had looked at her. He'd smiled." His voice remained quite level. "I got out of bed. I had a fever, and the floor was cold, and I couldn't find my slippers. I went down the back stairs in my nightshirt. I came out by the laundry door, and went round the end of the coal shed, and I saw them."

"How many?"

"Five of them." He considered. "And Mr. Ferris, the caretaker. They were on the steps. They were laughing. One of them had a cigarette, and they were passing it round."

"Where was Stella?"

"In there." His voice dropped. "They'd shut the door. I could hear her. I could hear the dogs on the other side of the iron, and her, and she was—" He stopped.

I waited.

"She was calling for me," said Arlo.

…

It is a strange thing to hear a confession.

I have heard perhaps two hundred. I have heard them in cells, in hospitals, in bars, in the back of cars. I have heard men weep and laugh and boast and curse. I have never grown used to it. It is a moment when a human being, of his own will, takes off all his clothes. And the thing one feels, if one is honest, is not satisfaction. It is a kind of horror, and a kind of love.

"I didn't move," said Arlo.

"No."

"I stood behind the shed with my hands over my mouth. I was shaking so hard that my teeth knocked. I thought: they'll hear me. I thought: they'll put me in there too." He drew breath. "And she kept saying my name. She said it forty or fifty times. And I thought, I'll go. I'll go in a minute. I'll count to ten. And then I'd count to ten, and I couldn't."

His left thumb had stopped.

"Something fell. I heard it. It hit the gravel by my foot. It was her clip, with the flower. It had come off when they dragged her." He lifted his chained hands a little and looked at the bag. "I picked it up. I don't know why. I held it in my fist. It was wet. And then one of them looked round, and I ran."

"Back to your bed."

"Back to my bed." He smiled, faintly, terribly. "I pulled the blanket over my head. I put my fingers in my ears. I lay there until it was light. And in the morning they said she'd died of her heart. And Mrs. Penhallow said, crying, Poor lamb, I hope it was quick."

He looked at me.

"It wasn't quick," he said. "It was four hours. I counted. I counted everything. That's what I do."

…

I did not speak.

I had a speech prepared. I had had it for days. It was good: tender, and exact, and not at all sentimental. It dealt with the incapacity of children, and the nature of fear, and the injustice of a guilt that has no proper object. I had rehearsed it in the lift. I had meant to say, You were eleven.

I looked at him, and I could not say it.

"I used to think that if I made it right," said Arlo, "if I made enough of them feel it—the dark, and the dogs, and the door—then it would add up. You see? A sum. Four rooms, and five of them, and then it would balance. And I'd be able to stop counting." He shook his head. "But it doesn't. It never comes out. There's always a remainder. And the remainder is always me."

"Arlo—"

"It's all right." He gave a small cough, as one does to clear the throat. "I knew it wouldn't, you know. I only wanted it to be done properly. I wanted someone to see it was done properly. And then you said my name in front of everyone, and I thought: oh, there he is. There's the person I've been waiting for."

He coughed again.

I saw it, and I did not understand it. I saw the first small shake of the shoulders, the hand lifting to the mouth. I saw him turn away. I saw the cuffs rattle. The second cough was harder and deeper, with a dry harsh rasp at the bottom, and when he took his hand from his mouth there was a faint dark smear across the knuckles.

It was thin. It was almost black.

…

"Arlo."

"It's nothing."

"What did you do?"

He looked at his hand. He turned it over, and looked at the smear, with an expression of mild interest. "Oh, that," he said. "That'll be the liver, I think. It starts there. The sclera go yellow first, and then there's a pain here." He touched his right side below the ribs. "You'd have seen it, if you'd looked. You're very observant. But you were busy."

The room was quite silent.

"What have you taken?"

"Yesterday morning. Four o'clock. Before I turned on the stream." He said it quite gently. "I wanted to be certain of the timing. I'd calculated that I'd have about a day and a half. Long enough to finish. Not so long as to be a bother." He glanced at the clock. "It's ten to four. So that's about twenty-four hours. I make it a little short of that. I'm sorry."

"What is it?"

"It doesn't matter."

"Arlo, what is it?"

"There isn't an antidote." He smiled at me, kindly, as one does at a child who has asked a foolish question. "I made quite sure. I'm good at that. It's not as though I'd leave a loophole."

I was on my feet.

I do not remember rising. The chair had gone over behind me, and I had my hand on the steel of the table. I was shouting. I was shouting for Leo, for a doctor, for anyone, with the full force of my lungs, and the door burst inward, and the uniformed officer was there with his mouth open, and Leo behind him, gray and wild.

"Medics," I said. "Now. He has taken something. He has taken something, a poison, twenty-four hours ago, and he will not tell me—"

"Atticus," said Arlo.

His voice was very soft. I turned.

He had lifted the plastic bag with both bound hands, and was holding it against his chest, just below the throat. His eyes were closed. His face was perfectly calm.

"It's four in the morning," he said. "It's all right. You can stop now. You did it properly."

On the wall above the door, the red hand of the clock touched twelve.
