"No, thanks."

He was neatly dressed, in a jacket and tie, but his wig, the black wig, threw her off. Also his eyes: they were tired, distant - the eyes of a man near the breaking point of fatigue. She remembered how the rats had collapsed from excessive pleasurable stimulation. Eventually they lay spread-eagled on the floor of the cage, panting, too weak to crawl forward and press the shock lever one more time.

"Are you alone here?" he said.

"Yes, I am."

There was a small bruise on his left cheek, just below the eye. She looked at his bandages. They just barely showed, a bit of white between the bottom of his wig and the top of his collar.

"Is something wrong?" he asked.

"No, nothing."

"You seem tense." His voice sounded genuinely concerned. Probably he'd just had a stimulation. She remembered how he had become sexually interested in her after the test stimulations, just before he was interfaced.

"No… I'm not tense." She smiled.

"You have a very nice smile," he said.

She glanced at his clothes, looking for blood. The girl had been soaked; Benson must have been covered with blood, yet there was none on his clothes. Perhaps he'd dressed after taking a second shower. After killing her.

"Well," she said, "I'm going to have some coffee." She went into the kitchen with a kind of relief. It was somehow easier to breathe in the kitchen, away from him. She put the kettle on the burner, turned on the gas, and stayed there a moment. She had to get control of herself. She had to get control of the situation.

The odd thing was that while she had been shocked to see him suddenly in her apartment, she was not really surprised that he had come. Some psychomotor epileptics feared their own violence.

But why hadn't he returned to the hospital?

She went out to the living room. Benson was standing by the large windows, looking out over the city, which stretched away for miles in every direction.

"Are you angry with me?" he said.

"Angry? Why?"

"Because I ran away."

"Why did you run away, Harry?" As she spoke, she felt her strength coming back, her control. She could handle this man. It was her job. She'd been alone with men more dangerous than this. She remembered a six-month period at Cameron State Hospital, where she had worked with psychopaths and multiple murderers - charming, engaging, chilling men.

"Why? Because." He smiled, and sat down in a chair. He wriggled around in it, then stood up, sitting down again on the sofa. "All your furniture is so uncomfortable. How can you live in such an uncomfortable place?"

"I like it."

"But it's uncomfortable." He stared at her, a faint challenge in the look. She wished again that they were not meeting here. This environment was too threatening, and Benson reacted to threats with attack.

"How did you find me, Harry?"

"You're surprised I knew where you lived?"

"Yes, a little."

"I was careful," he said. "Before I went into the hospital, I found out where you lived, where Ellis lived, where McPherson lived. I found out where everybody lived."

"Why?"

"Just in case."

"What were you expecting?"

He didn't reply. Instead, he got up and walked to the windows, looked out over the city. "They're searching for me out there," he said. "Aren't they?"

"Yes."

"But they'll never find me. The city is too big."

From the kitchen, her kettle began to whistle. She excused herself and went in to make coffee. Her eyes scanned the counter, searching for something heavy. Perhaps she could hit him over the head. Ellis would never forgive her, but-

"You have a picture on your wall," Benson called. "A lot of numbers. Who did that?"

"A man named Johns."

"Why would a man draw numbers? Numbers are for machines." She stirred the instant coffee, poured in milk, went back out and sat down.

"Harry…"

"No, I mean it. And look at this. What is this supposed to mean?" He tapped another picture with his knuckles.

"Harry, come and sit down."

He stared at her for a moment, then came over and sat on the couch opposite her. He seemed tense, but a moment later smiled in a relaxed way. For an instant, his pupils dilated. Another stimulation, she thought.

What the hell was she going to do?

"Harry," she said, "what happened?"

"I don't know," he said, still relaxed.

"You left the hospital…"

"Yes, I left the hospital wearing one of those white suits. I figured it all out. Angela picked me up."

"And then?"

"And then we went to my house. I was quite tense."

"Why were you tense?"

"Well, you see, I know how this is all going to end."

She wasn't sure what he was referring to. "How is it going to end?"

"And after we left my house, we went to her apartment, and we had some drinks, and we made love, and then I told her how it was going to end. That was when she got scared. She wanted to call the hospital, to tell them where I was…" He stared off into space, momentarily confused. She didn't want to press the point. He had had a seizure and he would not remember killing the girl. His amnesia would be total and genuine.

But she wanted to keep him talking. "Why did you leave the hospital, Harry?"

"It was in the afternoon," he said, turning to look at her. "I was lying in bed in the afternoon, and I suddenly realized that everybody was taking care of me, taking care, servicing me, like a machine. I was afraid of that all along."

In some distant, detached, and academic corner of her mind, she felt that a suspicion was confirmed. Benson's paranoia about machines was, at bottom, a fear of dependency, of losing self-reliance. He was quite literally telling the truth when he said he was afraid of being taken care of. And people usually hated what they feared.

But then Benson was dependent on her. And how would he react to that?

"You people lied to me," he said suddenly.

"Nobody lied to you, Harry."

He began to get angry. "Yes, you did, you- " He broke off and smiled again. The pupils were briefly larger: another stimulation. They were very close now. He'd tip over again soon.

"You know something? That's the most wonderful feeling in the world," he said.

"What feeling?"

"That buzz."

"Is that how it feels?"

"As soon as things start to get black - buzz! - and I'm happy again," Benson said. "Beautifully warm and happy."

"The stimulations," she said.

She resisted the impulse to look at her watch. What did it matter? Anders had said he would be coming in twenty minutes, but anything could delay him. And even if he came, she wondered if he could handle Benson. A psychomotor epileptic out of control was an awesome thing. Anders would probably end up shooting Benson, or trying to. And she didn't want that.

"But you know what else?" Benson said. "The buzz is only nice occasionally. When it gets too heavy, it's… suffocating."

"Is it getting heavy now?"

"Yes," he said. And he smiled.

In that moment when he smiled, she was stunned into the full realization of her own helplessness. Everything she had been taught about controlling patients, everything about directing the flow of thought, about watching the speech patterns, was useless here. Verbal maneuvers would not work, would not help her - any more than they would help control a rabies victim, or a person with a brain tumor. Benson had a physical problem. He was in the grip of a machine that was inexorably, flawlessly pushing him toward a seizure. Talk couldn't turn off the implanted computer.

There was only one thing she could do, and that was get him to the hospital. How? She tried an appeal to his intellectual functions. "Do you understand what's happening, Harry? The stimulations are overloading you, pushing you into seizures."

"The feeling is nice."

"But you said yourself it's not always nice."

"No, not always."

"Well, don't you want to have that corrected?"

He paused a moment. "Corrected?"

"Fixed. Changed so that you don't have seizures any more." She had to choose her words carefully.

"You think I need to be fixed?" His words reminded her of

Ellis: the surgeon's pet phrase.

"Harry, we can make you feel better."

"I feel fine, Dr. Ross."

"But, Harry, when you went to Angela's- "

"I don't remember anything about that."

"You went there after you left the hospital."

"I don't remember anything. Memory tapes are all erased. Nothing but static. You can put it on audio if you want, and listen to it yourself." He opened his mouth, and made a hissing sound. "See? Just static."

"You're not a machine, Harry," she said softly.

"Not yet."

Her stomach churned. She was physically sick with tension. Again that detached part of her mind noted the interesting physical manifestation of an emotional state. She was grateful for the detachment, even for a few instants of it.

But she was also angry at the thought of Ellis and McPherson, and all those conferences when she had argued that implanting machinery into Benson would exaggerate his pre-existing delusional state. They hadn't paid any attention.

She wished they were here now.

"You're trying to make me into a machine," he said. "You all are. I'm fighting you."

"Harry- "

"Let me finish." His face was taut; abruptly, it loosened into a smile.

Another stimulation. They were coming only minutes apart now. Where was Anders? Where was anybody? Should she run out into the hall screaming? Should she try to call the hospital? The police?

"It feels so good," Benson said, still smiling. "That feeling, it feels so good. Nothing feels as good as that. I could just swim in that feeling forever and ever."

"Harry. I want you to try and relax."

"I'm relaxed. But that's not what you really want, is it?"

"What do I want?"
