"When did he leave?"

"Just a few minutes ago."

"How long have you been here?"

"About a week," the girl in the pool said. "Harry invited us to stay. He thought we were cute."

The other girl wrapped the towel around her shoulders and said, "We met him at the Jackrabbit. He comes there a lot."

Ross nodded.

"He's a lot of fun," the girl said. "A lot of laughs. You know what he was wearing tonight?"

"What?"

"A hospital uniform. All white." She shook her head. "What a riot."

"Did you talk to him?"

"Sure."

"What did he say?"

The girl in the red bikini started back inside the house. Ross followed her. "He said not to tell the cops. He said to have a good time."

"Why did he come here?"

"He had to pick up some stuff."

"What stuff?"

"Some stuff from his study."

"Where is the study?"

"I'll show you."

She led her back into the house, through the living room. Her wet feet left small pools on the bare hardwood floor.

"Isn't this place wild? Harry's really crazy. You ever heard him talk about things?"

"Yes."

"Then you know. He's really nutty." She gestured around the room. "All this old stuff. Why do you want to see him?"

"He's sick," Ross said.

"He must be," the girl said. "I saw those bandages. What was he, in an accident?"

"He had an operation."

"No kidding. In a hospital?"

"Yes."

"No kidding."

They went through the living room and down a corridor toward the bedrooms. The girl turned right into one room, which was a study - antique desk, antique lamps, overstuffed couches. "He came in here and got some stuff."

"Did you see what he got?"

"We didn't really pay much attention. But he took some big rolls of paper." She gestured with her hands. "Real big. They looked like blueprints or something."

"Blueprints?"

"Well, they were blue on the inside of the roll, and white on the outside, and they were big." She shrugged.

"Did he take anything else?"

"Yeah. A metal box."

"What kind of a metal box?" Ross was thinking of a lunchbox, or a small suitcase.

"It looked like a tool kit, maybe. I saw it open for a moment, before he closed it. It seemed to have tools and stuff inside."

"Did you notice anything in particular?"

The girl was silent then. She bit her lip. "Well, I didn't really see, but…"

"Yes?"

"It looked like he had a gun in there."

"Did he say where he was going?"

"No."

"Did he give any clue?"

"No."

"Did he say he was coming back?"

"Well, that was funny," the girl said. "He kissed me, and he kissed Suzie, and he said to have a good time, and he said not to tell the cops. And he said he didn't think he'd be seeing us again." She shook her head. "It was funny. But you know how Harry is."

"Yes," Ross said. "I know how Harry is." She looked at her watch, it was 1:47. There were only four hours left.

The first thing that Ellis noticed was the smell: hot, damp, fetid - a dark warm animal smell. He wrinkled his nose in distaste. How could Benson tolerate a place like this?

He watched as the spotlight swung through the darkness and came to rest on a pair of long tapering thighs. There was an expectant rustling in the audience. It reminded Ellis of his days in the Navy, stationed in Baltimore. That was the last time he had been in a place like this, hot and sticky with fantasies and frustrations. That had been a long time ago. It was a shock to think how fast the time had passed.

"Yes, ladies and gentlemen, the incredible, the lovely, Cynthia Sin-cere. A big hand for the lovely Cynthia!"

The spotlight widened onstage, to show a rather ugly but spectacularly constructed girl. The band began to play. When the spotlight was wide enough to hit Cynthia's eyes, she squinted and began an awkward dance. She paid no attention to the music, but nobody seemed to mind. Ellis looked at the audience. There were a lot of men here - and a lot of very tough-looking girls with short hair.

"Harry Benson?" the manager said, at his elbow. "Yeah, he comes in a lot."

"Have you seen him lately?"

"I don't know about lately," the manager said. He coughed. Ellis smelled sweet alcoholic breath. "But I tell you," the manager said, "I wish he wouldn't hang around, you know? I think he's a little nuts. And always bothering the girls. You know how hard it is to keep the girls? Fucking murder, that's what it is."

Ellis nodded, and scanned the audience. Benson had probably changed clothes; certainly he wouldn't be wearing an orderly's uniform any more. Ellis looked at the backs of the heads, at the area between hairline and shirt collar. He looked for a white bandage. He saw none.

"But you haven't seen him lately?"

"No," the manager said, shaking his head. "Not for a week or so." A waitress went by wearing a rabbitlike white fur bikini. "Sal, you seen Harry lately?"

"He's usually around," she said vaguely, and wandered off with a tray of drinks.

"I wish he wouldn't hang around, bothering the girls," the manager said, and coughed again, sweetly.

Ellis moved deeper into the club. The spotlight swung through smoky air over his head, following the movements of the girl on stage. She was having trouble unhooking her bra. She did a sort of two-step shuffle, hands behind her back, eyes looking vacantly out at the audience. Ellis understood, watching her, why Benson thought of strippers as machines. They were mechanical, no question about it. And artificial - when the bra came off, he could see the U-shaped surgical incision beneath each breast, where the plastic had been inserted.

Jaglon would love this, he thought. It would fit right into his theories about machine sex. Jaglon was one of the Development boys and he was preoccupied with the idea of artificial intelligence merging with human intelligence. He argued that, on the one hand, cosmetic surgery and implanted machinery were making man more mechanical, while on the other hand robot developments were making machines more human. It was only a matter of time before people began having sex with humanoid robots.

Perhaps it's already happening, Ellis thought, looking at the stripper. He looked back at the audience, satisfying himself that Benson was not there. Then he checked a phone booth in the back, and the men's room.

The men's room was small and reeked of vomit. He grimaced again, and stared at himself in the cracked mirror over the washbasin. Whatever else was true about the Jackrabbit Club, it produced an olfactory assault. He wondered if that mattered to Benson.

He went back into the club itself and made his way toward the door. "Find him?" the manager asked.

Ellis shook his head and left. Once outside, he breathed the cool night air, and got into his car. The notion of smells intrigued him. It was a problem he had considered before, but never really resolved in his own mind.

His operation on Benson was directed toward a specific part of the brain, the limbic system. It was a very old part of the brain, in terms of evolution. Its original purpose had been the control of smell. In fact, the old term for it was rhinencephalon - the "smelling brain."

The rhinencephalon had developed 150 million years ago, when reptiles ruled the earth. It controlled the most primitive behavior - anger and fear, lust and hunger, attack and withdrawal. Reptiles like crocodiles had little else to direct their behavior. Man, on the other hand, had a cerebral cortex.

But the cerebral cortex was a recent addition. Its modern development had begun only two million years ago; in its present state, the cerebral cortex of man was only 100,000 years old. In terms of evolutionary time scales, that was nothing. The cortex had grown up around the limbic brain, which remained unchanged, embedded deep inside the new cortex. That cortex, which could feel love, and worry about ethical conduct, and write poetry, had to make an uneasy peace with the crocodile brain at its core. Sometimes, as in the case of Benson, the peace broke down, and the crocodile brain took over intermittently.

What was the relationship of smell to all this? Ellis was not sure. Of course, attacks often began with the sensation of strange smells. But was there anything else? Any other effect?

He didn't know, and as he drove he reflected that it didn't much matter. The only problem was to find Benson before his crocodile brain took over. Ellis had seen that happen once, in the NPS. Ellis had watched it through the one-way glass. Benson had been quite normal - and suddenly he had lashed out against the wall, striking it viciously, picking up his chair, smashing it against the wall. The attack had begun without warning, and had been carried out with utter, total, unthinking viciousness.

Six a.m., he thought. There wasn't much time.

"What is it, some kind of emergency?" Farley asked, unlocking the door to Autotronics.

"You could say so," Morris said, standing outside, shivering. It was a cold night, and he had been waiting half an hour. Waiting for Farley to show up.

Farley was a tall, slender man with a slow manner. Or perhaps he was just sleepy. He seemed to take forever to unlock the offices and let Morris inside. He turned on the lights in a rather plain lobby-reception area. Then he went back toward the rear of the building.

The rear of Autotronics was a single cavernous room. Desks were scattered here and there around several pieces of enormous, glittering machinery. Morris frowned slightly.

"I know what you're thinking," Farley said. "You're thinking it's a mess."

"No, I- "

"Well, it is. But we get the job done, I can tell you that." He pointed across the room. "That's Harry's desk, next to Hap."

"Hap?"

Farley gestured to a large, spidery metal construction across the room. "Hap," he said, "is short for Hopelessly Automatic Ping-pong Player." He grinned. "Not really," he said. "But we have our little jokes here."
