Scenarios

'Not specifically, no. It could be anybody with a working knowledge of zoology and the right-or wrong- contracts for disposal of the specimens.'

'Someone connected with Fleishhacker, maybe?'

'That's possible. But I damned well hope not.'

'So your best guess is what?'

'A professional at this sort of thing,' Factor said. 'They don't usually rob large zoos like ours-there's too much risk and too much publicity; mostly they hit small zoos or private collectors, and do some poaching on the side. But it has been known to happen when they hook up with buyers who are willing to pay premium prices.'

'What makes you think it's a pro in this case? Why not an amateur? Or even kids out on some kind of crazy lark?'

'Well, for one thing, the thief seemed to know exactly what he was after each time. Only expensive and endangered specimens were taken. For another thing, the locks on the building and cage doors were picked by an expert-and that's not my theory, it's the police's.'

'You figure he'll try it again?'

'Well, he's four-for-four so far, with no hassle except for the minor scare Sam Dettlinger gave him; that has to make him feel pretty secure. And there are dozens more valuable, prohibited specimens in the gardens. I like the odds that he'll push his luck and go for five straight.'

But so far the thief hadn't pushed his luck. This was the third night I'd been on the job and nothing had happened. Nothing had happened during my daylight investigation either; I had put out feelers all over the city, but nobody admitted to knowing anything about the zoo thefts. Nor had I been able to find out anything from any of the Fleishhacker employees I'd talked to. All the information I had on the case, in fact, had been furnished by Lawrence Factor in my office three days ago.

If the thief was going to make another hit, I wished he would do it pretty soon and get it over with. Prowling around here in the dark and the fog and that damned icy wind, waiting for something to happen, was starting to get on my nerves. Even if I was being well paid, there were better ways to spend long, cold winter nights. Like curled up in bed with a copy of Black Mask or Detective Tales or one of the other pulps in my collection. Like curled up in bed with my lady love, Kerry Wade…

I moved ahead to the near doors of the aviary and tried them to make sure they were still locked. They were. But I shone my flash on them anyway, just to be certain that they hadn't been tampered with since the last time one of us had been by. No problem there, either.

There were four of us on the grounds-Dettlinger, Hammond, Kirby, and me-and the way we'd been working it was to spread out to four corners and then start moving counterclockwise in a set but irregular pattern; that way, we could cover the grounds thoroughly without all of us congregating in one area, and without more than fifteen minutes or so going by from one building check to another. We each had a walkie-talkie clipped to our belts so one could summon the others if anything went down. We also used the things to radio our positions periodically, so we'd be sure to stay spread out from each other.

I went around on the other side of the aviary, to the entrance that faced the long, shallow pond where the bigger tropical birds had their sanctuary. The doors there were also secure. The wind gusted in over the pond as I was checking the doors, like a williwaw off the frozen Arctic tundra; it made the cypress trees genuflect, shredded the fog for an instant so that I could see all the way across to the construction site of the new Primate Discovery Center, and clacked my teeth together with a sound like rattling bones. I flexed the cramped fingers of my left hand, the one that had suffered some nerve damage in a shooting scrape a few months back; extreme cold aggravated the chronic stiffness. I thought longingly of the hot coffee in my thermos. But the thermos was over at the zoo office behind the carousel, along with my brown-bag supper, and I was not due for a break until one o'clock.

The path that led to Monkey Island was on my left; I took it, hunching forward against the wind. Ahead, I could make out the high dark mass of man-made rocks that comprised the island home of sixty or seventy spider monkeys. But the mist was closing in again, like wind-driven skeins of shiny gray cloth being woven together magically; the building that housed the elephants and pachyderms, only a short distance away, was invisible.

One of the male peacocks that roam the grounds let loose with its weird cry somewhere behind me. The damned things were always doing that, showing off even in the middle of the night. I had never cared for peacocks much, and I liked them even less now. I wondered how one of them would taste roasted with garlic and anchovies. The thought warmed me a little as I moved along the path between the hippo pen and the brown bear grottos, turned onto the wide concourse that led past the front of the Lion House.

In the middle of the concourse was an extended oblong pond, with a little center island overgrown with yucca trees and pampas grass. The vegetation had an eerie look in the fog, like fantastic creatures waving their appendages in a low-budget science fiction film. I veered away from them, over toward the glass-and-wire cages that had been built onto the Lion House's stucco facade. The cages were for show: inside was the Zoological Society's current pride and joy, a year-old white tiger named Prince Charles, one of only fifty known white tigers in the world. Young Charley was the zoo's rarest and most valuable possession, but the thief hadn't attempted to steal him. Nobody in his right mind would try to make off with a frisky, five-hundred-pound tiger in the middle of the night.

Charley was asleep; so was his sister, a normally marked Bengal tiger named Whiskers. I looked at them for a few seconds, decided I wouldn't like to have to pay their food bill, and started to turn away.

Somebody was hurrying toward me, from over where the otter pool was located.

I could barely see him in the mist; he was just a moving black shape. I tensed a little, taking the flashlight out of my pocket, putting my cramped left hand on the walkie-talkie so I could use the thing if it looked like trouble. But it wasn't trouble. The figure called my name in a familiar voice, and when I put my flash on for a couple of seconds I saw that it was Sam Dettlinger.

'What's up?' I said when he got to me. 'You're supposed to be over by the gorillas about now.'

'Yeah,' he said, 'but I thought I saw something about fifteen minutes ago, out back by the cat grottos.'

'Saw what?'

'Somebody moving around in the bushes,' he said. He tipped back his uniform cap, ran a gloved hand over his face to wipe away the thin film of moisture the fog had put there. He was in his forties, heavyset, owl-eyed, with carrot-colored hair and a mustache that looked like a dead caterpillar draped across his upper lip.

'Why didn't you put out a call?'

'I couldn't be sure I actually saw somebody and I didn't want to sound a false alarm; this damn fog distorts everything, makes you see things that aren't there. Wasn't anybody in the bushes when I went to check. It might have been a squirrel or something. Or just the fog. But I figured I'd better search the area to make sure.'

'Anything?'

'No. Zip.'

'Well, I'll make another check just in case.'

'You want me to come with you?'

'No need. It's about time for your break, isn't it?'

He shot the sleeve of his coat and peered at his watch. 'You're right, it's almost midnight-'

And something exploded inside the Lion House-a flat, cracking noise that sounded like a gunshot.

Both Dettlinger and I jumped. He said, 'What the hell was that?'

'I don't know. Come on!'

We ran the twenty yards or so to the front entrance. The noise had awakened Prince Charles and his sister; they were up and starting to prowl their cage as we rushed past. I caught hold of the door handle and tugged on it, but the lock was secure.

I snapped at Dettlinger, 'Have you got a key?'

'Yeah, to all the buildings…'

He fumbled his key ring out, and I switched on my flash to help him find the right key. From inside, there was cold, dead silence; I couldn't hear anything anywhere else in the vicinity either, except for faint animal sounds lost in the mist. Dettlinger got the door unlocked, dragged it open. I crowded in ahead of him, across a short foyer and through another door that wasn't locked, into the building's cavernous main room.

A couple of the ceiling lights were on; we hadn't been able to tell from outside because the Lion House had no windows. The interior was a long rectangle with a terra cotta tile floor, now-empty feeding cages along the entire facing wall and the near side wall, another set of entrance doors in the far side wall, and a kind of indoor
