He pointed over at the rear side wall. "That door next to the last cage."
"Any other way in or out of those rooms?"
"No. Except through the grottos, but the cats are out there." I went around to the interior door he'd indicated. Like all the others, it was locked. I said to Dettlinger, "You do have a key to this door?"
He nodded, got it out, and unlocked the door. I told him to keep watch out here, switched on my flashlight, and went on through. The flash beam showed me where the light switches were; I flicked them on and began a quick, cautious search. The door to one of the meat lockers was open, but nobody was hiding inside. Or anywhere else back there.
When I came out I shook my head in answer to Dettlinger's silent question. Then I asked him, "Where's the nearest phone?"
"Out past the grottos, by the popcorn stand."
"Hustle out there and call the police. And while you're at it, radio Hammond to get over here on the double-"
"No need for that," a new voice said from the main entrance. "I'm already here."
I glanced in that direction and saw Gene Hammond, the other regular night watchman. You couldn't miss him; he was six-five, weighed in at a good two-fifty, and had a face like the back end of a bus. Disbelief was written on it now as he stared across at Kirby's body.
"Go," I told Dettlinger. "I'll watch things here."
"Right."
He hurried out past Hammond, who was on his way toward where I stood in front of the cage. Hammond said as he came up, "God-what happened?"
"We don't know yet."
"How'd Kirby get in there?"
"We don't know that either." I told him what we did know, which was not much. "When did you last see Kirby?"
"Not since the shift started at nine."
"Any idea why he'd have come in here?"
"No. Unless he heard something and came in to investigate. But he shouldn't have been in this area, should he?"
"Not for another half-hour, no."
"Christ, you don't think that he-"
"What?"
"Killed himself," Hammond said.
"It's possible. Was he despondent for any reason?"
"Not that I know about. But it sure looks like suicide. I mean, he's got that gun in his hand, he's all alone in the building, all the doors were locked. What else could it be?"
"Murder," I said.
"How? Where's the person who killed him, then?"
"Got out through one of the grottos, maybe."
"No way," Hammond said. "Those cats would maul anybody who went out among 'em-and I mean anybody; not even any of the handlers would try a stunt like that. Besides, even if somebody made it down into the moat, how would he scale that twenty-foot back wall to get out of it?"
I didn't say anything.
Hammond said, "And another thing: why would Kirby be locked in this cage if it was murder?"
"Why would he lock himself in to commit suicide?"
He made a bewildered gesture with one of his big hands.
"Crazy," he said. "The whole thing's crazy."
He was right. None of it seemed to make any sense at all.
I knew one of the homicide inspectors who responded to Dettlinger's call. His name was Branislaus and he was a pretty decent guy, so the preliminary questions-and-answers went fast and hassle-free. After which he packed Dettlinger and Hammond and me off to the zoo office while he and the lab crew went to work inside the Lion House.
I poured some hot coffee from my thermos, to help me thaw out a little, and then used one of the phones to get Lawrence Factor out of bed. He was paying my fee and I figured he had a right to know what had happened as soon as possible. He made shocked noises when I told him, asked a couple of pertinent questions, said he'd get out to Fleishhacker right away, and rang off.
An hour crept away. Dettlinger sat at one of the desks with a pad of paper and a pencil and challenged himself in a string of tic-tac-toe games. Hammond chain-smoked cigarettes until the air in there was blue with smoke. I paced around for the most part, now and then stepping out into the chill night to get some fresh air: all that cigarette smoke was playing merry hell with my lungs. None of us had much to say. We were all waiting to see what Branislaus and the rest of the cops turned up.
Factor arrived at one-thirty, looking harried and upset. It was the first time I had ever seen him without a tie and with his usually immaculate Robert Redford hairdo in some disarray. A patrolman accompanied him into the office, and judging from the way Factor glared at him, he had had some difficulty getting past the front gate. When the patrolman left I gave Factor a detailed account of what had taken place as far as I knew it, with embellishments from Dettlinger. I was just finishing when Branislaus came in.
Branny spent a couple of minutes discussing matters with Factor. Then he said he wanted to talk to the rest of us one at a time, picked me to go first, and herded me into another room.
The first thing he said was, "This is the screwiest shooting case I've come up against in twenty years on the force. What in bloody hell is going on here?"
"I was hoping maybe you could tell me."
"Well, I can't-yet. So far it looks like a suicide, but if that's it, it's a candidate for Ripley. Whoever heard of anybody blowing himself away in a lion cage at the zoo?"
"Any indication he locked himself in there?"
"We found a key next to his body that fits the little access door in front."
"Just one loose key?"
"That's right."
"So it could have been dropped in there by somebody else after Kirby was dead and after the door was locked. Or thrown in through the bars from outside."
"Granted."
"And suicides don't usually shoot themselves in the chest," I said.
"Also granted, although it's been known to happen."
"What kind of weapon was he shot with? I couldn't see it too well from outside the cage, the way he was laying."
"Thirty-two Iver Johnson."
"Too soon to tell yet if it was his, I guess."
"Uh-huh. Did he come on the job armed?"
"Not that I know about. The rest of us weren't, or weren't supposed to be."
"Well, we'll know more when R and I finishes running a check on the serial number," Branislaus said. "It was intact, so the thirtytwo doesn't figure to be a Saturday Night Special."
"Was there anything in Kirby's pockets?"
"The usual stuff. And no sign of a suicide note. But you don't think it was suicide anyway, right?"
"No, I don't."
"Why not?"
"No specific reason. It's just that a suicide under those circumstances rings false. And so does a suicide on the heels of the thefts the zoo's been having lately."
"So you figure there's a connection between Kirby's death and the thefts?"
"Don't you?"
"The thought crossed my mind," Branislaus said dryly. "Could be the thief slipped back onto the grounds tonight, something happened before he had a chance to steal something, and he did for Kirby-I'll admit the possibility. But what were the two of them doing in the Lion House? Doesn't add up that Kirby caught the guy in there. Why would the thief enter it in the first place? Not because he was trying to steal a lion or a tiger, that's for sure."
"Maybe Kirby stumbled on him somewhere else, somewhere nearby. Maybe there was a struggle; the thief got the drop on Kirby, then forced him to let both of them into the Lion House with his key."
"Why?"
"To get rid of him where it was private."
"I don't buy it," Branny said. "Why wouldn't he just knock Kirby over the head and run for it?"
"Well, it could be he's somebody Kirby knew."
"Okay. But the Lion House angle is still too much trouble for him to go through. It would've been much easier to shove the gun into Kirby's belly and shoot him on the spot. Kirby's clothing would have muffled the sound of the shot; it wouldn't have been audible more than fifty feet away."
