C Is for Corpse

lettering on a painted scroll, as though by declaration of the conquistadors.
    I tried the knob, expecting to have to experiment with my key picks. Instead, the door swung open with a low-pitched creak that might have been contrived by a special-effects man. Waning daylight filtered in. The room yawned before me, barren, stripped of everything. No file cabinets, no furniture, no fixtures. A crumpled cigarette pack, some loose boards, and a couple of bent nails were scattered across the floor. This department had literally been dismantled at some point and God only knew where the old records were now. It was possible they were somewhere in one of the abandoned hospital rooms above, but I really didn't want to go up there by myself. I'd promised Jonah I wouldn't be stupid and I was trying to be a good scout on that score. Besides, something else was nagging at me.
    I returned to the stairs, descending. What was that little voice in the back of my head murmuring? It was like a radio playing in the next room. I could pick up only a faint phrase now and then.
    When I reached the basement, I crossed to the radiology office and tried the knob. Locked. I got out my key picks and played around for a while. This was one of those "burglar-proof locks that can be picked, but it really is a pain in the ass. Still, I wanted to see what was in there and I worked patiently. I was using a set of rocker picks, with random depth cuts spaced along the top, the back side of each pick ground to an oval. The whole idea is that with enough different cut combinations, together with an applied rocking motion, somewhere along the way all the pins will, by chance, be raised to the shear line at the same time, popping the lock.
    Like hiding, the only way to approach the whole process is to give oneself up to it. I stood there for maybe twenty minutes, easing the pick forward, rocking it, applying slight pressure when I felt movement of any sort. Lo and behold, the sucker gave way and I let out a little exclamation of delight. "Oh, wow. Hey, that's great." It's this sort of shit that makes my job fun. Also illegal, but who was going to tell?
    I eased into the office. I flipped the overhead light on. It looked like ordinary office space. Typewriters and telephones and file cabinets, plants on the desks, pictures on the walls. There was a small reception area where I imagined patients seated, waiting to be called for their X rays. I wandered through some of the rooms in the rear, picturing the procedures for chest X rays and mammograms, upper G.I. series. I stood in front of the machines and opened one of the manuals I'd brought in from the car.
    I checked the diagrams against the various dials and gauges on the X-ray equipment itself. It was a match, more or less. Maybe some variation according to year, make, or model of the actual machinery installed. Some of it looked like the stuff of science fiction. Massive nose cone on a swinging arm. I stood there, manual open in my arms, pages pressed to my chest while I stared at the table and the lead apron that looked like a baby bib for a giant. I thought about the X rays I'd had taken of my left arm two months ago, just after I'd been shot.
    It wasn't as if the idea came to me all at once. It formed around me, like fairy dust, gradually taking shape. Bobby had been out here all by himself, just like this. Night after night, searching for the handgun that had Nola's fingerprints on it. He knew who had hidden it, so he must have formed some kind of theory about the hiding place. I had to guess that he'd found the gun and that's why he was killed. Maybe he'd actually retrieved it, but I didn't think so. I'd been operating on the assumption that it was still hidden out here and that still seemed like a good bet. He'd made some little notes to himself, doodling the I.D. number of a corpse in his little red book and again in the pages of a radiology manual he'd acquired.
    The phrases running through my head began to connect. Maybe you should X-ray the corpse, said I to myself Maybe that's what Bobby did and maybe that's why he made the penciled notation in the radiology book. Maybe the gun is inside the corpse. I thought about it briefly, but I couldn't see why I shouldn't give it a try. The worst that could happen (aside from my getting caught) was that I'd be wasting time and making a colossal fool of myself This would not be a first.
    I left my handbag and the manuals on one of the X-ray tables and went
