Somewhere above me, a door slammed and I jumped. I heard someone coping down the stairs, whistling aimlessly. A security guard? Someone coming back after work? I absolutely could not move. It was too late for action, too late for escape, and there was no place to hide. Transfixed, I stared at the door as footsteps approached. Someone paused in the corridor, singing the first few snatches of "Someone to Watch over Me." The knob turned and Dr. Fraker came in, glancing up, startled, at the sight of me.

"Oh! Hello. I didn't expect to see you here," he said. "I thought you were off talking to Kelly."

I let out a breath and found my voice. "I did that. A little while ago."

"Jesus, what's wrong? You're as white as a ghost."

I shook my head. "I was just on my way out when I heard the door slam. You scared the shit out of me." My voice cracked in the middle of the sentence as if I'd just reached puberty.

"Sorry. I didn't mean to spook you like that." He had on his surgical greens. I watched him cross the counter and open a drawer, taking out instruments. From the next drawer down, he took out a vial and a syringe.

"Listen, we've got a problem," I said.

"Oh really. What's that?" Dr. Fraker turned to smile at me and Nola's line popped into my head. "We're talking about a lunatic. Someone so crazy," she had whispered. Dr. Fraker's eyes were fixed on mine as he filled the syringe. The penny dropped. She hadn't wanted to stay in the marriage. She had wanted out. Bobby Callahan in his naivete had thought he could help.

It was there in his face and the lazy way he moved. This man meant to kill me. Judging from the tools he'd assembled, he had all of the equipment he needed-nice table with a drain, hacksaws, scalpels, a working disposal just under the sink. He knew anatomy too, all the tendons and ligaments. I pictured a turkey wing, how you have to bend it backward to ease the blade into that joint.

I usually cry when I'm scared and I could feel tears well up. Not sorrow, but horror. Given all the lies I'd told in my life, right then I couldn't think of one. My mind was empty of thought. There I stood with the X ray in my hand, the truth, I'm sure, written all over my face. My only hope was to act before he did and move twice as fast.

I dove for the door, fumbling with the knob. I yanked it open and ran for the stairs, taking two at a time, then three, looking back with a moan of raw fear. He was coming out of the door, syringe held loosely in one hand. What scared me was that he was moving slowly, as if he had all the time in the world. He'd taken up the song lyric where he left off, a sort of tuneless rendition that didn't do the Gershwins justice.

"Like a little lamb who's lost in the wood… 1 know I could always be good… to one who'll watch over me…"

I reached the top of the stairs. What did he know that I didn't know? Why did he feel that this leisurely pace would suit when I was flying toward the entrance? I lowered a shoulder and slammed up against the double doors, but neither gave way. I rammed them again. The entranceway, locked like this, formed a small cul-de-sac. If I gave him time to reach the corridor, I'd have no way out. I reached the hall just as he got to the top of the stairs.

Chit, chit. I could hear his footsteps scratch on the tile while he sang on.

"Although he may not be the man some girls think of as handsome, to my heart he'll carry the key…"

Still taking his time. I wanted to scream, but what was the point? The building was empty. It was locked up tight. Dark except for the pale light filtering in from the parking lot. I needed a weapon. Dr. Fraker had his little syringe filled with whatever he meant to pop me with. He was a big guy too, and once he made contact, I was in trouble.

I flew down the hall to the old medical-records room and slammed the door back on its hinge. I snatched up a two-by-four, still running, and headed back out into the corridor, racing for the far end. There had to be stairs. There had to be windows to smash, some way out.

Behind me, from a man who couldn't even carry a tune, I heard… "Won't you tell him please to put on some speed, follow my lead, oh how I need, someone to watch over me…"

I reached the stairwell and headed up, beginning to analyze the situation as I ran. At this rate, he could chase me all over the building. I'd soon be exhausted and he wouldn't even be breaking a sweat. Not a good idea, this form of pursuit. I reached the landing and snatched for the door. Locked. There was just one more floor. Was I being trapped or herded? In either case, I had the feeling he was in charge, that he'd set this all up in advance.
