【正文】 y, but they put my name on the door last Christmas so I guess I must have been doing some thing right. Let39。s just say that it brought in enough to eat out in restaurants where they don39。t put the prices on the menus, run a threelitre Porsche Carrera, pay the bills on a nice apartment up on 75th Street and a wee kend place overlooking the Hudson. E xcept that to see the river, you have to stand on the roof. Actually, the house at Sleepy Hollow was left to me by my uncle. Still, it added to my worth and gave me problems like re placing shingles, cutting grass, buying heating oil and alarm systems. And so on. But there were a few bonuses too. Ifyou had time to look, you got to see the leaves change colour, clouds moving across a Panavision piece of sky, hear the wind in the trees, and split kindling for the log fire in the livingroom. The whole BacktoNature bit. To be honest, I didn39。t get up there all that often. I don39。t know about you, but I always got a little tw itchy sitting around just listening to the grass grow. I needed the buzz from the streets, the bigcity hype to get my nerveends tingling. Some of that tangy, rushhour traffic air in my lungs. It sharpens a guy up. Makes him feel human. In town, most of my time was spent wor king. Either at the office or my apartment. Boning up on case law, laying the groundwor k for suits. Looking for angles. I39。m not married. I39。d been going steady with this lady doctor for a couple of years. I guess you could say we were close but neither of us had let it get too serious. In other words, I39。m open to offers. Miriam that39。s the lady doctor knew they came my way now and then. She wasn39。t too wild about it but we always managed to avoid any heavy scenes. So much for romance. I39。ve got a sister, Bella, who39。s married to a dentist up in Boston. She used to play cello with the Philharmonic but now she39。s into kids and clambakes. My parents live in Florida. T hey were always writing to tell me I should visit them more often and that I should holiday in I)isney World. I didn39。t like to tell them that I preferre d Fritz the Cat to Mic key Mouse and that I hadn39。t been to synagogue since Bella39。s wedding. End of life story. There39。s more, of course, but we don39。t need to get into that here. Let39。s get back to where I got involved in this thing. The Manhattan ~ieneral. I had arranged to pick up Miriam between nine fifteen and ninethirty. the plan was to have dinner and catch a late movie by that German guy Fassbinder. I find him a little heavy but Miriam is pletely hooked on the art movie scene. It had been raining hard and I39。d had some trouble in getting a cab. As a result, I didn39。t arrive at the Manhattan General until ninefiftyish. She wasn39。t waiting at the desk. The duty nurse, w ho knew who I was, phoned around and located Miriam in the mue. I tried to figure out what she was doing there. Normally, she works in Emergency and I know she hates losing out. Miriam told the nurse that she39。d be right up. I ducked out to look for a cab, but there was nothing in sight. As I walked bac k into the building, Mir iam stepped out of the elevator. I always liked seeing her in her white coat w ith a stethoscope round her neck. I guess it was because it made me feel like a responsible citizen and because I knew that my parents. would approve if they39。d known about her. Which they didn39。t. Or that w hen she got that white coat and the rest of her things off, she was a really great piece of ass. We gave each other a hellotype kiss, then she took my arm and walked me away from the desk. 39。We may be stuck here for a little while. Did you make a re servation?39。 39。No,39。 I said. 39。I wasn39。t planning on going anywhere fancy. Have you got some kind ofcrisis or are we just going to sneak off and get stiff on lab alcohol?39。 39。Neither,39。 replied Miriam. 39。Listen, an ambulance on an NYPD call brought in a man about half an hour ago. It turned out that he was a DOA who should have gone to the city mue but 39。 she shrugged.39。 maybe they thought we could give him the kiss of life. Anyway, there was something about him that really threw me. I want you to take a look and tell me what you think.39。 She hit the elevator button. I grimaced. 39。You mean in the mue?39。 39。Yes.39。 She smiled. 39。Hey, that39。s something I39。ve never asked you. Have you seen dead bodies before?39。 39。I39。ve seei~ a couple of car crashes,39。 I said. 39。But they were mainly blood and feet sticking out from the blankets.39。 The elevator came. Miriam ushered me in. 39。I)on39。t worry. He39。s still in one piece.39。 I eyed her warily. 39。You promise? No messy exit wounds?39。 39。No. Nothing like that.39。 She took hold ofmy hand and lead me out oft he elevator when it reached the basement. Ihis way, l)r Resnick. I39。ll get you a white coat.39。 Smart move. Putting me in a white coat meant that I couldn39。t pass II out without looking foolish. I posed myself as we entered the mue and walked over to where the body lay halfcovered by a sheet on an autopsy table. What they call the slab. Miriam introduced me to the doctor who was carrying out the postmortem examination on the body. A guy called Wallis. A grey haired chainsmoker who looked as though he39。d seen it all. T here was also a young intern with Harpo Marx hair hovering in the bac kground. His name was Lazzarotti. He gave me the story so far. Two cops in a squad car had spotted the body in an alleyway over on the East Side. It had been stripped naked. There were no clues as to the possible identity of the victim. Nobody in the immediate vicinity had seen or heard anything. The usual story. The cops had radioed for an ambulance, the crew of which claimed to discern lingering signs of life in the body. As a result, they had burned red lights all the way across town to the Manhattan General and had ta ken off again b
