For Miriam and me, it was the first in a chain of events that were to change our lives mine especially in a way that neither of us could possibly have imagined. For what we stumbled across that night was not the beginning of the story. If I am to believe what I have learned so far, the beginning was before and beyond Time as we know it. O ur lifestreams along with those of the handful of other people who became involved have established a brief interface with a cosmic event whose magnitude dwarfs the imagination. If this is starting to sound heavy, hold on. I39。m not ki dding. This is going to change all our lives before it39。s over. Or end them. It39。s that big and that simple. Even so, I don39。t guarantee to explain everything. You39。ll have to figure some of this out for yourselves. That39。s the39。 way it works. But it39。s one hell of a story. I39。ve got notes, photographs, taperecordings. All the evidence is loc ked in a safety deposit box registered in my name at the Forty seventh and Madison Branch of the Chase Manhattan Bank. I39。ve put down everything I saw and everything that was said just the way it happened. It can all be checked against this account I am writing now. It39。s all true. Every word of it. So help me God. Before we go any further, I39。d better tell you who I am. My name is Leo Resnic k. I39。m thirty five years old and, at the time this thing started, I was a partner in the Manhattan law firm of Gutzman, Schonfeld and Resnick. The firm specialises in corporate legal work but occasionally handles divorce suits for its more favoured clients. I was supposed to be making good as a claims attorney. How true that 9 is, is not for me to say, but they put my name on the door last Christmas so I guess I must have been doing something 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 replacing 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 f or 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 preferred 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 gues
