And if she hadn39。t won an ecology essay petition and a prize of places for two aboard Sea Shepherd, neither of them would be here. She rested her hand on Gary39。s shoulder and looked at him cheekily. You may be a pain in the neck sometimes, but I39。m glad you39。re ing with me. As Southampton slid astern, Sea Shepherd nosed into the thumping waters of the English Channel. At that moment the sun squinted through a crack in the cloud. On the horizon the sky39。s grey paint was peeling, revealing blue. A good omen? Gary followed Susan down the panionway. See you at dinner, he said, before entering the cabin he shared with Norman. As one of the girls, Susan had Vanessa for a room mate. Next door were Yves and Darren. Susan hesitated outside her cabin, fiddled with her cardigan, ran a b through her hair. Then, head held high, she made her entrance. Vanessa wasn39。t there. Susan relaxed, smiling at herself. The smile faded fast. She39。s taken the bottom bunk! I was here first. Susan stared, glared at the fancy nightdress laid out on the pillow. Did she have the nerve to move it? No, not quite. Fuming, she started to unpac k. Sweaters, Tshirts, jeans, shorts and a dress. She yanked open the wardrobe door. A row of eye catching outfits hung neatly on hangers. It39。s like a fashion store, Susan muttered, shoving the hangers aside to make space for her own clothes. In the bathroom she opened the mirrorfronted cabi on the wall. It was crammed with bottles and jars. Perfume, shampoo, creams ... Susan slammed the cabi shut and pulled a face in the glass. Meanwhile Gary was trying to make friends with Norman. Hard wor k. Norman proved to be a very serious young man, much given to using long words. Must39。ve swallowed a dictionary, Gary thought. But he kept up the conversation. T hen the studious teenager produced a pac k of cards and proceeded to do a series of conjuring tric ks that made Glly could almost smell his breathmustard gas and roses. It was a wrong number. Billy hung up. There was a soft drink bottle on the windowsill. Its label boasted that it contained no nourishm ent whatsoever. The American fliers turned in their uniforms, became high school kids. And Hitler turned into a baby, Billy Pilgrim supposed. That wasn39。t in the movie. Billy was extrapolating. Everybody turned into a baby, and all humanity, without exception, conspired biologically to produce two perfect people named Adam and Eve, he supposed. Billy saw the war movies bac kwards then forwardsand then it was time to go out into his backyard to meet the flying saucer. Out he went, his blue and ivory feet crushing the wet salad of the lawn. He stopped, took a swig, of the dead champagne. It was like 7Up. He would not raise his eyes to the sky, though he knew there was a flying saucer from Tralfamadore up there. He would see it soon enough, inside and out, and he would see, too, where it came from soon enoughsoon enough. Overhead he heard the cry of what might have been a melodious owl, but it wasn39。t a melodious owl. It was a flying saucer from Tralfamadore, navigating in both space and time, therefore seeming to Billy Pilgrim to have e from nowhere all at once. Somewhere a big dog barked. The saucer was one hundred feet in diameter, with portholes around its rim. The light from the portholes was a pulsing purple . The only noise it made was the owl song. It came down to hover over Billy, and to enclose him in a cylinder of pulsing in purple light. Now there was the sound of a seeming kiss as an airtight hatch in the bottom of the saucer was opened. Down snaked a ladder that was outlined in pretty lights like a Ferris wheel. Billy39。s will was paralyzed by a zap gun aimed at him from one of the portholes. It became imperative that he take hold of the bottom rung of the sinuous ladder, which he did. The rung was electrified, so that Billy39。s hands locked onto it hard. He was hauled into the airloc k, and machinery closed the bottom door. Only then did the ladder, wound onto a reel in the airloc k, let him go. Only then did Billy39。s brain start working again. There were two peepholes inside the airloc kwith yellow eyes pressed to them. There was a speaker on the wall. The Tralfamadorians had no voice box
