"It's like I'm sliding sideways through time and space," Quentin explained.
Vivienne nodded encouragingly.
"You might have seen that movie
Sliding Doors
with Gwyneth Paltrow," he continued. "Maybe, in this continuum, it stars Renee Zellweger."
"I'm sure it was Uma Thurman."
"Whoever." Quentin took another sip from his beer. "Sliding sideways, she was. Only for me, it's happening all the time."
"All the time?" Vivienne asked, raising an eyebrow. "How can that be?"
"It's like Stephen Hawkings explains. You know, that we live in an infinity of parallel universes. Only that while most people stay in one spacetime continuum all their lives, I'm constantly sliding through all of them. I don't go backwards and forwards in time. I just go forwards, but the universe I'm in changes around me. And I've got no control of it any more than most people have any choice about which parallel universe they spend the whole of their lives in."
Quentin paused to assess Vivienne's reaction. Was she humouring him? He often felt the urge to confess his predicament. He knew that the Quentin who would live with the confession was the Quentin whose body he was currently occupying and who would, no doubt, be thoroughly confused by the memory of this occasion.
Vivienne tapped her cigarette on the ashtray. "Go on," she urged him.
"Are you sure?" Quentin asked.
Most women he spoke to on this matter would now ask "What you on?" Or they would pretend not to have heard anything. He was more anxious than he should be. Why should he care what Vivienne thought about the Quentin she had just met? Not all Quentins were especially kind to him for the moment of his residency. He had several times suffered venereal disease, war wounds, and an uncomfortably generous waistline.
"Yes. It's fascinating," said Vivienne, puffing smoke from her cigarette and running a long fingernail along the rim of her wine glass.
"I've seen so many different worlds," Quentin continued. "There are those where the Cold War persisted with the Soviet Union under President Andropov until the present day. There are those where President Kennedy was not assassinated at Houston. There are those where the Sex Pistols never existed. There's even one where some Arab terrorists flew Boeing 747s into the World Trade Center."
Vivienne raised her eyebrows. "I can't believe that! It's like imagining that Sir John Lennon never became the world's best selling novelist."
"I've seen that. He was assassinated, in fact," Quentin admitted. "I've even been in a universe where the richest man in the world was that geek who runs Microsoft."
"I can't believe that either! How could IBM, Sun or Lotus allow that to happen?"
"It's like everything since the time I was born in the early 1960s that could happen has happened. Everything before then is the same in all the universes I've inhabited, but after that it sort of diverges."
"No nuclear wars?"
"Not ones I've survived, though there was a small one in the Middle East in the 1970s that led to universal disarmament. It's amazing what difference a few radioactive craters can make to a world!"
"I can imagine!" Vivienne said.
There was a curious sparkle in her eyes that suggested to Quentin that she was genuinely fascinated. She showed none of the amused scepticism that usually accompanied the most sympathetic ears to his predicament. Was she simply very good at hiding her real thoughts? Or was she playing him along?
"I once decided to write an account of my life," Quentin continued. "I had this 4GHz computer running this operating system called Winix. It was fantastic! And this was a few years back, whereas the best computers hereabouts aren't a quarter as fast. Anyway, I wrote all day and all night, while the wife I had, a pretty woman I've not seen since, kept moaning about me staying up. Then I thought I'd review what I'd written. And you know what?"
"What?" wondered Vivienne, raising her eyebrows in apparent interest.
"I didn't recognise what I read at the start of my account. It was like someone else had written it with totally different memories. It was then it occurred to me that there is a sort of continuum of Quentins, just like me, also sliding sideways through space and time. In fact, maybe everyone has a host of selves like me, perhaps an infinity of them in the infinity of parallel universes. And maybe people like me are everywhere."
"Fascinating!" remarked Vivienne, stubbing out her cigarette.
Quentin scrutinised Vivienne closely. Despite her apparent encouragement, Quentin was still half-expecting a sarcastic rejoinder. Did she really believe him? She was an attractive woman, who carried around with her a self-assurance that would normally manifest itself in contempt towards a man like him, any man, who told a story that must seem ridiculously far-fetched.
"You think I'm mad, don't you?" he asked her, as she brushed her black shoulder length hair off the sharp shoulders of her Giuseppe Marconi suit.
"Not at all," Vivienne said with a smile. "In fact, I think I might be falling in love with you."
