that,â said Bigmac, strafing the silent shops with an invisible machine gun.
âBut if he never got born how did they knowheâd existed?â said Yo-less. âDidnât make any sense to me.â
âHow come youâre such an expert?â said Wobbler.
âWell, Iâve got three shelves of Star Trek videos,â said Yo-less.
âAnorak alert!â
âNerd!â
âTrainspotter!â
â Anyway ,â said Yo-less, âif you changed things, maybe youâd end up not going back in time, and there you would be, back in time, I mean, except you never went in the first place, so you wouldnât be able to come back on account of not having gone. Or , even if you could get back, youâd get back to another time, like a sort of parallel dimension, because if the thing you changed hadnât happened then you wouldnâtâve gone, so you could only come back to somewhere you never went. And there youâd be â stuck.â
They tried to work this out.
âHuh, youâd have to be mad even to understand time travel,â said Wobbler eventually.
âJob opportunity for you there, Johnny,â said Bigmac.
â Bigmac ,â said Yo-less, in a warning voice.
âItâs all right,â said Johnny. âThe doctor said I just worry about things too much.â
âWhat kind of loony tests did you have?â said Bigmac. âBig needles and electric shocks and that?â
âNo, Bigmac,â sighed Johnny. âThey donât do that. They just ask you questions.â
âWhat, like âare you a loony?ââ
âItâd be sound to go a long way back in time,â said Wobbler. âBack to the dinosaurs. No chance of killing your grandad then, unless heâs really old. Dinosaursâd be all right.â
âGreat!â said Bigmac. âThen I could wipe âem out with my plasma rifle! Oh, yes!â
âYeah,â said Wobbler, rolling his eyes. âThatâd explain a lot. Why did the dinosaurs die out sixty-five million years ago? Because Bigmac couldnât get there any earlier.â
âBut you havenât got a plasma rifle,â said Johnny.
âIf Wobbler can have a time machine, then I can have a plasma rifle.â
âOh, all right.â
âAnd a rocket launcher.â
A time machine, thought Johnny. That would be something. You could get your life exactly as you wanted it. If something nasty turned up, you could just go back and make sure that it didnât. You could go wherever you wanted and nothing bad would ever have to happen.
Around him, the boysâ conversation, as their conversations did, took on its own peculiar style.
âAnyway, no oneâs proved the dinosaurs did die out.â
âOh, yeah, right, sure, theyâre still around, are they?â
âI mean pâraps they only come out at night, or are camouflaged or something â¦â
âA brick-finished stegosaurus? A bright red Number 9 brontosaurus?â
âHey, neat idea. Theyâd go round pretending to be a bus, right, and people could get on â but they wouldnât get off again. Oooo-Eee-Oooo â¦â
âNah. False noses. False noses and beards. Then just when people arenât expecting it â UNK! Nothing on the pavement but a pair of shoes and a really big bloke in a mac, shuffling away â¦â
Paradise Street, thought Johnny. Paradise Street was on his mind a lot, these days. Especially at night.
I bet if you asked the people there if time travel was a good idea theyâd say yes. I mean, no one knows what happened to the dinosaurs, but we know what happened to Paradise Street.
I wish I could go back to Paradise Street.
Something hissed.
They looked around. There was an alleyway between the charity clothes shop and the video library. The hissing came from there, except now it had changed into a snarl.
It
