"Yeah," he said after a while, still attacking the oncoming craft, "and a lot of them seem to be politicians and presidents and things."

"What?" I said, wondering what he was talking about.

"The madder people. A lot of them seem to be leaders of countries or religions or armies. The real loonies."

"Aye, I suppose." I said thoughtfully, watching the battle on the screen upside down. "Or maybe they're the only sane ones. After all, they're the ones with all the power and riches. They're the ones who get everybody else to do what they want them to do, like die for them and work for them and get them into power and protect them and pay taxes and buy them toys, and they're the ones who'll survive another big war, in their bunkers and tunnels. So, given things being the way they are, who's to say they're the loonies because they don't do things the way Joe Punter thinks they ought to be done? If they thought the same way as Joe Punter, they'd be Joe Punter, and somebody else would be having all the fun."

"Survival of the fittest."

"Yeah."

"Survival of the — " Jamie drew his breath in sharply and pulled the stick so hard he almost fell off his stool, but he managed to dodge the darting yellow bolts that had driven him into the corner of the screen "- nastiest." He looked up at me and grinned quickly before hunching over the controls again. I drank, nodded.

"If you like. If the nastiest survive, then that's our tough shit."

"'Us' being all us Joe Punters," Jamie said.

"Aye, or everybody. The whole species. If we're really so bad and so thick that we'd actually use all those wonderful H-bombs and Neutron bombs on each other, then maybe it's just as well we do wipe ourselves out before we can get into space and start doing horrible things to other races."

"You mean we'll be the Space Invaders?"

"Yeah!" I laughed, and rocked back on my stool. "That's it! That's really us!" I laughed again and tapped the screen above a formation of red and green flapping things, just as one of them, peeling off to the side of the main pack, dived down firing at Jamie's craft, missing it with its shots but clipping him with one green wing as it disappeared off the bottom of the screen, so that Jamie's craft detonated in a blaze of flashing red and yellow.

"Shit," he said, sitting back. He shook his head.

I sat forward and waited for my craft to appear.

Just a little drunk on my three pints, I cycled back to the island whistling. I always enjoyed my lunch-time chats with Jamie. We sometimes talk when we meet on Saturday nights, but we can't hear when the bands are on, and afterwards I'm either too drunk to talk or, if I can speak, I'm too drunk to recall much of what I've said. Which, come to think of it, is probably just as well, judging by the way people who are normally quite sensible dissolve into gibbering, rude, opinionated and bombastic idiots once the alcohol molecules in their bloodstream outnumber their neurons, or whatever. Luckily, one only notices this if one stays sober oneself, so the solution is as pleasant (at the time, at least) as it is obvious.

My father was asleep in a deckchair in the front garden when I got back. I left the bike in the shed and watched him from the shed door for a while, poised so that if he happened to wake up it would look as though I was just in the act of shutting the door. His head was tilted a little to me and his mouth was slightly open. He had dark glasses on, but I could just see through them to his closed eyes.

I had to go for a piss, so I didn't watch him for very long. Not that I had any particular reason for watching him; I just liked doing it. It made me feel good to know that I could see him and he couldn't see me, and that I was aware and fully conscious and he wasn't.

I went into the house.

I had spent Monday, after a cursory check of the Poles, making one or two repairs and improvements to the Factory, working through the afternoon until my eyes got sore and my father had to call up to me to come down for my dinner.

In the evening it rained, so I had stayed in and watched television. I went to bed early. Eric didn't call.

After I'd got rid of about half the beer I'd drunk in the Arms, I went to have another look at the Factory. I clambered up into the loft, all sunlight and warmth and smelling of old and interesting books, and I decided to clear the place up a bit.

I sorted out old toys into boxes, got a few rolls of carpet and wallpaper back into their places from where they'd fallen, pinned a couple of maps back on to the sloping wooden under-roof, cleared away some of the tools and bits and pieces that I'd used to repair the Factory, and loaded the various sections of the Factory that needed to be loaded.

I found some interesting things while I was doing all this: a home-made astrolabe I'd carved, a box containing the folded-flat parts for a scale model of the defences around Byzantium, the remains of my collection of telegraph-pole insulators, and some old jotters from when my father was teaching me French. Leafing through them, I couldn't see any obvious lies; he hadn't taught me to say anything obscene instead of "Excuse me" or "Can you direct me to the railway station, please? , though I'd have thought the temptation would have been all but irresistible.

I completed tidying the loft, sneezing a few times as the golden space filled with motes of shining dust. I looked over the refurbished Factory again, just because I love looking at it and tinkering with it and touching it and tipping some of its little levers and doors and devices. Finally I dragged myself away, telling myself that I'd get a chance to use it properly soon enough. I would capture a fresh wasp that afternoon to use the following morning. I wanted another interrogation of the Factory before Eric arrived; I wanted more of an idea what was going to happen.

It was a little risky, of course, asking it the same question twice, but I thought the exceptional circumstances demanded it, and it was my Factory, after all.

I got the wasp without any difficulty. It more or less walked into the ceremonial jam-jar which I have always used to hold subjects for the Factory. I kept the jar, sealed with the lid with the holes in it and stocked with a few leaves and a morsel of orange peel, standing in the shade of the river bank while I made a dam there that afternoon.

I worked and sweated in the sunlight of late afternoon and early evening while my father did a bit of painting at the back of the house and the wasp felt its way around the inside of the jar, antennae waving.

Halfway through building the dam — not the best time — I thought it might be amusing to make it an Exploder, so I set the overflow going and trotted up the path to the shed for the War Bag. I brought it back and sorted out the smallest bomb I could find wired for electrical detonation. I attached it to the wires from the torch-firer by the bared ends poking out of the drilled hole in the black metal casing and wrapped the bomb in a couple of plastic bags. I shoved the bomb backwards into the base of the main dam, leading the wires away and back behind the dam, past the static waters backed up behind it to near where the wasp crawled in its jar. I covered the wires over so that it looked more natural, then went on building the dam.

The dam system ended up very big and complicated and included not one but two little villages, one between two of the dams and one downstream from the last one. I had bridges with little roads, a small castle with four towers, and two road tunnels. Just before tea-time I played out the last of the wire from the torch body and took the wasp jar up on to the top of the nearby dune.

I could see my father, still painting the window surrounds of the lounge. I can just remember the designs he used to have on the front of the house, the face turned towards the sea; they were fading even then, but they were minor classics of tripped-out art, as I recall; great sweeping sworls and mandalas that leaped about the house front like Technicolor tattoos, curving round windows and arching over the door. A relic from the days when my father was a hippy, they are worn and gone now, erased by wind and sea and rain and sunlight. Only the vaguest outlines are still discernible now, along with a few freak patches of real colour, like peeling skin.
