      Wide shot.

      New Richmond, Virginia. Not the old Richmond, the historic capital of historical old Virginia, that sprawl of creaking tedium, but the New. The old Richmond was destroyed over a century ago, razed to the ground during riots which lasted two months. After decades of putting up with dreadful shopping facilities, a bewilderingly dull Old Town and no good restaurants to speak of, the residents suddenly went non-linear and strode across the city like avenging angels, destroying everything in their wake. It was great.

      Spin doctors blamed downtown decay, crack wars, the cast of the moon. Personally, I think everyone just got really bored, and either way good riddance to it. The old Richmond was a content-free mess, a waste of a good, level patch within sight of the pleasingly pointy Blue Ridge Mountains. Everyone agreed it was much better off as a landing strip, a refuelling point for the MegaMalls.

      The MegaMalls are aircraft – five miles square, two hundred storeys high – which majestically transport passengers from one side of the continent to the other, from the bottom to the top; from wherever they've been to wherever they seem to think will be better. The biggest oblongs of all time, a fetching shade of consumer goods black, studded with millions of points of light and so big they transcend function and become simply a shape again.

      When oblongs grow up, they all want to be MegaMalls.

      Inside are thousands of stores, twenty-storey atriums, food courts the size of small towns, dozens of multiplex cinemas and a range of hotels to suit every wallet which has a Gold Card in it. All this and more arranged round wide, sweeping avenues, a thousand comfortable nooks and crannies, and so many potted plants they count as an ecosystem in their own right. Safe from the rest of the world, cocooned 20,000 feet up in the air.

      Heaven on earth, or cruising just above it: all of the good, clean, buyable things in life crammed into a multi-storey funhouse.

      Eighty-three years ago, MegaMall Flight MA 156 stopped for routine refuelling on the site of old Richmond, and never took off again. It was merely a bureaucratic problem at first – the kind that the massed brains of all time could never have got to the bottom of, but which some poorly paid clerk could have solved instantly. If he'd had a mind to. If he hadn't been on his break.

      After a few hours, the richer patrons started leaving by the roads. They didn't have time for this shit. They had to be somewhere else. Everybody else just complained a little, ordered another meal or bought some more shoes, and settled down to wait.

      Then, after a few more hours, it transpired there was a minor problem with the engines. This was a little more serious. When you've got a problem with a car, you open the hood and there it is. You can point at the errant part. When the engine's the size of the Empire State Building on steroids, you know you've got a long night ahead. It takes fourteen people just to hold the manual. The engineers sent repair droids scurrying off into the deep recesses, but eventually they came back, electronically shaking their heads and whistling through their mechanical teeth. It was only a minor problem, they were sure, but they
