Noon is the worst, with its glare and humidity. At about eleven o’clock Snowman retreats back into the forest, out of sight of the sea altogether, because the evil rays bounce off the water and get at him even if he’s protected from the sky, and then he reddens and blisters. What he could really use is a tube of heavy-duty sunblock, supposing he could ever find one.

In the first week, when he’d had more energy, he’d made himself a lean-to, using fallen branches and a roll of duct tape and a plastic tarp he’d found in the trunk of a smashed-up car. At that time he’d had a knife, but he lost it a week later, or was it two weeks? He must keep better track of such things as weeks. The knife was one of those pocket items with two blades, an awl, a tiny saw, a nail file, and a corkscrew. Also a little pair of scissors, which he’d used to cut his toenails and the duct tape as well. He regrets the loss of the scissors.

He was given a knife like that for his ninth birthday, by his father. His father was always giving him tools, trying to make him more practical. In his father’s opinion Jimmy couldn’t screw in a light bulb. So who wants to screw in a light bulb? says the voice in Snowman’s head, a stand-up comic this time. I’d rather do it in bed.

“Shut up,” says Snowman.

“Did you give him a dollar?” Oryx had asked him when he told her about the knife.

“No. Why?”

“You need to give money when someone gives you a knife. So the bad luck won’t cut you. I wouldn’t like it for you to be cut by the bad luck, Jimmy.”

“Who told you that?”

“Oh, someone,” said Oryx. Someone played a big part in her life.

“Someone who?” Jimmy hated him, this someone—faceless, eyeless, mocking, all hands and dick, now singular, now double, now a multitude—but Oryx had her mouth right next to his ear and was whispering, Oh, oh, some, one, and laughing at the same time, so how could he concentrate on his stupid old hate?

In the short period of the lean-to he’d slept on a fold-up cot he’d dragged from a bungalow half a mile away, a metal frame with a foam mattress on top of a grillwork of springs. The first night he’d been attacked by ants, and so he’d filled four tin cans with water and stuck the cot legs into them. That put a stop to the ants. But the build-up of hot, damp air under the tarp was too uncomfortable: at night, at ground level, with no breeze, the humidity felt like a hundred per cent: his breath fogged the plastic.

Also the rakunks were a nuisance, scuffling through the leaves and sniffing at his toes, nosing around him as if he were already garbage; and one morning he’d woken to find three pigoons gazing in at him through the plastic. One was a male; he thought he could see the gleaming point of a white tusk. Pigoons were supposed to be tusk-free, but maybe they were reverting to type now they’d gone feral, a fast-forward process considering their rapid-maturity genes. He’d shouted at them and waved his arms and they’d run off, but who could tell what they might do the next time they came around? Them, or the wolvogs: it wouldn’t take them forever to figure out that he no longer had a spraygun. He’d thrown it away when he’d run out of virtual bullets for it. Dumb not to have swiped a recharger for it: a mistake, like setting up his sleeping quarters at ground level.

So he’d moved to the tree. No pigoons or wolvogs up there, and few rakunks: they preferred the undergrowth. He’d constructed a rough platform in the main branches out of scrap wood and duct tape. It’s not a bad job: he’s always been handier at putting things together than his father gave him credit for. At first he’d taken the foam mattress up there, but he had to toss it when it began to mildew, and to smell tantalizingly of tomato soup.

The plastic tarp on the lean-to was torn away during an unusually violent storm. The bed frame remains, however; he can still use it at noon. He’s found that if he stretches out on it flat on his back, with his arms spread wide and his sheet off, like a saint arranged ready for frying, it’s better than lying on the ground: at least he can get some air on all the surfaces of his body.

From nowhere, a word appears: Mesozoic. He can see the word, he can hear the word, but he can’t reach the word. He can’t attach anything to it. This is happening too much lately, this dissolution of meaning, the entries on his cherished wordlists drifting off into space.

“It’s only the heat,” he tells himself. “I’ll be fine once it rains.” He’s sweating so hard he can almost hear it; trickles of sweat crawl down him, except that sometimes the trickles are insects. He appears to be attractive to beetles. Beetles, flies, bees, as if he’s dead meat, or one of the nastier flowers.

The best thing about the noon hours is that at least he doesn’t get hungry: even the thought of food makes him queasy, like chocolate cake in a steam bath. He wishes he could cool himself by hanging out his tongue.

Now the sun is at full glare; the zenith, it used to be called. Snowman lies splayed out on the grillwork of the bed, in the liquid shade, giving himself up to the heat. Let’s pretend this is a vacation! A schoolteacher’s voice this time, perky, condescending. Ms. Stratton Call-Me-Sally, with the big butt. Let’s pretend this, let’s pretend that. They spent the first three years of school getting you to pretend stuff and then the rest of it marking you down if you did the same thing. Let’s pretend I’m here with you, big butt and all, getting ready to suck your brains right out your dick.

Is there a faint stirring? He looks down at himself: no action. Sally Stratton vanishes, and just as well. He has to find more and better ways of occupying his time. His time, what a bankrupt idea, as if he’s been given a box of time belonging to him alone, stuffed to the brim with hours and minutes that he can spend like money. Trouble is, the box has holes in it and the time is running out, no matter what he does with it.

He might whittle, for instance. Make a chess set, play games with himself. He used to play chess with Crake but they’d played by computer, not with actual chessmen. Crake won mostly. There must be another knife somewhere; if he sets his mind to it, goes foraging, scrapes around in the leftovers, he’d be sure to find one. Now that he’s thought of it he’s surprised he hasn’t thought of it before.

He lets himself drift back to those after-school times with Crake. It was harmless enough at first. They might play Extinctathon, or one of the others. Three-Dimensional Waco, Barbarian Stomp, Kwiktime Osama. They all used parallel strategies: you had to see where you were headed before you got there, but also where the other guy was headed. Crake was good at those games because he was a master of the sideways leap. Jimmy could sometimes win at Kwiktime Osama though, as long as Crake played the Infidel side.

No hope of whittling that kind of game, however. It would have to be chess.

Or he could keep a diary. Set down his impressions. There must be lots of paper lying around, in unburned interior spaces that are still leak-free, and pens and pencils; he’s seen them on his scavenging forays but he’s never bothered taking any. He could emulate the captains of ships, in olden times—the ship going down in a storm, the captain in his cabin, doomed but intrepid, filling in the logbook. There were movies like that. Or castaways on desert islands, keeping their journals day by tedious day. Lists of supplies, notations on the weather, small actions performed—the sewing on of a button, the devouring of a clam.
