In the early morning Toby climbs up to the rooftop to watch the sunrise. She uses a mop handle for balance: the elevator stopped working some time ago and the back stairs are slick with damp, so if she slips and topples there won't be anyone to pick her up. As the first heat hits, mist rises from among the swathe of trees between her and the derelict city. The air smells faintly of burning, a smell of caramel and tar and rancid barbecues, and the ashy but greasy smell of a garbage-dump fire after it's been raining. The abandoned towers in the distance are like the coral of an ancient reef--bleached and colourless, devoid of life. There still is life, however. Birds chirp; sparrows, they must be. Their small voices are clear and sharp, nails on glass: there's no longer any sound of traffic to drown them out. Do they notice that quietness, the absence of motors? If so, are they happier? Toby has no idea. Unlike some of the other Gardeners--the more wild-eyed or possibly overdosed ones--she has never been under the illusion that she can converse with birds. The sun brightens in the east, reddening the blue-grey haze that marks the distant ocean. The vultures roosting on hydro poles fan out their wings to dry them, opening themselves like black umbrellas. One and then another lifts off on the thermals and spirals upwards. If they plummet suddenly, it means they've spotted carrion. Vultures are our friends, the Gardeners used to teach. They purify the earth. They are God's necessary dark Angels of bodily dissolution. Imagine how terrible it would be if there were no death!Do I still believe this? Toby wonders. Everything is different up close.

The rooftop has some planters, their ornamental running wild; it has a few fake-wood benches. It used to have a sun canopy for cocktail hour, but that's been blown away. Toby sits on one of the benches to survey the grounds. She lifts her binoculars, scanning from left to right. The driveway, with its lumirose borders, untidy now as as frayed hairbrushes, their purple glow fading in the strengthening light. The western entrance, done in pink adobe-style solarskin, the snarl of tangled cars outside the gate. The flowerbeds, choked with sow thistle and burdock, enormous aqua kudzu moths fluttering above them. The fountains, their scallop-shell basins filled with stagnant rainwater. The parking lot with a pink golf cart and two pink AnooYoo minibuses, each with its winking-eye logo. There's a fourth minibus further along the drive, crashed into a tree: there used to be an arm hanging out of the window, but it's gone now.The wide lawns have grown up, tall weeds. There are low irregular mounds beneath the milkweed and fleabane and sorrel, with here and there a swatch of fabric, a glint of bone. That's where the people fell, the ones who'd been running or staggering across the lawn. Toby had watched from the roof, crouched behind one of the planters, but she hadn't watched for long. Some of those people had called for help, as if they'd known she was there. But how could she have helped? The swimming pool has a mottled blanket of algae. Already there are frogs. The herons and the egrets and the peagrets hunt them, at the shallow end. For a while Toby tried to scoop out the small animals that had blundered in and drowned. The luminous green rabbits, the rats, the rakunks, with their striped tails and racoon bandit masks. But now she leaves them alone. Maybe they'll attract fish, somehow.Is she thinking of eating these future fish? Surely not. Surely not yet.She turns to the dark encircling wall of trees and vines and fronds and shrubby undergrowth, probing it with her binoculars. It's surely from there that any danger might come. But what...
