It takes the maggots three days to clean the wound. Toby watches them carefully: if they run out of dead tissue, they’ll start in on living flesh.

By the second morning Ren’s fever has gone, though Toby continues the mushroom drops just to make sure. Ren’s eating more now. Toby helps her up the stairs to the roof and sits her down on the imitationwood bench, in the early morning light. The maggots are photophobic: light drives them into the deepest corners of the wound, which is where they need to be.

No movement out there in the meadow. No sounds from the forest.

Toby tries asking Ren where she’s been ever since the Flood hit, and how she escaped it, and how she got here, why she’d been dressed in those blue feathers; but she only tries once because Ren starts crying. All she’ll say is, “I’ve lost Amanda!”

“Never mind,” says Toby. “We’ll find her.”

On the fourth morning Toby removes the maggot plaster: the wound is clean, and healing. “Now to get your muscles back in shape,” she tells Ren.

Ren starts walking, up and down the stairs, along the corridors. She’s gained a little weight: Toby’s been feeding her the last few jars of AnooYoo Lemon Meringue Facial, which has a lot of sugar in it and nothing toxic that Toby can think of. She leads Ren through some exercises from Zeb’s old Urban Bloodshed Limitation classes – the satsuma, the unagi. Centred like a Fruit, sinuous like an Eel. She needs the refresher herself; she’s out of practice.

After a few days Ren tells her story, or a little of her story. It comes out in short clumps of words punctuated by long periods of staring into space. She tells about being locked in at Scales, and how Amanda came all the way from the Wisconsin desert and figured out the door code. Then Shackie and Croze and Oates appeared from nowhere, just like magic, and she was so happy – they’d been saved by being in Painball when the plague broke out. But then three horrible men from the Painball Gold Team came to Scales, and she and Amanda and the boys ran away. She’d said they should come to AnooYoo because Toby might be there, and they’d almost made it – they were walking along through the trees, and then blackout. She can’t get any farther than that.

“What did they look like?” says Toby. “Did they have any…” She wants to say “distinguishing marks,” but Ren shakes her head, meaning that that subject is closed. “I have to find Amanda,” she says, wiping away tears. “I really have to. They’ll kill her.”

“Here, blow your nose,” says Toby, handing her a pink washcloth. “Amanda’s very clever.” It’s best to talk as if Amanda is still alive. “She’s very resourceful. She’ll be all right.” She’s about to say that women are in short supply and therefore Amanda will surely be preserved and rationed, but she thinks better of it.

“You don’t understand,” says Ren, crying harder. “There’s three of them, they’re Painball – they’re not really human. I have to find her.”

“We’ll look,” Toby says, to be soothing. “But we don’t know where they – where she’s gone.”

“Where would you go?” says Ren. “If you were them?”

“Maybe east,” says Toby. “To the sea. Where they could fish.”

“We can go there.”

“When you’re strong enough,” says Toby. They have to move somewhere else anyway: the food supply’s shrinking fast.

“I’m strong enough now,” says Ren.

Toby scours the garden, unearths one more lone onion. She digs up three burdocks from the near edge of the meadow, and some Queen Anne’s lace – the spindly white proto-carrot roots. “Do you think you could eat a rabbit?” she asks Ren. “If I cut it up very small and make it into soup?”

“I guess so,” said Ren. “I’ll try.”

Toby’s almost ready for the switch to full-blown carnivore herself. There’s the sound of the rifle shot to worry about, but if there are still Painballers lurking in the forest they already know she has a gun. No harm in reminding them.

There are often green rabbits near the swimming pool. Toby shoots at one of them from the rooftop, but she can’t seem to hit it. Is conscience twisting her aim? Maybe she needs a bigger target, a deer or a dog. She hasn’t sen the pigs lately, or any of the sheep. Just as she was getting all set to eat them, they’re gone.

She locates the packsacks on a laundry-room shelf. She hasn’t been down there since the pumps stopped working, and the air’s thick with mildew. Luckily the packsacks aren’t cotton but impenetrable synthetic. She takes them up to the roof, sponges them off, leaves them in the hot sun to dry.

She lays out her available supplies on the kitchen counter. Don’t carry so much weight that you burn more calories than you can eat, says the voice of Zeb. Tools are more important than food. Your best tool is your brain.

The rifle, of course. Ammunition. Trowel, for digging roots. Matches. Barbecue lighter, which won’t last long but it might as well be used up. Pocket knife with scissors and tweezers. Rope. Two sheets of plastic, handy in rain. Windup flashlight. Gauze bandages. Duct tape. Plastic snap-top containers. Cloth bags for wild edibles. Cooking pot. The Kelly kettle. Toilet paper – a luxury item, but she can’t resist. Two medium-sized Zizzy Froots from a Spa minibar, raspberry flavour: junk food, but food, since it has calories in it. The bottles can be used later, for water.

Spoons, metal, two; cups, plastic, two. The remaining sunblock. The last SuperD bug spray. Binoculars: heavy but necessary. The mop handle. Sugar. Salt. The last of the honey. The last Joltbars. The last soybits.

The syrup of Poppy. The dried mushrooms. The Death Angels.

The day before they leave, she cuts her hair short. It’s a shorn look – it reminds her of Joan of Arc on a bad day – but she doesn’t want a hair handle growing out of her head, all the better to grab you by and slash your throat. She cuts Ren’s hair as well. They’ll be cooler that way, she tells her.

“We should bury the hair,” says Ren. She wants it out of sight for some reason Toby can’t fathom.

“Why don’t we put it on the roof?” says Toby. “That way the birds can make nests out of it.” She doesn’t intend to waste her body’s calories digging a hair burial site.

“Oh. Okay,” says Ren. This idea seems to please her.
