“Where are they?” Toby asked.

“Some of them are here, with us,” said Pilar. She smiled. “Katuro the Wrench used to be an internist. He does our plumbing now. Surya was an eye surgeon. Stuart was an oncologist. Marushka was a gynecologist.”

“And the other doctors? If they aren’t here?”

“Let’s just say they’re safe, elsewhere,” said Pilar. “For the moment. But now you must promise me: those Corporation pills are the food of the dead, my dear. Not our kind of dead, the bad kind. The dead who are still alive. We must teach the children to avoid these pills – they’re evil. It’s not only a rule of faith among us, it’s a matter of certainty.”

“But how can you be so sure?” Toby asked. “The Corps – nobody knows what they’re doing. They’re locked into those Compounds of theirs, nothing gets out…”

“You’d be surprised,” said Pilar. “No boat was ever built that didn’t spring a leak eventually. Now, promise me.”

Toby promised.

“One day,” said Pilar, “when you’re an Eve, you’ll understand more.”

“Oh, I don’t think I’ll ever be an Eve,” said Toby lightly. Pilar smiled.

Later that same afternoon, when Pilar and Toby had finished the honey extraction and Pilar was thanking the hive and the queen for their cooperation, Zeb came up the fire-escape stairs. He was wearing a black fleather jacket of the kind favoured by solarbikers. They slashed those jackets to let the hot air circulate while they were riding, but there were extra slashes in this one.

“What happened?” said Toby. “What can I do?” Zeb’s tree-stump hands were clutched to his stomach; blood was coming out from between his fingers. She felt a little sick. At the same time she felt an urge to say, “Don’t drip on the bees.”

“Fell down and cut myself,” said Zeb. “Broken glass.” He was breathing heavily.

“I don’t believe that,” said Toby.

“Didn’t think you would,” said Zeb, grinning at her. “Here,” he said to Pilar. “Brought you a present. SecretBurger special.” He reached a hand into the pocket of his fleather jacket and brought out a fistful of ground meat. For a moment, Toby had the horrible impression that this was part of Zeb himself, but Pilar smiled.

“Thank you, dear Zeb,” she said. “I can always rely on you! Come with me, now, we’ll fix it up. Toby, could you find Rebecca and ask her to bring some clean kitchen towels? And Katuro. Him too.” She didn’t seem at all flustered by the sight of blood.

How old will I be, thought Toby, before I can be that calm? She felt cut open.

Pilar and Toby carried Zeb over to the Fallows Recovery Hut on the northwest corner of the Rooftop, which was used by Gardeners on Vigils, or those emerging from a Fallow state, or those who were moderately ill. As they were helping him to lie down, Rebecca came out from the enclosed shed at the back of the Rooftop, carrying a stack of dishtowels. “Now who did that?” she said. “That’s a glass job! Bottle fight?”

Katuro arrived, peeled the jacket off Zeb’s stomach, took a professional look. “Stopped by ribs,” he said. “Slash, not stab. No deep punctures – lucky.”

Pilar handed the ground meat to Toby. “It’s for the maggots,” she said. “Could you take care of it this time, dear?” The meat was already going off, from the smell of it.

Toby wrapped it in gauze from the Wellness Clinic as she’d seen Pilar do, and lowered the bundle over the edge of the rooftop on a string. In a couple of days, after the flies had laid their eggs and the eggs had had time to hatch, they’d haul it up again and harvest the maggots, because where there was rotting flesh, maggots were sure to follow. Pilar kept a supply of maggots always on hand for therapeutic use in case of need, but Toby had never seen them in action.

According to Pilar, maggot therapy was very ancient. It had been discarded as out of date along with leeches and bleeding, but during the First World War the doctors had noticed that soldiers’ wounds healed much faster if maggots were present. Not only did the helpful creatures eat the decaying flesh, they killed necrotic bacteria, and were thus a great help in preventing gangrene.

The maggots created a pleasant sensation, said Pilar – a gentle nibbling, as of minnows – but they needed to be watched carefully, because if they ran out of decay and began to invade the living flesh there would be pain and bleeding. Otherwise, the wound would heal cleanly.

Pilar and Katuro sponged Zeb’s cuts with vinegar, then rubbed on honey. Zeb was no longer bleeding, though he was pale. Toby got him a drink of Sumac.

Katuro said that pleebland street-fight glass was notoriously septic, so they should apply the maggots right away to avoid blood poisoning. Pilar used tweezers to place her stored maggots inside a fold of gauze, taping the gauze to Zeb. By the time the maggots had chewed through the gauze, Zeb would surely be festering enough to be attractive to them.

“Someone has to stay on maggot watch,” said Pilar. “Twenty-four hours a day. In case the maggots start to eat our dear Zeb.”

“Or in case I start to eat them,” said Zeb. “Land shrimp. Same body plan. Very nice fried. Great source of lipids.” He was keeping up a good front, but his voice was weak.

Toby took the first five hours. Adam One had heard about Zeb’s accident and came to visit. “Discretion is the better part of valour,” he said mildly.

“Yeah, well, there were too many of them,” said Zeb. “Anyway I put three of them in the hospital.”

“Not a thing to be proud of,” said Adam One. Zeb frowned.

“Foot soldiers use their feet,” he said. “That’s why I wear boots.”

“We’ll discuss this later, when you’re feeling better,” said Adam One.

“I’m feeling fine,” Zeb growled.

Nuala bustled in to take over from Toby. “Have you made him some Willow?” she said. “Oh dear, I hate those maggots! Here, let me prop you up! Can’t we raise the screening? We need a breeze through! Zeb, is this what you mean by Urban Bloodshed Limitation? You are so naughty!” She was twittering, and Toby felt like kicking her.

Lucerne arrived next, blotting tears. “This is terrible! What’s happened, who did…”

“Oh, he’s been so bad!” said Nuala conspiratorially. “Haven’t you, Zeb? Fighting with the pleeblanders,” she whispered delightedly.

“Toby,” said Lucerne, ignoring Nuala, “how serious is it? Will he… is he…” She sounded like some old-time TV actress playing a deathbed scene.

“I’m fine,” said Zeb. “Now buzz off and leave me alone!”

He didn’t want anyone fiddling with him, he said. Except Pilar. And Katuro, if absolutely necessary. And Toby, because at least she was silent. Lucerne went away, weeping angrily, but there was nothing Toby could do about that.

Rumour was the daily news among the Gardeners. The older boys heard quickly about Zeb’s battle – it had now become a battle – and the next afternoon Shackleton and Crozier came to see him. He was asleep – Toby had slipped some Poppy into his Willow tea – so they tiptoed around him, speaking in low voices and trying for a peek at his wound.

“He ate a bear once,” said Shackleton. “When he was flying for Bearlift, that time they were trying to save the polar bears. His plane crashed and he walked out – it took months!” The older boys had many such heroic tales about Zeb. “He said bears look just like a man when they’re skinned.”

“He ate the co-pilot. After he was dead, though,” Crozier said.

“Can we see the maggots?”

“Has he got gangrene?”

“Gang! Grene!” shouted little Oates, who’d tagged along after his brothers.

“Shut up, Oatie!”

“Ow! You meat-breath!”

“Off you go now,” said Toby. “Zeb – Adam Seven needs his rest.”

Adam One persisted in thinking that Shackleton and Crozier and young Oates would turn out just fine, but Toby had her doubts. Philo the Fog was supposed to be their stand-in father, but he wasn’t always mentally available.
