I reach the kitchen. Dervish is hard at work on the steak. “No!” he shouts before I say anything. “She hasn’t rung and there’s been no sign of her. Now stop pestering me or I might—”

“We have company,” I interrupt.

Dervish turns questioningly. The woman enters the kitchen. I step aside so he can see her. Instant recognition. His face goes white, then red. He steps away from the hob, abandoning the steak. Eyes tight. Lips quivering. With anger.

“You!” He spits the word out.

“It’s been a long time, Dervish,” the woman says softly, not moving forward to shake his hand. “You look better than I expected.”

“I thought she was David A. Haym,” I tell him.

“She’s not,” he barks. “She’s Prae Athim.”

“Pray at him?” I echo.

“Pray Ah-teem,” the woman says, stressing the syllables.

“She’s one of the Lambs,” Dervish says with a sneer.

And the fear which was tickling away at me in the car kicks in solid, like a nail being hammered into my gut.

In Dervish’s study. Like most of the rooms, it’s huge. But whereas the others have bare walls, with stone or wood floorboards, the study is carpeted and the walls are covered with leather panels. There are two large desks, bookcases galore, a PC, laptop, typewriter, paper and pens. There used to be five chess sets, but not any more. The swords and axes which hung from the walls are gone too.

Prae Athim doesn’t want me here. That’s obvious from her disapproving look. Dervish doesn’t care. He’s seated behind the computer on his largest desk, one hand on the mouse, moving it around in small circles, waiting for his unwelcome guest to speak. Prae Athim is seated opposite. I’m standing close to the door, ready to leave if Dervish tells me to.

Prae finally speaks. “Billy Spleen still lives with his grandparents?” Dervish nods slowly. “I thought you might have moved him in with you. To observe.”

“You’re the master observer, not me,” Dervish says quietly.

“Isn’t it dangerous, leaving him there?” she presses.

“Billy’s time of turning has passed. There’s nothing to fear from him now.”

“That’s debatable,” Prae smiles.

“No. It isn’t.”

Prae looks at her hands crossed over her lap. Thinks a moment. Then nods at me. “I’d rather not speak in front of the boy.”

“Is this about him?” Dervish responds.

“Partially.”

“Then you’ll have to.”

“I really don’t think—” she begins.

“Grubbs faced the demons with me,” Dervish interrupts. “He fought by my side. I’m not going to keep secrets from him.”

“Really?” Prae sniffs. “You tell him everything about your business?”

“No. But I don’t hide things from him. When he asks, I answer. And since I’m certain he’s going to be asking about this, he might as well stay and hear it first-hand.”

Prae sighs. “You never make life easy for us. You’ve always treated the Lambs like enemies. We’re on the same side, Dervish. You should afford us respect.”

“I do respect you,” Dervish says. “I just don’t trust you.”

I’d forgotten about the Lambs. They loomed large in my thoughts while Dervish was zombified, especially around the time of a full moon. If I’d found myself turning into a werewolf, I was going to phone them and ask them to put me out of my misery. But since Dervish returned, I haven’t had time to brood about my potentially fatal genes or the family bogey men.

The Gradys and their kin have been cursed for a long time. We’re talking a lot of generations. Over the centuries, family members have tried to figure out the cause of the curse, find a cure for it, and develop ways of dealing with the infected children quietly and efficiently.

The Lambs are the result. A group of scientists, soldiers and I don’t know what else, all focused on the problems and logistics of lycanthropy. They spend a lot of time, money and effort trying to unlock the secrets of the rogue Grady-genes. But they also play the part of executioners when necessary.

A lot of parents decide to kill their children if they turn into werewolves. But most can’t perform the dirty deed themselves. So they call in the Lambs, who take the transformed child away and do what must be done.

“How did you find out about Billy?” Dervish asks.

“We keep tabs on all the family children,” Prae says.

“But Billy didn’t leave a trail. There was no evidence that he was turning.”

Prae smiles. “You covered up admirably. Gathered the bodies of the animals he slaughtered, disposed of them quietly. But you couldn’t be expected to find every corpse. And you couldn’t do anything about the operative who saw him sneaking out of his house during a full moon.”

“You had him under direct surveillance?” Dervish snaps.

“Sometimes, yes.”

Dervish’s hand goes rigid on the mouse. “You had no right to do that.”

“We had every right,” Prae disagrees. “If a guardian chooses to deal personally with an infected child, it’s not our business. But you didn’t. You gave him free reign.”

“I was in control,” Dervish growls. “He wasn’t a danger to anyone. I was waiting for the right moment to act.”

“I understand,” Prae says. “But we couldn’t take any chances. We guessed you would handle the matter this way if he turned, so for some years we’d been keeping an eye on the boy. On your brother’s children too.”

Dervish starts to retort. Stops and scowls. “Tell me why you’ve come.”

“A few reasons,” Prae says. “One—to make sure Billy is normal.”

“He is,” Dervish says. “We cured him.”

“But how certain is your cure?” Prae asks. “We know about the demon you deal with, but there’s much about the process that’s a mystery. You and the others who have faced him keep it a secret. You don’t let the rest of us benefit.”

“We can’t include you,” Dervish says stiffly. “He deals with one case at a time, and only with those who have some experience of magic. That’s how it works. It’s not our choice—it’s his.”

“The demon,” Prae nods. “Lord—”

“Don’t say his name here,” Dervish stops her. “It’s dangerous.”

Prae looks around nervously. I feel the hairs rise on the back of my neck. Then Dervish catches my eye and tilts his head ever so slightly. It’s a gesture I know well—he does that sometimes instead of winking. I realise he’s winding Prae up, giving her a scare. I hide a smile behind my hand and wait for her to settle down.

“It’s not fair,” Prae resumes, less composed than before. “We’ve never had any contact with the demon. Maybe we could strike our own deal if you put us in touch with him.”

“You couldn’t.”

“But you should let us try. We—”

“We’ve had this conversation before,” Dervish interrupts. “We’re not having it again. The Lambs follow the path of science. Demons are creatures of magic. The two don’t mix. End of story.”

“Very well,” Prae says, showing open anger for a second, her pale face flushing. “You choose to lock us out—there’s nothing we can do about that. But it means we don’t know all that we should about the cure. We have no proof that it works in the long term, or why. So it’s natural for us to be suspicious, to run our own checks, to be safe.”

“Totally natural,” Dervish says sarcastically. “But I don’t think you’d have waited until now to make sure Billy wasn’t killing. If you were checking on him prior to his change, I’m sure you’ve monitored him in the year-plus since. So your first reason for being here is a crock—you know Billy’s fine. Let’s move on to reason two and try to make it a bit more believable this time.”

Prae glares at Dervish, then glances at me. “Two,” she growls. “We wanted to check on Grubbs. He’s at a dangerous age. Both his brother—” My stomach tightens another notch. She knows the truth about Bill-E! “—and sister turned. We thought it advisable to have a look at him. We kept out of the way while you were… indisposed, but now that you’re back on your feet, we felt it was a good time to have a chat.” She faces me and smiles. “How have you been sleeping lately? Any bad dreams? Woken up with dirt under your fingernails or—”
