said that we did not know the extent of what it could do.”
“When I landed in the greenhouse, I’d no idea where I was,” he said. “I was choking on dust. White-gray dust, like burnt bones. I brought a handful of the stuff back from the other world—” He reached into his trouser pocket and brought out a pinch of what looked like ash. “I am going to bring it to Henry and Christopher. Perhaps they can test what is in it. I have never been able to bring anything back from the shadow realm before; perhaps it happened because I went into the realm willingly.”
“Do you think it’s because I was fighting the demon—with Cortana—that you were drawn to this place?” she said. “Whatever kind of demon it was—”
James glanced again at the greenhouse. “It was a Cerberus demon. And it’s probably been here for years.”
“I’ve seen pictures of Cerberus demons before.” Cordelia wobbled to her feet. James rose and put his arm around her to steady her. She tensed at his nearness. “They don’t look like that.”
“Benedict Lightwood was a great enthusiast for demons,” said James. “When they cleared this place out after he died, they found a dozen Cerberus demons. They’re watchdog creatures; he’d placed them here to protect his family and property. I suppose they missed the one in the greenhouse.”
Cordelia moved away from James slightly, though it was the last thing she wanted to do. “And you think over the years, it changed? Became more a part of the place?”
“Have you read On the Origin of Species?” asked James. “It is all about how animals adapt to their environments through generations. Demons don’t have generations—they don’t die, unless we kill them. This one adapted to its surroundings.”
“Do you think there are more around?” The raw pain in Cordelia’s ankle had faded to a manageable ache as she twisted around, looking up and down the garden for Lucie. “We could be in danger. Lucie—”
James went white. “Lucie?”
Cordelia’s heart skipped a beat. By the Angel. “Lucie and I came here together.”
“Of all the foolish—” Suddenly he was worried. She could see it in his face, his eyes. “Why?”
“Lucie wanted to make sure Grace was all right, and she asked me to come with her,” lied Cordelia. “In fact, she went into the house, where Grace and Tatiana are. Rather foolishly, I wandered off to see the gardens.…”
An odd look of utter shock passed across James’s face, as if he had just remembered something terribly important.
“Grace,” he said.
“I know you might wish to go see her,” said Cordelia. “But I must warn you that Tatiana is in a very bad mood.”
James continued to look silently stunned. There was a rustle of noise and Lucie burst out of the overgrowth.
“Cordelia!” she gasped, her face lighting with relief. “And Jamie!” Her face wrinkled up; she came to a dead stop. “Oh, dear. Jamie. What are you doing here?”
“As if you have a perfectly reasonable excuse for lurching about someone else’s property in the dead of night?” James said, transforming from a worried young man into a towering older brother in a matter of seconds. “Papa and Mam are going to murder you.”
“Only if you tell them.” Lucie’s eyes flashed. “How else are they going to find out?”
“Of course they will,” said James darkly. “The existence of a Cerberus demon in the greenhouse could hardly—”
Lucie’s eyes rounded. “A what in the where?”
“Cerberus demon in the greenhouse,” James repeated, “where, incidentally, you sent your future parabatai completely alone—”
“Oh, no, it’s all right, I went in on my own,” Cordelia said, and started. “I was going to move the carriage from the gates. If Tatiana looks out a window and sees it, she’ll be furious.”
“We’d better go,” Lucie said. “James, will you be coming with us or going back the way you came?” She squinted. “What is the way you came?”
“Never you mind,” said James, with his crooked smile. “Go take the carriage. I’ll follow along shortly and see you both at home.”

“I imagine James is staying because he wants to see Grace,” Lucie said in a low voice as she and Cordelia hurried back along the overgrown pathways of the Chiswick House gardens. They ducked through the gates and found the carriage exactly where it had been before, Xanthos seeming to stand guard. “Moon around under her window or whatever. I hope Tatiana doesn’t bite off his head.”
“She certainly doesn’t seem to want visitors,” said Cordelia as they clambered into
