She lowered her voice. “Will everyone there—does everyone know about my father?”

“Oh, no. Very few people have heard any details, and those are being quite closemouthed about it.” Lucie eyed her speculatively. “Would you be willing—if you told me what happened, I swear I would not share it with a soul, not even James.”

Cordelia’s chest hurt, as it always did when she thought about her father. But she must tell this to Lucie nevertheless, and she would need to tell it to others, too. She would not be able to help her father unless she was straightforward in demanding what she wanted. “About a month ago, my father went to Idris,” she said. “It was all very secret, but a nest of Kravya¯d demons had been discovered just outside the border of Idris.”

“Really?” said Lucie. “They’re nasty ones, aren’t they? Man-eaters?”

Cordelia nodded. “They had wiped out nearly a whole pack of werewolves. It was the wolves, actually, who brought the news to Alicante. The Consul put together an expeditionary force of Nephilim and called in my father because of his expertise with rare demons. Along with two of the Downworlders, he helped plan the expedition to slay the Kravya¯ds.”

“That sounds very exciting,” said Lucie. “And how wonderful, to be working with Downworlders like that.”

“It ought to have been,” said Cordelia. She glanced back; James was a good distance away, still reading. He couldn’t possibly hear them. “The expedition went wrong. The Kravya¯dād demons had gone—and the Nephilim had trespassed onto land that a vampire clan believed was theirs. There was a fight—a bad one.”

Lucie paled. “By the Angel. Was anyone killed?”

“Several Nephilim were injured,” said Cordelia. “And the vampire clan believed that we—that the Shadowhunters—had allied with the werewolves to attack them. It was a terrible mess, something that could have undone the Accords.”

Lucie looked horrified. Cordelia didn’t blame her. The Accords were a peace agreement between Shadowhunters and Downworlders that helped maintain order. If they were broken, bloody chaos could ensue.

“The Clave launched an investigation,” Cordelia said. “All right and proper. We thought my father was meant to be a witness, but he was arrested instead. They are blaming him for the expedition having gone wrong. But it was not his fault. He couldn’t have known—” She closed her eyes. “It nearly killed him, having let down the Clave so badly. He will have to live with the guilt all his life. But none of us expected them to end the investigation and arrest him instead.” Her hands were shaking; she laced them tightly together. “He sent me one note, but nothing after that: they forbid it. He is being held under house arrest in Alicante until his trial can take place.”

“A trial?” said Lucie. “Just for him? But there were others in charge of the expedition as well, weren’t there?”
