“Wells was a sacrifice,” said Julian. “So it stands to reason that the other eleven murders have been because of this cult too.”

“It also explains the fey bodies,” said Cristina. “Since so many of them are half-fey, it makes sense that they’ve been picked for the sacrifices.”

Julian glanced at Mark. “Do you think the Courts know if the bodies were half-fey or full-blooded?”

“Hard to say,” said Mark, still staring at the cat. “They often cannot tell just by looking, and some of the Followers are full-blood faeries.”

“It seems like full-blood faeries would have better things to do.” It was Ty, having pulled the headphones from his ears. Emma could faintly hear classical music drifting from them. “Why would they join something like this?”

“It is a place for lost souls,” said Mark. “And since the Cold Peace, many of the Fair Folk are lost. It makes sense.”

“I saw them advertising at the Shadow Market,” said Emma. “I saw Belinda there too. They seemed to be specifically looking for anyone with the Sight, anyone who seemed frightened or alone. Having a group to belong to, being promised good luck and wealth, getting strength from the sacrifices—you can see how it would be appealing.”

“They do seem very confident,” Cristina said. “How much do they know about the existence of Nephilim, I wonder?”

“Sterling seemed afraid of us,” said Emma. “It’s weird. He got picked, so that means they’re going to sacrifice him. You’d think he’d want any help he could get, even from Shadowhunters.”

“But getting help is forbidden, right?” said Livvy. “If they caught him accepting it, they could torture him. Do worse than kill him.”

Cristina shuddered. “Or he could be a true believer. Maybe he thinks it would be a sin to accept help.”

“Men have gone to their deaths for less,” said Mark.

“How many of them do you think there were? The Followers?”

“About three hundred,” said Julian.

“Well, if we can’t go to the faeries yet, we’ve got two options,” said Emma. “One, we track down every one of those three hundred losers and beat them up until they tell us who did the actual killing.”

“That seems impractical,” said Ty. “And time-consuming.”

“Or we could go straight to finding out who the leader is,” Emma said. “If anyone knows, it’s that Belinda girl.”

Julian ran a hand through his hair. “Belinda’s not her real name—”

“I’m telling you, Johnny Rook knows her,” Emma said. “In fact, he probably knows a lot, given that information about the Shadow World is his business. We’re asking him.”

“Yes, you agreed to this already in the car,” Mark said, and frowned. “This cat is looking at me with judgment.”

“He’s not,” said Jules. “That’s just his face.”

“You look at me the same way,” Mark said, glancing at Julian. “Judgy face.”

“This is still progress,” Livvy said stubbornly. She glanced at Mark sideways, and Emma saw anxiety in her gaze. It was so rare for Livvy to show the worry she felt that Emma sat up straight. “We should go to the faerie convoy, tell them the Followers are responsible—”

“We can’t,” said Diana, appearing in the doorway. “The fey were very specific. ‘The one with blood on his hands.’ You might think they want progress reports, but I don’t think they do. They want results, and that’s all.”

“How long have you been eavesdropping?” Julian asked, though there was no hostility in the question. He glanced at his watch. “It’s awfully late for you to be here.”

Diana sighed. She did look bone weary. Her hair was untidy and she was uncharacteristically dressed down in a sweatshirt and jeans. There was a long scrape across one of her cheeks.

“I went by the convergence on my way back from Ojai,” she said. “I got in and out fast. Only had to kill one Mantid.” She sighed again. “It doesn’t look like anyone’s been back there since the night you went. I’m worried our necromancer’s found a new place.”

“Well, if he doesn’t use a convergence, the next time he uses dark magic, he’ll show up on Magnus’s map,” said Ty.

“Did you find anything useful in Ojai?” Emma asked. “What warlock is up there? It’s not anyone we know, is it?”

“No.” Diana leaned against the doorjamb, clearly not planning on saying anything else. “I did hear about the Followers; I suppose I shouldn’t be surprised you were tracking them down here. I wish you’d told me, but—”

“You’d already left,” said Jules. He leaned back on his hands. His dress shirt stretched across his chest. Knowing what his body looked like under the cotton was not helping Emma’s concentration. She looked away, hating her uncontrolled thoughts. “But I can give you the summary.”

As he started to talk, Emma quietly turned and walked out of the room. She could hear Julian’s voice behind her, recounting the events of the evening. She knew he’d tell the story exactly right; she knew she didn’t have to worry. But right now there were two people she urgently needed to talk to, and she needed to do it alone.
