Emma glared at Church. She knew the cat had once lived in the New York Institute, but it seemed rude to show preference so blatantly. The cat was lying on his back on Jace's lap, purring and ignoring her.
"Like an alarm," Julian said, "that goes off when you open a door?"
"Yes, but in this case, death is the open door," said Diana.
"So what's the solution?" asked Emma.
"We probably need his body to turn the spell off, so to speak," said Jace. "And a clue as to how he did it would be nice."
"The ruins of the convergence have been picked over pretty thoroughly," Clary said. "But we'll check out Malcolm's house tomorrow, just to be sure."
"It's rubble," Julian warned.
"Rubble that will have to be cleared away soon, before mundanes notice it," said Diana. "There's a glamour on it, but it's temporary. That means the site will only be undisturbed for another few days."
"And there's no harm taking a last look," said Jace. "Especially as Magnus has given us some idea what to look for." He rubbed Church's ear but didn't elaborate.
"The Black Volume is a powerful necromantic object," said Perfect Diego. "It could be causing disturbances we cannot even imagine. Driving the deepest-dwelling of sea demons to crawl up onto our shores means mundanes are in danger-a few have already disappeared from the Pier."
"So," said Jace. "A team of Centurions is going to arrive here tomorrow-"
"Centurions?" Panic flashed in Julian's eyes, a look of fear and vulnerability that Emma guessed was visible only to her. It was gone almost instantly. "Why?"
Centurions. Elite Shadowhunters, they trained at the Scholomance, a school carved into the rock walls of the Carpathian Mountains, surrounded by an icy lake. They studied esoteric lore and were experts in faeries and the Cold Peace.
And also, apparently, sea demons.
"This is excellent news," said Perfect Diego. He would say that, Emma thought. Smugly, he touched the pin at his shoulder. "They will be able to find the body and the book."
"Hopefully," Clary said.
"But you're already here, Clary," said Julian, his voice deceptively mild. "You and Jace-if you brought in Simon and Isabelle and Alec and Magnus, I bet you could find the body right away."
He doesn't want strangers here, Emma thought. People who would pry into the Institute's business, demand to talk to Uncle Arthur. He had managed to preserve the Institute's secrets even through everything that had happened with Malcolm. And now they were threatened again by random Centurions.
"Clary and I are only stopping by," Jace said. "We can't stay and search, though we'd like to. We're on assignment from the Council."
"What kind of assignment?" Emma said. What mission could be more important than retrieving the Black Volume, clearing up the mess Malcolm had made once and for all?
But she could tell from the look that Jace and Clary exchanged that there was a world of more important things out there, ones she couldn't imagine. Emma couldn't help a small explosion of bitterness inside, the wish that she were just a bit older, that she could be equal to Jace and Clary, know their secrets and the Council's secrets.
"I'm so sorry," Clary said. "We can't say."
"So you're not even going to be here?" Emma demanded. "While all this is going on, and our Institute is invaded-"
"Emma," Jace said. "We know that you're used to being alone and untroubled here. To having only Arthur to answer to."
If only he knew. But that was impossible.
He went on, "But the purpose of an Institute is not just to centralize Clave activity, but to house Shadowhunters who must be accommodated in a city they don't live in. There are fifty rooms here that no one is using. So unless there's a pressing reason they can't come . . ."
The words hung in the air. Diego looked down at his hands. He didn't know the full truth about Arthur, but Emma guessed that he suspected.
"You can tell us," Clary said. "We'll keep it in the strictest confidence."
But it wasn't Emma's secret to tell. She held herself back from looking at Mark or Cristina, Diana or Julian, the only others at the table who knew the truth about who really ran the Institute. A truth that would need to be hidden from the Centurions, who would be duty-bound to report it to the Council.
"Uncle Arthur hasn't been well, as I assume you know," Julian said, gesturing toward the empty chair where the Institute's head would normally have sat. "I was concerned the Centurions might worsen his condition, but considering the importance of their mission, we'll make them as comfortable as possible."
