A small light of curiosity shone in Kitteredge’s eyes. “So you’re a son of Vidocq?” he said.

If it hadn’t been for those weeks in Kitteredge’s class, Gus might have been thrown by a reference to someone he’d never heard of. But if he’d learned anything in the course, it was that there were huge amounts of things he’d never heard of-and that Kitteredge not only had heard of most of them but could always find ways to work them into conversation. He’d watched other students flounder helplessly as they dug for definitions of random phrases while the lecture went on above their heads. So he chose to handle this one the way he had the others-by ignoring it and moving on to the main point. “What exactly is going on here?”

“Something terrible,” Kitteredge said sadly. “I fear the worst.”

“And the worst would be…?”

“That.”

Kitteredge leveled a heavy finger at the museum entrance, where a uniformed officer was accompanying a tall, skinny man in a tuxedo out of the lobby. The man shook so hard he could barely stand up; he dabbed at the corners of his mouth with a handkerchief in a way that suggested most of his energy was going into not throwing up.

The officer marched over to Lassiter. “We’ve secured the scene,” he said. “There’s no one inside.”

“Thank you, Officer,” Lassiter said. “In that case, let us proceed to see the body.”

At the word “body,” the thin man shuddered violently and for a moment looked like he was going to crumple to the ground. But Kitteredge reached out and put a comforting hand on his shoulder, and he managed to steady himself.

“Do I need to go back in there?” the thin man said. “I mean, if it will help, I’m ready to. But I don’t know what else I can do. I told the officer everything I knew about poor Filkins.”
