“You must be the other son of Vidocq,” he said.

“I’m Shawn Spencer,” Shawn conceded. “But if you’re suggesting that my father was a space probe that was granted consciousness by an alien entity and now roams the universe eating planets, well, you’re only part right.”

“That’s V’ger,” Gus said.

The professor didn’t seem to notice Shawn’s misunderstanding. “Of course you know I’m referring to Eugene Francois Vidocq, the former French soldier, criminal, and privateer who in 1833 founded Le Bureau de Reseignements Universels pour le commerce et l’industrie, the world’s first private detective agency,” he said. “He’s mostly remembered for introducing record keeping and ballistics into the science of crime solving, along with being the first to make plaster casts of shoe impressions. But what I find singular about the man was his sense of compassion. Although there is no proof that this is true, he famously boasted that he never turned in to the police anyone who claimed to have stolen out of need.”

“Of course we know that,” Shawn said. “I’ve even got it on a T-shirt. Well, not the whole thing, because that wouldn’t fit. In fact, I think it actually says ‘Frankie Says Relax,’ but those who are in the know understand. Anyway, why’d you kill this guy?”

“I can assure you I have killed no one,” Kitteredge said. Then his face darkened. “But I do fear that someone has died because of me. Because of what I’ve found out. I’ve been concerned this would happen for a very long time, but I always assumed I would be the target.”

“That’s why you sent me the letter,” Gus said. He fished the document out of his breast pocket and shook it open. “That’s what you meant when you said ‘These are dark and difficult times. Events are conspiring to bring an end to those things which we hold most dear.’ ”

“Umm, no, not exactly,” Kitteredge said. “But now that I see what’s happened, I might wish it was the case.”
