“But she could be stealing . . . taking old prints and maps out of books by razoring them at the binding.”

“Again, not Audubon. Ever see a copy of his original book? I think his plates were like two feet by four feet.”

“So not Audubon. Maybe someone not as valuable or big.”

“Possibly.”

“Or,” Decker said, “maybe she was stealing outright: rare manuscripts or books. After you’re rested, I want you to check out the local libraries at the Upstate colleges and see if some of their old atlases have been messed with or see if any rare books are missing.”

“I should start writing this down.” He took out his tablet. “Find the names of original detectives in the Nikolai Petroshkovich theft, talk to the Upstate colleges’ librarians and see if any rare books are missing, check out antique reference material and see if maps or prints are missing . . . what else did you ask me to do? I’m a little fried right now.”

“Expand your search for other smaller local art thefts.”

“Right.”

“Now for the crucial question. How do we link the murders to the Tiffany theft? Just blurt out the first thing that comes to mind, Tyler.”

“I’m not a good blurter outer, Decker. I’m more the well-placed zinger type.”

Decker sighed and didn’t respond.

“Right, just shut up and answer the question. Okay. I’m gonna say that since you made copies of the keys that you found at Latham’s apartment, you’re going to valiantly attempt to open some storage locker with the faint hope that it holds the stolen Tiffany panels or other objets d’art.”

“That is an avenue of exploration, yes. But unless Summer Village PD turns up a bill to a specific storage facility, that’s a long shot. Let’s go back to the beginning. If we assume a connection—murders and thefts—how did Angeline and Latham find out about the Tiffany panels in the first place?”

“Maybe they’re professional grave robbers and they hit upon the panels by luck.”

“Are those items or any items in a cemetery worth butchering two people?”

“Is anything in cemeteries worth butchering two people like that?” The kid thought a moment. “Perhaps. Just look at King Tut.”

Decker couldn’t help it. He laughed. “How about we stick to American cemeteries?”

McAdams smiled. “No, it is not likely that Angeline and Latham were murdered for items they pilfered from local cemeteries.”

“Right now, we’re working on the theory that someone hired them to rob the mausoleum. So how did Angeline and Latham discover the panels in the first place?”

“They were told by the person who hired them to steal them?”

“And how did the person find out?”

“That’s actually a very good question,” McAdams said. “Because according to my research, they haven’t been featured in an art book or loaned out for any museum exhibit.”
