Terry looked at the map. “Do you want to know where I was sitting or where she was sitting? Because I remember she was sitting next to the window here. And I probably was sitting here; clear across to the other side.”

“So you were sitting closer to the reference desk and Angeline’s table was the farthest from the reference desk.”

“Whatever you say.”

“I’m not saying, I’m asking. Look at the map and tell me if I’m right?”

Terry glanced at the rudimentary drawing. “Yeah, sure. That looks about right.”

“Could you see what she was doing?” Decker asked.

“I assumed she was looking at the book.”

“Let me ask it this way,” Decker said. “Was she in your direct line of vision?”

“Because it doesn’t look that way from my map,” McAdams said.

“I guess if I had been paying attention to her, I could have seen what she was doing. But I wasn’t. Why are you asking all these questions?”

Decker said, “Her thesis was on textiles, not icons. Why would she want a book on iconography? Did you ask her about it?”

“No. I didn’t ask her about it. Why would I care?” Terry looked at McAdams. “You said the book was valuable. Did she take it? Is that why she was killed?”

McAdams looked at Decker who said, “The book is still in the library. But some of the original plates have been stolen and replaced with forgeries.”

“Just like the Tiffany windows,” Sobel said.

Decker nodded.

“She’s the connection, right?”

“Jury is still out.” Decker quickly scanned his notes and then he looked at Terry. The thefts of the art plates didn’t seem to come as a shock to him from the expression on his face. “Thanks for seeing us, Lance. I may have a few more questions later on.”

“If you do, call instead.”

“Some conversations are better in person.”

“You didn’t have to sneak up like you did. I would have told you about the book in the first place, but I didn’t remember. There was no reason to terrorize the doorman.”

“We didn’t terrorize anyone,” McAdams said. “Besides, this is the Upper East Side. He’s dealt with far worse than us.”

“I have a question.” Sobel pointed to McAdams. “I see what happened to you. Am I in danger?”

Terry looked up and down and didn’t say anything. Decker raised his eyebrows. “Is there something you’d like to say to me?”

“Me? No . . . I mean, yeah. Are we safe?” Terry’s voice grew loud. “This is just terrific. Another legacy that the bitch left behind.”

“Are you sure you don’t have anything to tell me?”

“No,” Terry said.

“You never answered my question,” Sobel said.

“I wish I had an answer,” Decker said. “I’m carrying a gun. So is Detective Oliver. My wife is carrying a gun and has a full-time armed bodyguard.”
