“I’ve been mulling several options in my head.” He ticked them off. “I’m keeping you awake so you don’t fall asleep at the wheel, I can drive home in case you do get too sleepy, you want me close so I don’t fuck something up in your absence, or maybe, just maybe, I may actually be of some use to the investigation and you value my opinions.”

“Bang on the money, Harvard.”

“Admit it, Old Man. I’m growing on you.”

“Mea culpa.”

“Yeah, I’m kind of like lutefisk: strictly an acquired taste.” McAdams put the coffee cup in the holder and rubbed his hands together. “I could tell by your conversation with the mom that Angeline did stained glass. So that makes her a strong candidate for the Tiffany forgeries. The thefts must have something to do with her murder.”

“Maybe.”

“Are you just being cagey or is that a sincere maybe.”

“This is what I think. The thefts weren’t what caused her problems . . . it was you and me uncovering the thefts. Someone wanted to silence her. But do I really believe that someone would murder over a few Tiffany panels? Doubtful. We’re dealing with something bigger . . . no offense to Tiffany . . . or Clara Driscoll.”

“Who’s that?”

“Karen Bronson, Angeline’s mother, told me that Angeline like stained glass because Clara Driscoll, a woman who worked for Tiffany, actually made a lot of the designs.”

“Hold on, let me look her up.” McAdams took out his iPhone. “It may take a minute. I think we’re in a dead zone.” He looked up. “For the phone, I mean. My brain, that’s another story . . . what’s it going on without sleep? Like thirty hours? How do you think, let alone stay awake?”

“That’s why I brought you here, Harvard.”

“I’m a fancified alarm clock. Okay, here we go. Wikipedia at its finest.” McAdams paused while he read. “Clara Driscoll was indeed the head designer for Tiffany and worked there for twenty years. She chose the colors and the type of glass and designed some of his most famous lamps. Before her, the designs were more symmetrical and static. Her first design was the Daffodil, but she is also known for the Wisteria, the Dragonfly, and the Peony. She was given her just due when the New York Historical Society gave her an exhibition in 2006 entitled ‘A New Light on Tiffany.’ ”

“Angeline would have been about fourteen at that time,” Decker said. “That’s the age when she became interested in stained glass according to her mom. Maybe she saw the exhibition or read about it.”

“How would Angeline have heard about it if she was in Florida?” McAdams said.

“There’s a museum in Orlando that features lots of Tiffany. Damned if I can think of the name.”

“Morse Museum of American Art.”

“Yes! Exactly!” Decker turned to him. “Did you just look that up?”
