“What‘s the ruckus in the lounge?” she asked. Her eyes focused on Carl. “Is that a real monkey?”

“Yep, it‘s a real monkey,” I told her. “And this big guy is Diesel. He‘d like to talk to you about your grandson.”

“Martin? I don‘t know what to say about him. I haven‘t seen him since Christmas. I know he‘s accused of stealing something where he worked, but it‘s hard to believe. He‘s such a nice young man.”

“I need to find him,” Diesel said. “Do you have any idea where he might be staying?”

“He has a house in Trenton. Other than that, I don‘t know. There‘s not a lot of family left. His mother and father were killed in a car wreck five years ago. He doesn‘t have any brothers or sisters. The rest of the family is in Wisconsin. He was never close to any of them.”

“Friends?” Diesel asked.

“He never mentioned any. It was always hard for him, being so smart. He didn‘t go through school with kids his own age. And then he had that whole Star Trek thing where he dressed up like Mr. Spock. I told my daughter to get him help, but she said it was just a phase. And when he took the job at the research center, he was working on something secret that he couldn‘t talk about. He was real excited about it. He worked all the time on it. Weekends and nights. I thought he should be going out with girls, making some friends, but he said everyone he met was boring.”

“Did he ever mention someone named Wulf?” Diesel asked.

“No,” she said. “I would have remembered.”

Diesel gave Lydia a business card. “I‘d appreciate a call if you hear from Martin.”

I looked over at the card. It said Diesel, and below that was a phone number.

“Very professional,” I told him.
