Decker made a face, although Marge couldn’t see it.

“Garth’s river-rafting buddy?”

“That’s the one. Otis’s mailbox is still full, so it makes sense that he might be in the middle of nowhere, but Crystal has her doubts.”

“What do you mean?”

“One of the other buddies, Greg Reyburn, told her that the guys were also headed to Reno for a little R and R.” She recapped their interview. “It seems Garth likes his games of chance and all the vice associated forthwith.”

“Interesting.” Decker was sprawled out on his bed, talking on the extension on his nightstand. “When are the boys due to back in town?”

“According to Garth’s phone message, it should be in a few days,” Marge said. “Adrianna was apparently angry when she found out about Garth’s detour. Maybe she was thinking about finally calling it quits.”

“If Adrianna wanted to break up with Garth, why call Aaron and not Garth?”

“Maybe she knew that if she called Garth’s number, he wouldn’t answer.”

“Or maybe she was having a fling with Aaron.”

“Cheating seems to be a pastime with the two of them. Any indication in her diary of something between Adrianna and Aaron?”

“Not so far, but I’ve only skimmed it. Her last entry was dated five days ago and all it said was that Garth was going out of town on a river-rafting trip. Reading the entire diary carefully is going to take time.” Decker looked at the nightstand clock. It was a little after midnight and Donatti had yet to even call. “I might have a lot of that. I’m still waiting for Chris Donatti to pick up his son.”

“Is he late?”

“Not yet, but until he gets here, I’m skeptical. Anyway, most of what I’ve read so far buttresses what Crystal told you about Adrianna and Garth—that her sex life was lacking and she wondered a few times if he was getting it elsewhere.”

“Was she angry?”

Decker paused. “More disillusioned than anything else.”

“Any candidates for Garth’s fling in her diary?”

“None so far, but I’ve been thinking about Mandy Kowalski. Didn’t you tell me that Garth came on to her?”

“That’s what she told us. She said that Garth was a player and she’s probably right about that.”

Decker said, “If Garth was a player, why did Mandy set him up with her friend, Adrianna?”

“No idea.”

“Ask her about it. And find out where she was the morning of the murder.”

“She was working.”

“Get a time line on her. Maybe there’re some unexplained absences.”
