“What?” he yelled from the other room.

“You need to come here now,” Marge said. “We’ve found her dark side.”

He came bolting in as Marge spread the photographs on top of the bed. In several snapshots, Mandy was on all fours, garbed in black fishnets, garter belt, and a leather bustier. A spiked dog collar was pulled against her neck by a taut leash. The man who was restraining her was masked and shirtless, with ripped muscles and a six-pack. Even though his facial features were obscured, he had plenty of identifying tattoos. Didn’t look like Aaron Otis’s ink work, but she’d definitely have a look at the young man’s arms again.

Both she and Oliver had seen lots of pictures of this sort of thing. Mostly the photos looked like silly sex games. Not this time. The pose was menacing enough, but there was something about Mandy’s expression that told her it wasn’t a joke. The cat-o’-nine-tails that the man was gripping in his right hand sealed the deal.

“Quick question,” Marge said.

“Tell me.”

“The pictures look pretty well focused, no?” Marge said.

“Yeah, you can make out detail. Why?”

“They don’t look like they were shot with a timed camera on a tripod. So my question is—who took the pictures?”

A KNOCK ON the interview-room door, then Wanda Bontemps came inside. “Sergeant Dunn on line three. She says it’s important.”

Decker nodded and stood up. “Excuse me for a moment, Aaron. Would you like something to drink? Some coffee or soda?”

“Water would be great.”

“I’ll get it for him,” Wanda volunteered.

Decker closed the door behind him and took the call in his office. “What’s up?”

“Did Aaron Otis ever come in?”

“I was just finishing up with him. What’s up?”

“Can you take some snapshots of his arms?” Marge explained why. “I don’t think it’s him, but I’d like to make sure.”

“I can hold him here for another twenty minutes or so. If you bring in the photographs, maybe he can identify the tattoos.”

“Maybe. Or maybe he was there, Rabbi. The photographs looked staged and that means someone snapped the poses. If Garth and Aaron were swapping girls, why not Mandy?”

“Good point. Aaron just confessed to me that Garth likes to do it from the back because he likes to be in control.”

Marge squatted down and slid the bottom drawer back into the shelf. “I would say with a hundred percent certainty that the guy in the photograph likes to be in control.”

“Get here as soon as you can with those pictures.”

“And what’s our justification for taking personal stuff from Mandy’s apartment?”

“We have two brutal homicides and we can’t find Mandy Kowalski anywhere. Then we see these pictures, so now we’re really worried about Mandy’s safety. It’s imminent danger. And that’s no lie.”
