As I stare down at my notes, something prods at the back of my brain. Some thought or theory that hadn’t yet congealed. I pull out the crime scene photos. I look at the bloody handprint on the jamb. The print in the living room. The instruments in the barn. Finally, I come to a single photograph of the three scuff marks on the dusty floor. I look at my notes and one line I’d written stands out like neon. Her lover liked to take photos. I stare at the photo, and I think: tripod.

“What’s up?”

I glance up to see Tomasetti standing at the door to my office. “I think he may have photographed or filmed the murders.”

“What?” He’s already crossing to my desk. “How do you know?”

I show him the photo of the scuff marks. “No one could figure out what made these marks. Mary wrote in her diary that her lover was into photography. I think the marks are from a tripod.”

Intensity tightens his features as he stares down at the photo. “Maybe that’s why the girls were tortured.”

“Jesus. A snuff film.” The words feel like rancid grease pouring from my mouth. They make me sick to my stomach. I flip over the photo of the instruments. “He left these behind.”

He stares at the photo, his expression unreadable. But his eyes are a little out of focus when he raises his gaze to mine, and I know this has brought back his own past, reminded him of the murders of his wife and children. My initial instinct is to reach out to him, but I don’t. I know him well enough to realize that while he might need sympathy, it’s the last thing he wants.

“I’ve got a contact down in Quantico,” he says after a moment. “I’ll give him a call, tell him to put his ear to the ground.”

I nod.

He gives me a grim look. “The FBI has never been able to authenticate a snuff film, Kate. Never. They’re an urban legend. A Hollywood invention.”
