"Why does he always pose them like this?" Harris said, walking carefully around the pair of corpses.

"For the same reason they're always killed from behind" I said, "stabbed in the lower back. Leaves the face and hands undamaged."

Agent Harris looked up from the crime scene, staring at me from the other side of the circle. "Huh, I didn't notice that bit" He said, taking another sip of his coffee.

The forensic photographer stood nearby, taking pictures of the bodies from every angle. "Hey kid" I said, getting his attention.

"I'm 24, I'm not a-" the kid began.

I grunted dismissively, in the way only a decades long smoker like I could produce. "Do you have access to the other crime scene photos from this case?" I asked.

"Um, yeah, back in the car" the kid said. "Why?"

I gave the kid the silence that question deserved, staring him down with an iron gaze until he took the hint. "I'll, uh, go get them, sir." He stammered, before leaving the scene.

"What..." Agent Harris began, but I cut him off with a wave. We waited in silence until the kid returned, handing me a thick manilla envelope. I took it without comment, and began sorting the other victim's photos by date. I held the photos by the top edge, and began to slowly flip through them. All of the victims were posed in the same shape... although there were subtle differences, only a few inches here or there...

"My God", Agent Harris gasped as he watched over my shoulder. "Its..."

"A flipbook" I finished for him. "Sick bastard's using corpses as characters in a flipbook".
