“There was blood in the dirt on your shoes,” Jack told him calmly.

“So what?” Quentin looked completely indifferent. “I run every day. I don’t look at the ground when I run. I run through dirt, dog shit, human excrement every day. I could have run through blood. It wasn’t on my hands.” And it wasn’t on his clothes. They had already gone through everything he owned. It was only in the dirt on his shoes. And he could have been telling the truth, although it was unlikely. “You can’t hold me forever. And if that’s all you’ve got, your charges won’t stick. You know that as well as I do. You’ll have to do better than that. You’re full of shit and you know it. The arrest is no good.”

“We’ll see. I wouldn’t count on that,” Jack said with a confidence he didn’t fully feel. They needed some hard evidence to use in the case. They’d had enough to arrest him, although not enough to convict him yet. Hopefully it would come, with a few more lucky breaks. They had good men on their team. Maybe another snitch would turn up, although Quentin didn’t look like a guy who talked. He was much, much smarter than that. And the forensic evidence they were waiting for would nail him.

The questioning went on for several hours, about where he’d been, what he’d done, who he knew, who he met, the women he’d gone out with, the hotels where he’d stayed. It checked out that he’d been in the cities where the women were killed, but so far there was nothing conclusive to tie him to the other girls. They were hanging by a slim thread, but it was good enough for now, and they were counting on the forensic lab to give them more with DNA.

“You’ve got to prove a hell of a lot more than that I ran in the same park.” But the blood and hair would do for now. Even Luke Quentin knew that.

They had never mentioned his passion for snuff films during the entire interrogation.
