“Minneapolis is a big city. That doesn’t mean anything.”

“Fifteen years ago, you were fired from your job as a custodian at a school in Superior,” Maggie continued. “I talked to the woman who was the principal back then. She said there were accusations that you had been going into the locker room at inappropriate times to watch the girls.”

“Oh, come on, like I’d be the first janitor who liked to sneak a peek now and then,” Finn said. “I’m not saying I did, but what’s the big deal? The teachers all do it, too. It doesn’t mean anything.”

“We’re searching your house right now,” Maggie told him. “There are officers tearing your place apart. What are they going to find, Finn? Photos? Maps? We’re going over your car with a toothbrush, too. We’ll find something that ties you to the girls you’ve been stalking.”

Finn’s bald head glistened with sweat under the hot light. “I think I should go. I thought you wanted to talk about Laura. I’m not saying anything else about stalking or peeping or whatever the hell you think I did.”

“You can go if you want,” Stride said. “But you brought it up, so let’s talk about Laura. She had a tattoo almost identical to the one that Mary Biggs had. Did Mary’s tattoo remind you of Laura? Is that why you focused on her?”

“I’m not saying anything.”

“You told me you saw Laura and Cindy in the woods that night by accident. Then we find out about Mary Biggs and all these blond girls with someone panting outside their bedroom window. You know what I think, Finn? I think you were watching Laura. I think you were stalking her. Sending her threats. I think you followed her to the park that night.”

“I didn’t stalk her,” Finn replied. “I never sent her any letters.”

“There’s something else,” Stride continued. “We never released this to the media. Someone masturbated at the crime scene where Laura was beaten to death. I guess the guy was so turned on by what he had done he had to jerk off. We still have the semen, Finn. What happens next is we get a court order to sample your DNA and we match it against the semen we found at the scene. I think we’re going to get a match, Finn. I think you were at the murder scene that night.”

“I told you, I don’t remember,” Finn said.

“Then let us help your memory. Give us a DNA sample right now. Let us run the test. Don’t you want to know the truth?”

Finn looked at them, horrified. “No.”

“You told me how hard it is to live your life not knowing if you killed someone. Maybe it will unlock your memory if you find out you were really there.” Stride paused and said, “Or maybe you remember already, Finn. Maybe you know what happened that night.”

“I can’t tell you anything. It’s gone.”

Stride shook his head. “It’s not gone. It’s still inside your head. You say you saw someone attacking Laura. Trying to rape her. Are you sure it wasn’t you?”
