"I first saw him in a dream ... well, given the nature of it I should probably call it a vision. His name is BOB."

There's something about the name that lets you know it's in capital letters. Cooper looks up at the teenager with the kind of look people get about them when they talk about dark grim things they're passionate about - abuse, neglect, torture. This is important. And he wants to be sure she's following.

"He had a tattoo on his left arm: Fire, walk with me. In this dream, this vision, he promised me he would kill again. I believe he is responsible for the murder and sexual abuse of several children in and around the area he operates in."

But this -

this is the most important.

And he carries on, speaking a little faster, because he's talking about something he's known for all his life - and he has no idea how to fight it.

"It's clear to me that he's not from our dimension, our plane of existance. Call him a spirit, an entity. He kills without inhibition by forcing others to do it for him. He takes hosts into possession and carries out his will through them."

It's with a heavy heart he thinks back on Leland's last moments. The body in his lap and the inside rain ... but, he reminds himself, Leland died knowing who he was.

And Cooper is sure a lot of people don't.
