Black Limelight

Mary Charrington:
You've been very careful, but you made one mistake. It'll be the first time that anyone has suggested you as the murderer. You'll be watched, you'll be questioned, you'll be followed, you'll give yourself away, and they'll get you.

Lawrence Crawford:
I killed her, did I? Accusing me, are you? Why don't you run away Mary? Move if you can, but you don't move Mary. Why?

Mary Charrington:
Because...

Lawrence Crawford:
Because you know I'm not the killer.

Mary Charrington:
Yes!

Lawrence Crawford:
That's where you're wrong. I am the Dorset murderer. I killed Lily James, and all the others, and now I am going to kill you!
