Man in the Attic (1953)
Lily Bonner: It's at night that interesting things happen. What kind of work do you do at night, Mr. Slade?
Slade: I doubt if you'd be interested.
Lily Bonner: Do you just work?
Slade: Sometimes I walk close by the river. The river is like liquid night flowing peacefully out to infinity.
Helen Harley: Did you see that? The little minx wiggled at the Prince of Wales!
Lily Bonner: Is there anything I can do?
Slade: We must each live with ourselves.
Constable #2: [as they are looking for Slade's body in the river] It's too dark, and it's too deep.
Insp. Paul Warwick: Not so dark and not so deep as where he's going.
Slade: Yes, I will tell you. My mother was an actress. She was one of the most angelically beautiful women who ever lived, exquisitely graceful, talented, and captivating. I loved her deeply... deeply. She had the face of heaven and the wretched heart of Jezebel. For every aspect of beauty she possessed, she contained a double portion of evil. I hated her!
Lily Bonner: But I thought you said you loved her?
Slade: I can love the beauty and hate the evil. Didn't you know that, Miss Bonner?
Chief Insp. Melville: [Referring to the police dragnet] Can't get out of this if he's human.
Insp. Paul Warwick: Afraid he isn't human... not and do what he did to that girl.
Slade: [Referring to the death masks of killers in the black museum] You treat them like trophies... like a stuffed elk head mounted over the fireplace.
Insp. Paul Warwick: Yes, a little, but these were more dangerous than an elk. Man unfortunately is the most dangerous of all beasts.
Slade: Man is not beast.
Insp. Paul Warwick: Murderers are beasts.
