- Dr. Parry: The only thing that keeps me from cracking you in the jaw is the almost certain possibility that it would break your neck.
- Mrs. Warren: Forgive me, Steven, I thought it was you. He always waited until you came home, so I thought it was you.

- Helen: [speaking on the telephone] One... eight... nine. Dr. Parry. Come. It's I, Helen.
- [Helen crumples down onto the floor in tears]
- Mrs. Warren: Why won't you do what I tell you to? Why won't you listen to me? Why won't anyone listen to me?
- Mr. Oates: Helen, you look as though you've lost your best friend. You got nothing to worry about. If anyone tried their funny business on you, I'd soon sock 'em in the jaw. Look at it this way, Helen - murder's like a million-dollar lottery. Sure it is - listen. You pick up the newspaper, you see someone's picture who's won a million dollars. Pick up another paper, you see someone's picture who's been murdered. It's never me, and it's never you. It's always somebody else, isn't it?
