Richard Mason: [on the phone with Lt. Egan] Hello Egan, this is Mason, somebody's been in my house tonight. No nothing has been taken, something's been added, the wedding ring my wife wore when she went away.

Richard Mason: Doctor, I don't believe in ghosts and I don't believe in the supernatural. I don't believe that people live on in life after they left it. But I saw Kathyrn today or someone who looked like her.
Dr. Mark Hamilton: Where?
Richard Mason: Downtown. She passed me on the street, I followed her but couldn't catch her on account of this leg. She disappeared into an empty house.
Dr. Mark Hamilton: How do you know it wasn't Kathryn?
Richard Mason: Oh but it couldn't be.
Dr. Mark Hamilton: Why couldn't it be?
Richard Mason: Well if it was, why didn't she stop when I called her? Why didn't she speak to me?

Richard Mason: Doctor, you've had a lot of experience with mental cases assuming I am a mental case. Ever run across anything like this before?
Dr. Mark Hamilton: Only once, years ago when I was a student in Vienna.
Richard Mason: What was it?
Dr. Mark Hamilton: Man who murdered his wife.

Richard Mason: Mutton? What's he getting mutton for? We're going out to dinner.
Kathryn Mason: We're having mutton tomorrow.
Richard Mason: I don't like mutton.
Kathryn Mason: I don't know why you say such a thing. I've seen you eat it a thousand times.
Richard Mason: A thousand times I told you I don't like it.
Kathryn Mason: Nonsense, it's all your imagination. You can eat anything if you put your mind to it.
Richard Mason: I don't eat with my mind, I eat with my stomach.

Richard Mason: What're you doing here? What've you got to do with all of this?
Dr. Mark Hamilton: I caught the one slip you made. The rose. You said Kathryn was wearing it the last time you saw her.
Richard Mason: She was! It was pinned to her coat.
Dr. Mark Hamilton: I gave her that rose when she stopped at my house. A rose you couldn't have seen when you were supposed to be helpless at home.

Evelyn Turner: Are you ready yet?
Richard Mason: Are we, handsome?
Kathryn Mason: Certainly.

Evelyn Turner: Is your heart in a cage, Professor Holsworth?
Prof. Norman Holsworth: Oh I give it a little birdseed now and then.
Evelyn Turner: That's very strongminded of you, but I'm not quite convinced.
Prof. Norman Holsworth: Neither am I.

Dr. Mark Hamilton: [fishing] Any luck?
Richard Mason: [holds up his fish] Well if you call this luck.
Dr. Mark Hamilton: [laughs] I could use that for bait.
Evelyn Turner: I caught one bigger than that but I didn't like the way he looked at me so I threw him back.

Dr. Mark Hamilton: [on unsolved murder and perfect crime] Laws of chance are overwhelmingly against it, so are the laws of human nature. You see a murderer's whole safety depends upon a complication of lies. If he had no motive, no access, if his alibi is perfect, even if he feels no remorse, think of the strain he endures in knowing one error would be his undoing. That if he is forgetful enough to conflict one of his statements, his act of innocence is unconvincing in any details, if he so much as talks in his sleep.

Dr. Mark Hamilton: I knew everything there was to know, but I didn't know enough to get married.
