Dr. Jo Hardy: [John enters his lab still dressed in his hat and overcoat, turns on the lights and clearly intoxicated, weaves his way to a small file cabinet and loudly opens and closes several drawers until he finds the file for which he is looking. Jo enters, wrapping her dressing gown around her] Where have you been?
Prof. John Hardy: With his lordship at the club.
Dr. Jo Hardy: It's 3 o'clock in the morning! What on earth were you doing?
Prof. John Hardy: Mmph. Talking about the case.
Dr. Jo Hardy: But you weren't even called!
[helps John off with his overcoat]
Prof. John Hardy: No, I was merely an interested spectator.
Dr. Jo Hardy: John, it's over. He's guilty! He's confessed!
Prof. John Hardy: Yes. Why did he confess? He was so safe.
Dr. Jo Hardy: From, the police, yes! But not from himself.
Prof. John Hardy: Huh, ho. Pangs of conscience, you mean. No!
[shaking his head]
Dr. Jo Hardy: Jo: Yes, I do.
Prof. John Hardy: I don't believe that and neither did the judge. I know people are always confessing to crimes they haven't committed. Ahh, they're exhibitionists but not that young man. No. He's very calculating. He must have had something to gain.
Dr. Jo Hardy: Darling, he did it!
Prof. John Hardy: No!
Dr. Jo Hardy: Now why are you so sure?
Prof. John Hardy: Because he admitted to the judge something he hadn't done. He said he'd had sexual intercourse with a woman when he hadn't. Quite plain he was guessing and he guessed wrong.
Dr. Jo Hardy: Listen, John. If you were innocent would you have confessed to murder?
Prof. John Hardy: No, I don't seek that kind of notoriety.
Dr. Jo Hardy: Well, if you were guilty, would you?
Prof. John Hardy: No! As a forensic expert, I'd cover up my traces.
Dr. Jo Hardy: Good! Then come to bed
