- Brian Mullen: And, what if you could prove that he was at that movie the time the girl was killed?
- Detective Lt. C.A. Bruce: To Tell you the the truth Mr Mullen, I've rarely met a murderer who wasn't at a movie at the time of the murder.
- Brian Mullen: [Stopping Peter from leaving Lottie's party] Oh no, you don't. You're not going to leave me in there all by myself.
- Peter Denver: Would you like to go out on the terrace?
- Brian Mullen: Good heavens! You're not thinking of jumping, are you?
- Peter Denver: Where on earth did you and Lottie meet all these people?
- Brian Mullen: Who's met 'em?
- Brian Mullen: [to the waiter.] Bring Mr. Denver a drink, will you?
- Party waiter: Yes, sir
- Brian Mullen: Yours is the first face I've recognized here tonight.
