Quote from Dick in Dial M for Dick
Inspector Macaffery: [Enters] Everybody stay exactly where you are. Good evening, ladies and gentlemen, please take your seats. I am Inspector Macaffery from Scotland Yard.
Tommy: He got here quick.
Inspector Macaffery: No one is to leave the premises. Until further investigation, everyone is considered a suspect.
Dick: Everyone? Sh-sh-surely you don't mean everyone?
Inspector Macaffery: Given the right circumstances, anyone is capable of murder.
Dick: But not everyone.
Inspector Macaffery: Yes, everyone.
Dick: But not anyone.
Inspector Macaffery: Yes.
