Ward Fowler: You think she was murdered, don't you?
Columbo: I, I beg your pardon, sir?
Fowler: You heard me.
Columbo: Yes sir, I did. Uh, I mean, yes, I do think it was a premeditated killing, sir. I mean I think the robbery was staged to cover up the murder. Um, (acts incredulous) How did you know, sir?
Fowler: Why else would you be here?
Columbo: It could be just a routine check, sir.
Fowler: No, Lieutenant. They don't send a police detective stumbling around, asking silly, fake, innocent questions on a routine check. I know that from my show.
Columbo: Silly, fake, innocent questions, like what, sir?
