Columbo: A letter addressed to the Department of Immigration and Nationalization that identifies you as a war criminal. Means, opportunity, and motive. It's enough to convict for first-degree murder.
Santini: It's impossible. It's a trick and not a very good one.
Columbo: A trick? No, that's the letter.
Santini: Oh no, Lieutenant. No, you see, this letter was burned. (letter goes up in flames) So much for your letter.
Columbo: (dramatically pulls another letter from his pocket) There's the letter! I hope you were watching carefully. That's my best trick. Of course, I don't have your style but I get pretty good results.
