Oh, hello. I'm Rod Blake, chief investigator for the Nevada state troopers. I've just been re-reading somebody else's mail - line of duty, of course. Funny thing about a letter... it can bring good news or bad; make a man laugh or cry; reassure him or panic him. A three-cent stamp - probably the most powerful tool you can buy at that price. I'll be back in a moment to show you how it was used in a case we call, "The Cash Out".
