Captain Stottlemeyer: [on the phone with Monk] You were right about the pigeon. The bird was poisoned. I had them go back and do a tox scan on the armored car driver. Turns out he had been poisoned too before he was shot. The poison was called-
Lieutenant Disher: Tetrachlorodrine.
Captain Stottlemeyer: Tetrachlorodrine, very deadly.
Lieutenant Disher: Stronger than arsenic.
Captain Stottlemeyer: It's stronger than arsenic. It came straight from the lab. It hadn't even been diluted yet. And get this. We just talked to the plant manager here. Turns out some of the stuff had been stolen. They didn't realize it until today because they caught the guy trying to put it back.
Adrian Monk: Wait. Wait. He was putting it back?
Captain Stottlemeyer: Yeah, they had to let him go. He denied anything and they didn't have any evidence. The guy's name is...
Lieutenant Disher: Gilstrap.
Captain Stottlemeyer: Gilstrap. He worked here part time fixing computers.
Adrian Monk: Gilstrap? Paul Gilstrap?
