Adrian Monk: Why did he do it?
Captain Stottlemeyer: Why did who do what?
Adrian Monk: Why did Eddie Murdoch kill that girl?
Captain Stottlemeyer: Since when does a creep need a reason?
Adrian Monk: You remember when we were talking to Peter Breen? Murdoch came walking up. Do you remember what he said?
Captain Stottlemeyer: Yeah, he said, "I still have those keys."
Adrian Monk: Peter Breen drives a Ferrari, right?
Captain Stottlemeyer: That's right.
Adrian Monk: What do their key chains look like?
Captain Stottlemeyer: It's a rearing horse. The impression on the coffee table. Those were Breen's keys.
Adrian Monk: You said Murdoch's body's on a slab?
Captain Stottlemeyer: Downstairs.
