Quote from Adrian Monk in Mr. Monk Can't See a Thing
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.
