Quote from Natalie in Mr. Monk and the Big Reward
Natalie: What is up with those three detectives? Do you think we lost them? Adrian Monk: Oh, Natalie, they are not detectives. They're rent-a-cops. They're hired guns. They are mercenaries. In other words, they're us. This whole thing is about greed. Natalie: You know how you always say you'll thank me later? You'll thank me later.
