Quote from Natalie in Mr. Monk and the Red Herring
Natalie: Captain, why are they doing this? What do they want from me? Captain Stottlemeyer: Who's "they"? Lieutenant Disher: There was, uh, another intruder two days ago. Natalie: On Tuesday, a man came to my house. He said he was here to check my water meter. But he didn't go downstairs. I, I caught him over there just looking around. But when he saw me, he ran out the back door. Lieutenant Disher: We called Water and Power, but there's no record. Captain Stottlemeyer: And this was a different guy? Natalie: Yeah. Captain Stottlemeyer: You're sure about that? Natalie: Yeah.
