Quote from Adrian Monk in Mr. Monk and the Bad Girlfriend
Linda Fusco: They really think that it was a woman? Adrian Monk: Well, they're not sure. Who else had a key to that house? Linda Fusco: Well, let's see, um... The homeowners, obviously, and probably some relatives. Maybe some household help. Anybody here? Your sales staff? Natalie: Yeah, there was a lock box on the front door. Linda Fusco: Uh, yeah, that's true. Any one of the agents could've gotten in, but it could not have been anyone here. We are a family. Adrian Monk: Did Sean have any enemies? Linda Fusco: No. Wait. There was one client. Natalie: A woman? Linda Fusco: Her name was Hubbert. Helen Hubbert. Sean sold her a property last year, and she had been writing him letters. And it was pretty nasty stuff. I think the letters are in his office. Adrian Monk: [notices picture with of Linda with a man holding a hunting gun] Is this a picture of you with your father? Linda Fusco: My grandfather. It's him just before he died.
