Quote from Adrian Monk in Mr. Monk and the Bad Girlfriend
Natalie: Was he leaving? Linda Fusco: Well, it's no secret that he was starting his own company. That happens all the time. Um, yes. Here it is. Helen Hubbert. I met her at a closing once. She didn't seem dangerous. Maybe a little tightly wound, but I guess you can never tell. Adrian Monk: No. You can't.
