Quote from Natalie in Happy Birthday, Mr. Monk
Kurt Pressman: I gather from the lieutenant that you don't think Richard died of natural causes. Natalie: We can't talk about the case, you understand. Kurt Pressman: You mentioned another case, a janitor you feel might be connected? Adrian Monk: It's possible. It's a work in progress. Natalie: Yeah, Mr. Monk always says it's a work in progress just before he figures it all out. Kurt Pressman: Really?
