Agent Thorpe: What the hell's going on? Who told you to stop?
Adrian Monk: I did.
Agent Thorpe: What are you doing? I told you before. She doesn't matter.
Adrian Monk: Actually, Agent Thorpe She not only matters, she is the key to this whole case. Your so-called Six-Way Killer killed her first.
Natalie: The other kid, the street musician, was just a diversion.
Adrian Monk: It's true. Captain, the same guy killed both. You found a liquor bottle in the killer's car. Remember, there was a cognac stain on her sleeve.
Lieutenant Disher: Monk, do you know who did it?
Medical Examiner: Oh, she'll tell us if it's not too late. We've already wasted a day and a half.
Adrian Monk: It was the deadline. 36 hours. It seemed so arbitrary, didn't it? I mean, when you really stopped and thought about it. Then Natalie reminded me how hard everybody was working on the Six-Way Killer case.
And I wondered, "Who would benefit from that?" And there's only one answer. The man who killed this woman.
