Adrian Monk: Tell me about your boss. Is he a driver?
Jack Monk: He used to be.
Adrian Monk: Does he ever borrow any of these trucks?
Jack Monk: Yeah, all the time. How do you know that?
Adrian Monk: Here's what happened. Ben Glaser borrowed a truck. This truck. And he drove out to see Kenneth Woods. They must've had a fight.
Jack Monk: Makes sense. They hated each other.
Adrian Monk: Ben killed Kenneth, and he hid his body. But he had a problem. There was a record of where he had driven that day.
Jack Monk: Big Brother!
Adrian Monk: Right. And he knew that eventually the cops would check the GPS computer. He had to erase it and quick. He had to put 5,000 more miles on this truck so the box would reset.
Jack Monk: And he sends me out on this wild goose chase. Son of a bitch bastard! Excuse my language.
Adrian Monk: It's okay. I'm a trucker.
Jack Monk: It's unbelievable. You solved it. You did it. You don't even know these people, and you solved the case! Just like when I used to read Sherlock Holmes to you. You'd figure it out by page two.

Adrian Monk: [on the phone, unaware Dennison has picked up Natalie's phone] Natalie. Natalie, here's what happened. This lawyer, Dennison, was having an affair with Judge Garr. She came to his house last night. And at some point they decided to order a pizza. Somehow things turned ugly. Maybe they had a fight. We'll probably never know what it was about. But he killed her. He killed her in that bathroom. But the delivery guy Julio must have seen the attack or heard something. And he tried to help her. He died trying to save her. Natalie, I'm gonna need those cough drops. Not the menthol. You, you, you know the kind. Anyway, Dennison had a problem. The pizzeria knew Julio's route. And Dennison knew that if Julio just disappeared, the cops would focus on him. They'd poke around. They'd ask a lot of questions. So he needed somebody else to be the last person who saw Julio alive. He decided to deliver one more pizza as Julio, to divert attention from himself. You were right, Natalie. Julio didn't deliver that pizza. The man who killed him did. He was smart, but he made two mistakes. Big mistakes. One, that blood you found on the bathroom light switch. If that's the judge's blood, and I think it is, he's going to jail for life. But even without that blood, we can still convict him. Mistake number two, his fingerprints are all over that pizza box he delivered. It's at the recycling dump. I'm sure they can find it if they have to. They just collected it this morning. [phone beeps] Oh, that's my other line, hold on. [switches line]
Natalie: Mr. Monk.
Adrian Monk: Yeah, Natalie, I'll call you back. I'm on the other line.
Natalie: Don't- [switches line] Where was I? Natalie? Natalie? Are you okay?
Reggie Dennison: Say one word to anybody, she's dead. Understand?

Ambrose Monk: Adrian.
Adrian Monk: I'm with you, I'm right here.
Ambrose Monk: Tell me who did this.
Adrian Monk: Ssh. It doesn't matter.
Ambrose Monk: It matters to me. I don't want to die without knowing. Tell me, Adrian.
Adrian Monk: Okay. Here's what happened. His name is Paul Gilstrap. He wanted to kill his wife. He worked in a laboratory where they made tetrachlorodrine. A few days ago, he snuck in there and he stole some of it. Ambrose, I met his wife when I went trick-or-treating with Julie. And she said that she ate a Neptune bar every night before bed. Gilstrap poisoned her candy. But he couldn't poison just one. He wanted to make it look like there was a serial killer on the loose, so he had to poison a lot of other candy bars. Put them back into circulation.
Ambrose Monk: So his wife would just be another victim.
Adrian Monk: That's right.
Ambrose Monk: It's a good plan.
Adrian Monk: But he made a mistake. He got caught trying to put the poison back.
Ambrose Monk: Ruined everything.
Adrian Monk: That's right. It ruined everything. Because now if his wife or anyone else died from tetrachlorodrine, they'd know it was him. So he was desperate. He had to get all of the poisoned candy bars out of circulation. He found them all except for two.
Ambrose Monk: Right.
Adrian Monk: The armored car driver had one. He had already taken a bite. If the driver just dropped dead, Gilstrap knew there'd be an autopsy. So he had to think fast. He grabbed the driver's gun and shot him repeatedly. Who would bother looking for poison in a guy who had been shot five times?
Ambrose Monk: Which left just one candy bar. The one I ate.
Adrian Monk: That's right. He's been trying to get it back all night.
