Sheriff Fletcher: Adrian, let's try this again. When they found you, you were carrying this bag. You wouldn't let go of it. I think it's important. I'm looking at batteries, engine lubricant, eye glass wipes.
Adrian Monk: I know what happened.
Sheriff Fletcher: You mean about the UFO or about Marge's murder?
Adrian Monk: Both. It's all connected. The eye glass wipes, they're Kyle Larkin's. He killed his sister. For the money, of course. He put her in a hiking outfit and dumped her body in the desert. It would look like an accident. Like she was out hiking, lost her footing, and fell. As soon as anybody found the body, he'd be rich. He went home and waited for the call that his sister's body had been discovered. But something was wrong. The call never came. He realized the coyotes must've dragged it away. Without the body, he couldn't prove she was dead. He had to find it, but how? You said Kyle owned a store. I could make out some of the lettering on the door of his van. It said "Models and Hobbies."
Sheriff Fletcher: That's right. He sold kits for model trains.
Adrian Monk: And airplanes.
Sheriff Fletcher: And airplanes.
Adrian Monk: More. [drinks] He needed somebody else to find that body. Anybody else. So he build a UFO. It was a just a remote control model. Then he made what looked like a landing site. He knew somebody would see it and the news would spread. He knew the Internet people would come. They believe anything.
Dr. Garcia: So basically he was putting together a search party.
Natalie: He just needed people out there looking around the desert. He knew someone would eventually find his sister.
Sheriff Fletcher: It has been an honor to watch you guys work. Mr. Monk, Ms. Teeger, I am going to be forever grateful that your vehicle broke down in my neck of the woods. But if you will excuse me, I have a suspect I need to go arrest.
Sheriff Fletcher: Your fan club's here. They're gonna be mighty disappointed that none of this was real.
Adrian Monk: I'll tell them. Let me talk to them. I'll let them down easy. Okay, Natalie, watch this.
