Captain Stottlemeyer: Registration sheets are all gone.
Lieutenant Disher: Monk, do you have a cell phone number?
Adrian Monk: No.
Lieutenant Disher: Do you know where they stayed?
Adrian Monk: Some hotel.
Captain Stottlemeyer: There are over 200 hotels in this city, Monk. It'll take us over five hours to check them all.
Adrian Monk: Hold on. Hold on. [tenses his back]
Lieutenant Disher: What's he doing?
Captain Stottlemeyer: I don't know. What are you doing?
Adrian Monk: The hotel where they're staying. It was on the registration form.
Captain Stottlemeyer: Yeah, so?
Adrian Monk: When Dianne signed it, we were standing in line. She wrote... She wrote on my back.
Lieutenant Disher: Can he do that?
Natalie: That's how he met Trudy. It's his superpower.
