Captain Stottlemeyer: Monk! Where's Grayson?
Sharona: He's still inside. Monk doesn't think he did it.
Captain Stottlemeyer: Oh, really? Well, this should interest you. Grayson bought a bunch of knives online a year ago that match the murder weapon.
Adrian Monk: A million people buy knives online. And we know Grayson collects weapons.
Captain Stottlemeyer: What do you got? "Something's wrong, Captain. It doesn't make any sense, Captain." Huh? You got nothin', Monk. Grayson is the guy. If I had a farm, I'd bet it.
