Captain Stottlemeyer: Still no murder weapon. Doc says knitting needle. What do you think? He was tossing the place, she walked in?
Adrian Monk: I don't think so. Look at the drawers. They were pulled out and flipped over, but everything's just piled up. He didn't really rifle through it. He was here for her.
Lieutenant Disher: Captain. Check this out. Found it in her closet. Four grand, maybe more. In 20s and 50s.
Natalie: Jeez, I should've gone to nursing school.
Adrian Monk: 1967. 1966. These are 40 years old. Some of the serial numbers are sequential.
Captain Stottlemeyer: I'll call Treasury. Maybe they can trace 'em. Wanna come?
Adrian Monk: I can't. I should go home. See if it's still there.
