Adrian Monk: Something's off here.
Natalie: What is it?
Adrian Monk: Glass shards on the inside. When that case was shattered, this case was open. I think they took this weapon, used it, and put it back and relocked the case.
Natalie: What does that tell us?
Adrian Monk: A lot. It means it was an inside job. And they didn't want us to know it was an inside job.
Natalie: [giggles] Ka-ching!
Adrian Monk: What does that mean?
Natalie: It means we're gonna be rich. Ka-ching.
