Quote from Adrian Monk in Mr. Monk and the Big Reward
Adrian Monk: It's a footprint. Somebody was hiding in here. Natalie: Wait, in there? Adrian Monk: That's how they opened the connecting door. Let's grab the detectives, we need an evidence kit. Natalie: Wait, not yet. Adrian Monk: What do you mean, not yet? Natalie: Let's find the diamond, then we'll tell them how we did it. Adrian Monk: Natalie, this is not a game show. This is a felony investi- It's a broken necklace. That's an unusual design. Natalie: Oh, good. We'll try and ID it.
