Quote from Adrian Monk in Mr. Monk and the Genius
Captain Stottlemeyer: What do you got? Lieutenant Disher: You're not going to like it. The M.E. said natural causes, severe cardiac arrest. Adrian Monk: What? Lieutenant Disher: He's already released the body. Adrian Monk: What- What about a complete toxicology workup? Lieutenant Disher: He won't do it, Monk. Not without probable cause. Natalie: But she was 42 years old. Adrian Monk: What about the water? The tap water in the bathroom? Lieutenant Disher: Checked. Natalie: Well, how 'bout her lipstick? Lieutenant Disher: We checked that too. I mean, toothpaste, even her eyedrops, everything in the house, It's all clean. Adrian Monk: He killed her. He poisoned her. But how?
