Adrian Monk: Here's what happened. Three weeks ago, Magneri went in for a checkup. You were the lab tech
on duty. You must have noticed something on his X-rays. Something serious. Something that could kill him.
Natalie: It was the ultimate piece of inside information.
Captain Stottlemeyer: Literally inside.
Adrian Monk: Peter Magneri is Magneri Computers. You knew if anything happened to him, the stock would plummet. All you had to do was switch X-rays and put a different label on it. Magneri got a clean bill of health. Nobody knew how sick he really was, not him, not even his doctor. But you knew. You quit your job and started selling short, betting against the company. When Magneri died and the stock crashed, you'd make a small fortune. At some point, Vickie found out. Maybe you were looking for a partner. Maybe you were just bragging. But Vickie wasn't like you. She couldn't just sit back and do nothing and wait for another human being to die. She tried to warn Magneri. You knew you had to stop her by any means necessary. That night, Vickie told Magneri it was a matter of life or death. She was talking about him. His life or death.
Captain Stottlemeyer: You chased her down. You killed her on the beach and you took back the X-ray.
Arlene Boras: That's insane. You don't have any-
Natalie: Proof? Mr. Monk found this. It was hidden behind your toilet.
Adrian Monk: Behind your toilet!
