Adrian Monk: I never realized how strong an electromagnet like that could be. I'm told that one can lift a car. With your background in electronics, building a device like this was child's play. You needed a car battery. You borrowed one from your own Mercedes the night before the murder. You couldn't risk driving one of your own cars, so you took Mr. Bonaduce's keys and borrowed his. And since you had found Noelle Winters's apartment for her, you had copies of all her keys. You knew the apartment was empty because you had sent Ms. Winters to Europe. Now you were where you wanted to be directly below Elliott D'Souza's penthouse, right under his private gym. You knew Elliott worked out every morning. You could hear the weights clanging through the ceiling. You phoned him to make sure he was in position. And then you killed him... Without ever setting foot in the room. That's why the computer disk was erased and the clock was a little off. I knew there was something wrong with that room. Everything was turned around. The pens and the stapler, they were all facing the same way.
