Adrian Monk: Here's what happened. Your husband never abducted you. No one abducted you. It was a setup from the very beginning. You did spend three days in that cabin, but you weren't a prisoner. You were hiding out. You were waiting. You chained yourself up so the bruises would be real. And you starved yourself.
You were an actress, preparing for the biggest performance of your life. Then, last night, you went back to your house. You brought a rug from the cabin and you put it down to the floor. Then, you waited in the shadows. You killed him there, then dragged his body back to the cabin. It was show time. To the world, you were a woman who had escaped from her sadistic husband. You were a hero. A very wealthy hero.
Sally Larkin: Well, that's a very nice little story, Detective Monk.
Adrian Monk: It's more than a story. I can prove that you didn't spend three days in that cabin, chained to the floorboards. You made one mistake. While you were missing, we went to your house to question your husband. The captain was chewing some gum. He had some trouble. He ended up spitting it out. Last night, after the murder, you accidentally stepped on the same piece of gum. [removes gum from mouth] This piece of gum. The one that was stuck to your shoe.
Sally Larkin: You can't prove that's the same piece of gum. Gum is gum.
Adrian Monk: Not this gum. This is Disher-Mint gum. Diet blueberry. It's homemade. It was on your shoe.
Sally Larkin: You've been chewing that piece of gum for five hours?
Adrian Monk: No. I've been chewing this piece of gum for five and a... Half. Oh, my God. Chewing this gum for five and a half hours! [throws gum on the ground]
