Tom Donovan: What's going on? Is there any news?
Captain Stottlemeyer: You remember Adrian Monk? He just spent five days with Ralph Roberts at the sibling ranch.
Tom Donovan: Oh, good. What did you learn? Two things. People don't like being stopped at the airport, and you're hiding something. You killed her. Didn't you?
Susan Donovan: John? Is everything all right?
Tom Donovan: I'm not sure. My wife. Susan, these men are with the police. They just accused me of murdering that poor girl.
Susan Donovan: What? You must be joking. Everyone knows who killed her. It was that whack-job. That cult leader.
Adrian Monk: I thought so too, ma'am. We all did, but that whack-job was definitely 140 miles away in his cabin on the night of the murder.
Captain Stottlemeyer: We know that Father was there, because he wasn't alone.
Adrian Monk: I remembered something. One of the cult kids, Brother Zack, said he was sitting outside the cabin all night. He said he heard a microwave beeping from inside.
Susan Donovan: What the hell are you talking about?
Adrian Monk: I was in that cabin. There are a couple of lamps. There's a hot plate. There is no microwave oven.
Natalie: What the boy heard was a beeper.
Adrian Monk: It belonged to a doctor, making a house call. Father has trouble bending down. And that explains the plastic cap. It was from a syringe.
Lieutenant Disher: Father has a bad back.
Adrian Monk: It's a big secret, of course. He's supposed to be the eternal one, who never gets sick. He even built a secret door in the wall so that doctors could go in and out without being noticed. I remember seeing a ridge in a dirt behind his cabin.
Captain Stottlemeyer: We found the doctor. He's an osteopathic surgeon named Wesserman.
Lieutenant Disher: He goes to the ranch once a week to give Father a cortisone shot.
Captain Stottlemeyer: See, Father has a beautiful alibi that he can't tell anybody.
Susan Donovan: Okay, so maybe it isn't this man, this- This Father person. That doesn't mean that Tom was involved.
Captain Stottlemeyer: Your husband swore that he saw Father at that rest stop. He picked Father out of a lineup twice. Now, if Father wasn't there, that means your Husband is lying and I'd like to know why.
Susan Donovan: Okay, this is ludicrous. My husband is a hero. He tried to save that woman. He drove her to the hospital. Look, look. This just came in the mail. I can prove it. It's a traffic ticket. He must have run a red light. They have one of those automatic cameras. That's him and that's the girl. That proves it, right?
Adrian Monk: Yes, ma'am. I'm afraid it does. Where's the car?
