Adrian Monk: You have the inventory there?
Natalie: Yes.
Adrian Monk: Were there any matches or cigarette lighters in the room?
Natalie: No.
Adrian Monk: No matches anywhere. That makes no sense. She died on the 15th?
Linda Riggs: Yeah, that's right. Two days before her tenth wedding anniversary. They always did something special. Go on a big trip. Last year they went to Cabo.
Adrian Monk: Not this year. Look, July 17th, "Tenth anniversary". Natalie, nothing's written. Nothing planned. Nothing erased.
Natalie: He knew she wouldn't be around.
Adrian Monk: Linda, I think you're right. I think he killed her.
