Adrian Monk: Who else has access to this courtyard?
Dr. Kroger: Just me. And Francis Merrigan. Do you see anything?
Adrian Monk: I see a lot of powdered milk. Eight or nine cartons. He was carrying a carton with him yesterday too.
Dr. Kroger: So?
Adrian Monk: So I don't see a coffeemaker, do you?
Dr. Kroger: No.
Adrian Monk: Powered milk is made from lactose. Drug dealers use it to cut heroin.
Dr. Kroger: You think that Francis Merrigan is dealing drugs?
Adrian Monk: And I think he murdered your cleaning lady.
Dr. Kroger: Adrian, I don't think you should talk about Francis Merrigan anymore.
Adrian Monk: Why not?
