Watched this last night (okay, early this morning), and noticed something. When Charlie and the Chief come back to Charlie's office and discover Inspector Duff on the floor, Charlie does a quick check, says "Strangled", and they treat Duff as if he's dead, although they never actually say so. They certainly don't do anything for him, just leave him there on the floor and don't call an ambulance. But later, Charlie makes a point of calling from the hotel, only to discover that Duff has, indeed, joined his honorable ancestors. Maybe something ended up on the cutting room floor?
