chunk: Charlie is panicked and tries to stay away from Harriet without letting her know what he knows, but the hotel staff force him into the honeymoon suite for their first night together. Charlie finds himself alone and discovers a "Dear Jane" letter, purportedly written by him, explaining his absence to Harriet. Suddenly, Rose appears wielding an ax. Rose tells Charlie he was not supposed to find the letter, and reveals herself as the Mrs. X killer - she feels that Harriet's husbands are taking her sister from her, and so killed them on their honeymoon night and leading Harriet to believe that each husband simply left her. Charlie begins a game of cat-and-mouse to stay away from Rose while waiting for the police to arrive.
