As he begins to comprehend that the relationship between Marian and Ted is not to do with "business", as they have claimed, Leo naively believes that Marian's engagement ought to bring the correspondence between her and Ted to an end. Feeling increasingly uncomfortable about the general atmosphere of deception and risk, Leo tries to end his role as go-between but comes under great psychological pressure and is forced to continue. Ultimately, his unwilling involvement has disastrous consequences when Marian's mother makes him accompany her as she tracks the lovers down to their hiding place and discovers them having sex. The trauma that results leads directly to Ted's suicide and Leo's nervous collapse.
