Strangers On A Train

Bruno relaxes in a beach chair while Gerard hunts for clues. Bruno has begun to receive his father's money. Bruno excises Guy's name from a pocket book so that Gerard does not connect them. Gerard finds the gloves, and correctly determines Guy's escape route. Gerard knows that Guy put the milk crate next to the wall and broke the back-door lock. Elsie has been in bed since Saturday night. Bruno reflects that neither the butler, Herbert, nor his mother will protect him from Gerard's enquiry. Bruno is shocked when he overhears his mother agree to report on him to Gerard. 

Bruno argues drunkenly with his mother about Gerard in a restaurant. Bruno spots Gerard observing them and storms out, despite his mother's protests that he is hallucinating. Bruno has an impulse to call Guy but awakes with no memory of having done so. He wonders whether Gerard could have traced the call. Bruno gets the shakes and tries to soothe himself with more alcohol.

Guy feels secure, surrounded by work and his meticulously-cleaned house, which assuage his guilt. He can only sleep two or three hours a night, but has disposed of all evidence of the murder, except the revolver. Guy thinks that he will kill Bruno if he contacts Guy again, then recollects on his belief in God. Guy has not told Anne about the hospital he is designing. Contemplating the dual nature of things, Guy wonders whether he has gone mad. He has a recurrent nightmare about trying unsuccessfully to kill a stranger, who is Bruno. He awakens and cries, thinking of Anne. Dawn comes, and Guy returns to work.

Guy is driving with the Faulkners. He breaks hard, and the car stops just short of a child. Guy had swerved towards the little boy, horrifying the Faulkners. Guy has been accident prone over the past few weeks. Anne drives them to the couple's new home in Alton. Guy is out of sorts and feels that this must be obvious to everyone. Anne and her family express concern for Guy. He kisses Anne but is conscious of an "enormous" change in himself.
