Sam listens to this confession and then tells Brigid that he's turning her over to the police for Miles' murder. She is incredulous; Sam can't turn her in- he loves her and he has to help her. Sam says that maybe he does love her, but he's still going to turn her in. Brigid pleads that she loves him, but Sam isn't going to play the fool for her. He tells her that, when your partner is killed, it's your duty to do something about it. He remarks that she'll probably get a twenty year prison term, but that if they hang her, he'll always remember her. Tom Polhaus and Lt. Dundy show up and Sam gives Brigid to them, explaining that she murdered Miles. He also gives them the thousand dollars which he got from Gutman, to Dundy's disappointment; Cairo had told them about it, and he was hoping that Spade would incriminate himself. Gutman couldn't tell them because -Polhaus tells Sam- when they got to the Alexandria, he had just been shot and killed by Wilmer.
Later, at his office, Sam tells Effie what happened and she is upset that he turned Brigid in. As they are talking, the doorbell rings and Effie goes to answer it. She returns to tell Sam that Iva is there. Gloomily he tells Effie to let her in.
