The detective enters and talks with Serena and her friends about the murders of Crown and Robbins. They deny knowledge of Crown's murder, frustrating the detective. Needing a witness for the coroner's inquest, he next questions an apprehensive Porgy. Once Porgy admits to knowing Crown, he is ordered to come and identify Crown's body. Sportin' Life tells Porgy that corpses bleed in the presence of their murderers, and the detective will use this to hang Porgy. Porgy refuses to identify the body, but is dragged off anyway. Bess is distraught, and Sportin' Life puts his plan into action. He tells her that Porgy will be locked up for a long time, and points out that he is the only one still here. He offers her happy dust, and though she refuses, he forces it on her. After she takes a whiff, he paints a seductive picture of her life with him in New York ("There's a boat dat's leavin' soon for New York"). She regains her strength and rushes inside, slamming the door on his face, but he leaves a packet of happy dust on her doorstep, and settles down to wait.
