Engström tracks down Holt in some rotting wooden buildings at the waterfront and tries to talk with him. Holt suspects that Engström has come to kill him and holds him at gunpoint. He explains how he killed Tanja in a fit of rage when she rejected his advances. Holt tries to flee across a pier, but the rotten floorboards give way and he falls into the water below, striking his head on the way. He drowns as Engström watches. When he rummages through Holt's nearby house, Engström finds Tanja's dress, which Holt had removed before dumping the body. With Holt dead, and this definitive proof that he was the murderer, the case is closed.
