Curtis interviews suspects, including Vayne, who confesses—that his name is really Henry T. Herrick. The lights go out; a white face appears and disappears. A distraught Vayne/Herrick cries out: It is the death mask of his son, Tom (the unnamed youth in Jenny's story). He wore it when he knocked out Esther and tried to kill Jenny. Herrick dies of a heart attack. “Wait, I remember now!” Esther calls. The lights go out; she is stabbed with a dart that misses her neck. At 5 a.m., she is asleep, locked in her room. Faith is looking after her. Curtis is frustrated: If Esther had been killed, Faith would be the obvious suspect. Carter has disappeared. Exploring outside, Curtis and Harris discover a tunnel door at the cliff. Inside, they find Carter's body and the death mask. Back in the house, Curtis stands where Jenny's murderer stood and mimes the dart throw, knocking the wall with his hand. In the wall, he finds a chip from a ruby ring. Curtis realizes that Faith Andes mistook Jenny for Esther. Using the tunnel, Faith has taken Esther out to the cliff edge. Forestalled, she calmly confesses before Esther, Frank, Curtis and Harris. As the police plane flies overhead, Curtis, face to face with Faith, pushes a stone over the edge with his toe. “Thank you,” she says, and follows it. Esther and Frank cling to each other as Curtis and Harris walk away.  (cast list as per AFI database)
