When Ed Talbert arrives at Union Station in Los Angeles, he's accompanied by Kitty Delany, who he met on the train and who is helping the elderly man. Ed calls his son, Carl, a nightclub piano player but, before the call is even finished, Ed Talbert dies from a heart attack. At the time, Steve Radom was standing by Talbert. The police officer who investigates the death at the station is Danny Talbert, a LAPD Sergeant, who is the son of the dead man. Carl consults Perry Mason and says that he subsequently received a call from Steve Radom saying that his father owed him $10,000. Radom, it turns out, is a well-known gangster and Carl's brother, Danny, pays him a visit. Perry makes an appointment to see Radom about the debt. He is approaching Radom's cabin when he hears shots and sees Danny running away from it. When Radom is found dead, Danny is arrested and charged with murder. There are several people who may have wanted him dead including business partners in Los Angeles. A family secret is at the root of it all.
