A few days later, Donald's father Raymond Arlington (Charles Dingle) arrives, determined to ensure that his son gets the inheritance. Duprex (David Hoffman), Ingram's attorney, is "persuaded" (by the agreement of his getting a third of the estate) into helping Raymond overturn the new will in favor of the old one, telling him that there is evidence indicating Ingram was of unsound mind. That night, Duprex is strangled by an unseen assailant. Castanio begins to investigate. The Arlingtons try to search for the old will, while suspicion falls on Cummins after he tries to remove several expensive old books from the manor house. That night, everyone hears Ingram playing the piano in the main hall, but when they go to check no one is there. Donald is attacked and almost choked to death by a hand and witnessed by Castanio. He discovers that someone has broken into the Ingram mausoleum and that Ingram's left hand has been cut off. But it seems impossible for anyone to have gotten in or out.
