What happens

Inspector Tanner uncovers the full backstory of Sir William Ponson's marriage to Ethel Osborne, revealing that she was previously married to Tom Dale, who was believed lost at sea. Tanner deduces that the arrested man, William Douglas, may actually be Edward Dale, but a confrontation with Mr. Clayton yields a stunning revelation: the prisoner is Tom Dale, alive and in disguise. This exposes that Sir William's marriage to Ethel was bigamous, making Austin and Enid illegitimate, and explains the motive for blackmail.
