Forty Detectives Later (1960) A private detective, William Tyre, is the 41st detective hired by Mr. Dean to find his wife's murderer. Only Dean now says he's found his wife's murderer, a bookstore owner named Otto, and all he wants is for Tyre to arrange for the two to meet. In reality, Dean wants Tyre to kill Otto, but Tyre declines and arranges only for the two to meet. Turns out there is a relationship between Otto and Dean, but it's not quite as expected.
