Cast & Crew
James Herbert, an eccentric millionaire apparently on the brink of death, sends for his four most likely heirs: Billy, Tully, Nancy, and Mrs. Rackham. He gives each of them a sealed letter with instructions not to open it until his death. All four disregard the old man's wishes and open their letters, learning that Herbert has hidden a fortune in bonds in a haunted house. The four go there and meet with a mad doctor, a caretaker, a sleepwalking girl, and a beautiful nurse. After a night of strange noises, weird happenings, and screams, Herbert appears and explains that the ghosts and ghouls, hired from central casting, were part of a test to discover the true nature of his presumptive heirs. Billy is then designated as the rightful heir.
