Some bizarre things have been happening to the eccentric Hatter family. First, the body of York Hatter is recovered from the ocean. But he didn't drown. He died of poison. Next, another poisoning occurs in the Hatters' old mansion in New York's Greenwich Village. This time the police have a witness. But what a witness! She is a blind, deaf mute. Naturally the authorities call in Drury Lane—retired Shakespearean actor, matinee idol, master of disguise, and amateur sleuth.
