This ground-breaking novel is one of the first, if not the first, inverted mysteries, in which the killer is known by the reader all along. It’s a cleverly written and darkly comedic novel for fans of *The Poisoned Chocolates Case* and *Murder in the Basement* from our series, along with the books of Richard Hull. Tightly paced and cleverly defying the conventions of the classic detective story, this 1933 novel remains a milestone of the inverted mystery subgenre.
