Contains a devious and diabolical plot of multiple murder to which a solution of equal merit is provided.
Mr. Fathom, a prodigious investigator, is challenged by nothing less than the Perfect Crime. When the members of an exclusive London club dedicated to the Thomas de Quincey view of homicide as a fine art learn that one of their number had been involved in a "perfect crime" (before his own mysterious death), they turn as a man to Mr. Fathom. Because he is an addict of exotic statuary, Mr. Fathom accepts the case; his fee will just cover the cost of a Kneeling Gorgon in bronze he very much covets.
The case is complex, but beautiful in its symmetry, encompassing absolute equality of motive, equality of opportunity, and equality of clue. Our Olympian sleuth grills his subjects with a vengeance, among whom are the murdered man's widow, mistress, and benefactee. The denouement of this singular whodunit is surprising, masterful, and thoroughly convincing.
In the US edition, Mr. Verity's name has been changed to Mr. Fathom.
The U.S. edition was published as written by Anthony and Peter Shaffer.
