A twisty tale rife with intrigue, danger mystery, and murder from the author of the acclaimed medieval mystery A burnable book. Though he is one of England's most acclaimed intellectuals, John Gower is no stranger to London's wretched slums and dark corners, and he knows how to trade on the secrets of the kingdom's most powerful men. When the bodies of 16 unknown men are found in a privy, the Sheriff of London seeks Gower's help. The men's wounds - ragged holes created by an unknown object - are unlike anything the sheriff's men have ever seen. Tossed into the sewer, the bodies were meant to be found.
