Thomas Fool is an Information Man, an investigator tasked with cataloging and filing reports on the endless stream of violence and brutality that flows through Hell. His job holds no reward or satisfaction, because Hell has rules but no justice. Each new crime is stamped "Do Not Investigate" and dutifully filed away in the depths of the Bureaucracy. But when an important political delegation arrives and a human is found murdered in a horrific manner--extravagant even by Hell's standards--everything changes. The murders escalate, and their severity points to the kind of killer not seen for many generations. Something is challenging the rules and order of Hell, so the Bureaucracy sends Fool to identify and track down the killer.
