In Hell, murder is supposed to be impossible—after all, everyone's already dead. But when a demon bureaucrat turns up permanently "snuffed out" in the Infernal Records Office, pandemonium breaks loose. Enter Bartholomew "Bart" Cringe, a washed-up Victorian detective damned for plagiarism, now working as Hell's most reluctant gumshoe. Tasked by Lucifer himself to solve the case, Bart is plunged into a world of sarcastic imps, corrupt soul-traders, and rival devils with suspiciously squeaky-clean alibis.

With Hell's infernal justice system on the line, Bart must crack the uncrackable case—before someone figures out how to "kill" the Devil himself.
