The legendary Hesselthorn Puzzle Box has disappeared.
Said to contain a powerful djinn that can grant eternal life to whoever opens it, every demon mobster and werewolf gang member in the city will do whatever it takes to get their claws on the box first.
As one of the most valuable objects insured by Crimson Seal, it's Tim Lovecraft's job to find the box before the criminals do. Tim is convinced that the theft is an inside job, but as his investigation progresses, he discovers that nothing - including Crimson Seal itself - is what it appears to be.
The uproariously creepy fourth book in the "Demonic Indemnity" series finds our reluctant hero confronting a familiar source of black-hooded evil, trying to date again after a bad breakup, and playing host to a variety of freeloading entities, some of whom leave ectoplasm on the furniture.
