Castor has reluctantly returned to exorcism after the case of the Bonnington Archive ghost convinced him that he really can do some good with his abilities ('good', of course, being a relative term when dealing with the undead). But his friend, Rafi, is still possessed; the succubus, Ajulutsikael (Juliet to her friends), still technically has a contract on him; and he's still - let's not beat around the bush - dirt poor.
Doing some consulting for the local constabulary helps pay the bills, but Castor needs a big, private job to really fill the hole in his overdraft. That's what he needs. What he gets, good fortune and Castor not being on speaking terms, is a seemingly insignificant 'missing ghost' case that inexorably drags himself and his loved ones into the middle of a horrific plot to raise one of Hell's fiercest demons.
And when Satanists, sacrifice farms, stolen spirits and possessed churches all appear on the same police report, the name of Felix Castor can't be too far behind . . .
In Carey's fine second supernatural thriller (after The Devil You Know), FelixCastor, an exorcist with paranormal abilities who lives in a near-future England where ghosts and zombies are an accepted reality, is suffering from guilt after an attempt to separate a master demon, Asmodeus, from a friend, Rafi, ended with the evil spirit gaining even more control over Rafi. Fortunately, a new case provides distraction. Melanie and Stephen Torrington, who believe that their young daughter's ghost has been kidnapped, hire Castor to uncover some last trace of their child. The investigator soon finds that his employers haven't been fully truthful with him as he starts crossing paths with lycanthropes and other undead beings. Carey's imagined universe has some nice satiric touches (the term "zombie" has been designated a form of hate speech), and the well-developed main character appears more than capable of carrying a series for many books to come.
