Another turn with our largely unhappy main character Felix "Fix" Castor, told in first person but in dense, literary prose full of detail and comments, often snarky, often self-deprecating, on much of the detail. Three stars in Goodreads' code means "I liked it," and that's quite true of the second half, in which the action picks up and three apparently separate story lines begin to intertwine and, by the end, become a complex adventure.
All three story lines are signaled in the publisher's blurb, thank goodness, and most of the blurb is reprinted at the head of this Goodreads book page. One little point: the original blurb makes it clear that the lawyer in question has a legal claim on John Gittings's corpse; it just feels like he's stealing it, especially after the burial. Gittings's ghost is indeed unhappy and has "turned geist" as Fix puts it, tearing up the living room but never harming his grieving widow.
Gittings and Fix are both exorcists, in a slightly alternate London, England, where ten years ago ghosts emerged into public view; most of them are harmless, but exorcists do a thriving business banishing the ones that cause trouble. Each exorcist uses an individual technique--Fix with his tin whistle and Gittings with drums, for example. Fix is sensitive to people's touch and that extends to ghosts; with his little instrument (always in his greatcoat pocket) he finds a melody that captivates the ghost, and when he stops playing the ghost vanishes for good.
So now the ghost of an American female serial killer, executed forty years ago, has turned up in London, and I hope it's not a spoiler to tell you that the ghosts in this story are much more powerful than the ones Fix has encountered before. The title refers cryptically to that power, and the words of the title show up on page 315, as the situation becomes clearer to Fix and to us readers. It's a long story, and it certainly tested this reader's patience, but four stars for the final chapters; I really liked the way it turned out.
As usual, Fix takes a lot of physical damage in the fashion of a hard-boiled detective story and carries on fighting in a way that strains credibility, especially when his chief weapon is the melody he's trying to play!
As the blurb hints, Juliet the demon and Nicky the zombie play major roles in this story. So does Fix's unrequited love interest Pen, who enlists his help to keep their friend Rafi in safe custody. The demon Asmodeus has possessed Rafi for years, and Fix feels responsible for what's happened. That puts a somber tone into the whole story, adding a desperate struggle to what's otherwise a lively, suspenseful adventure full of perilous action...in the second half at least.
