Peter Grant returns in an enjoyable mystical detective turn. Despite subject matter no less macabre, I do find that these books have a noticeably lighter feel than, say, Paul Cornell's Shadow Police or Mike Carey's Felix Castor (my personal favourite). There are ups and down to the lightness. You have some glorious hard-boiled detective metaphors (one character barges into a scene "like an overdue tax demand"), but this did all just feel a bit insubstantial. I'm not normally one for guessing mysteries, but I did manage to work out a fairly substantial bit of the plot by the end of chapter two. Fun, but not firing on all cylinders, perhaps.
