The seventh Peter Grant novel and, probably, the last I will bother reading. The problem for me is that Aaronovitch seems to find most interesting the characters I find least compelling (the various policemen and women who are almost entirely interchangeable, Peter’s riparian love interest Beverley, and, to be honest, Peter himself) while sidelining those whom I find most compelling, in particular Nightingale and Lesley. Also, having finished the book, I found out that some of these amorphous characters had been introduced via a couple of graphic novels that Aaronovitch has produced. It’s all a sure sign of a novel series being expanded into a world franchise: good sense from a business point of view, less so from an artistic one.
