The second Aaronovich book about a police constable inducted into the Met police’s now very limited (him and an inspector, plus their vampire maid) magical services division. It neatly follows on from the first without missing a beat and sets up a brilliant serial killer piece which gives the magical police procedural a great workout. The main character is further developed, as is the background to the world and the other major characters (including his boss and his family). The musical link is nicely played through in multiple interlocking themes, while no punches are pulled in the human capacity for screwing up and around and, well, just plain screwing, too. I’m really looking forward to the third book which I have on my “order when available” reminder list (I think it’s in hardback now but I’ve got the TPBs of the first two so will wait for that edition).
