I have been reading/listening to the first four books in this urban fantasy / police procedural series featuring a London policeman who becomes a trainee wizard. The author is a former writer for Doctor Who, but it is actually the police angle that I have found more interesting in the books. While it has a paranormal aspect, not unlike the Laundry novels or other similar series, the repeated grounding of the character in London police procedure is very interesting. As Peter goes from situation to situation, he is constantly explaining how his experience as a police officer is influencing what he does and what he is thinking about, and I have found that very entertaining. Overall a good series.
