This is such a fun series...a blend of police procedure and supernatural thriller...with a good sense of humor. Start with Midnight Riot!

3rd title in the Rivers of London series

Again, the mystery of the week just isn't very interesting. Far more intriguing are the major arcs - Lesley learning magic and recovering from extreme trauma, Peter learning more about the magical world, the reader learning more about how magic was used during WW2, the Faceless Man being a creepy bugger, the Rivers and their internecine politicking. I wish the series would spend more time on those stories and less on random murder investigations. Also available as a streaming audiobook on Hoopla.

Detective novel, set in current day London, England, focused on the magic division of the Police. (A very small division - only 3 officers!)
An Urban Fantasy, spiced with humour, and based on some serious research into the train system and underground history of the city. A very enjoyable read - I'll be looking for the other books in the series.

These mysteries about constable Peter Grant, who wants to be on the murder squad but ends up apprenticed to the last wizard in England (Detective Chief Inspector Nightingale of Scotland Yard) are an excellent blend of mystery, fantasy, humour, and horror. Peter's first person narration is immediately engaging, and the mysteries combine magic with the traditions of police procedural very well. The setting itself becomes a character, in more ways than one, as the gods of the Thames get involved. My very favourite of the series is book two, Moon Over Soho; this one lacks a bit of the punch of that, but is still an excellent read.
