In the humorous trilogy The Rivers of London by Ben Aaronovitch, we can follow the adventures of Peter Grant, apprentice in the last department for magical events of the London Metropolitan Police. Caught between a police force that does not want to hear about magic any more than they have to and a superior office who is stuck in the 40s, Grant is drawn to adventures with river gods and decade-old wraiths.
The trilogy is a fast read and full of dry, British humor. Prejudices flow freely, which is a bit amusing but can go too far for my taste. For example, in the first book, Detective Seargeant Stephanopoulos is described as a woman you do not mess with, a strong woman with short hair, stocky, etc.—“a typical lesbian.” That’s just one example of where the usually good humor just goes too far. Stephanopoulos has a come-back in the second book, making her much more likable, though.
The second book was by far the best in my opinion. The author even managed an ending that really got under my skin, something I didn’t quite expect in such humorous novels. All in all, a good choice for a quick, funny read.
