This seventh book in the Rivers of London series is shorter than the others, just over 100 pages. I was pleased to be dealing with ghosts again as they have a lot of scope for interesting situations and glimpses of history.
I also enjoyed the return to dealing a little with river spirits, bringing it full circle. This one has an old fashioned Mystery element in that someone has been kidnapped and cryptic hints from ghosts are all Peter Grant and company have to go on to try to find the missing girl.
The book makes an enjoyable, short read and I feel returns to the vibe of the first book in a way that is satisfying to someone who has been reading through the whole series.
