It is great blend of urban fantasy, police procedural, and mystery. Peter Grant is a strong lead character but there is a nice mix of secondary characters, including London itself, and with enough action to keep the plot moving. Highly entertaining.

The narrator, Kobna Holdbrook-Smith, does a great job with the voices and personalities involved. It was like listening to a radio drama. And along the way you get a great sense of London as both a place and as an identity.
