An all new adventure for Aaronovitch's laconic, way-past-cool but slightly geeky trainee wizard and budding detective, Peter Grant. This title is set between "Broken Homes" and "Foxglove Summer" in the "Rivers Of London" continuity.

Ben Aaronovitch has written for TV, his credits including Doctor Who and Casualty; his Rivers of London novels have been international bestsellers and he has finally fulfilled his dream of adding a comic to the series; in this he has been joined by fellow writer and regular Doctor Who contributor Andrew Cartmel. The series is drawn by yet another Doctor Who creator, Matthew Dow Smith, who has also illustrated the likes of Hellboy, Supernatural: Origins and Sandman Mystery Theatre.
