The cover might not give too much away, but this is a solid first novel from a new crime author. If you're familiar with the TV detective mysteries Prime Suspect and Cracker, you'll be at home on the streets of Manchester as the charismatic detective and forensic specialist follow the trail of a masked and inventive serial killer.
Although the last act comes very late into the book (20-odd pages from the end and they still don't know whodunit) and wraps up quickly, protagonist Tom Caton is a well-drawn sympathetic leading man and is surely good for a few more adventures.
Since the book is of the publish-on-demand kind you may need to overlook distractions from occasional typos in the text, but all in all The Cleansing is a fitting addition to the police procedural genre, and Bill Rogers is a new author worthy of our support.
