Newly-appointed DI Jack Striker, of Greater Manchester Police’s Major Incident Team, has a dark secret, one that would land him in prison. Striker’s first case seems a straight-forward gang-on-gang slaying, until a notorious youth is found hanged. Before any chance to investigate, bodies begin stacking up. With the hot breath of the brass burning his neck, including hardfaced DCI Maria Cunningham who’s onto him, Striker knows this case will make or break him. The media-dubbed "Hoodie Hunter" mixes MO’s, leaving few leads, and Striker recognizes the work of a highly-skilled vigilante killer. When Striker’s nephew is put into a coma, it becomes personal. Desperate, he runs an unofficial op with his trusty colleagues, the stunning DC Lauren Collinge and the un-PC DC Eric Bardsley, placed in the line of fire.
