Query: Banks Number Nine: Worthwhile

A young man is beaten to death in an alleyway at night. The plot thickens when his identity is discovered: Jason Fox, a leading light of the Albion League, a thoroughly unpleasant extreme right racist fringe group. As DCI Banks and DC Susan Gay piece the details of Fox's nasty story together, their lives complicate in other ways. Susan is embarking on a relationship with Gavin, a colleague from regional HQ. Meanwhile the state of Banks' marriage is going from bad to worse as is his relationship with his boss Chief Constable Jimmy Riddle. This book, whose British title is `Dead Right', didn't seem to me to be quite as good as its predecessor `Innocent Graves' but is nonetheless another pretty strong and worthwhile procedural from Robinson.
