The third entry in Kernick's loosely knit London gangland series opens with a bang, as the ironically named Colombian narcotics sting, Operation Surgical Strike, dissolves into a bloodbath when uninvited thugs make the scene. Among the dead is the partner of nasty undercover cop Stegs Jenner. Things get perplexing fast as DI John Gallen, whose recent promotion seems to have rubbed off some rough edges, finds the probable leak shot dead and must include Stegs among a dwindling pool of suspects. In Kernick's world, coppers mostly come in three varieties: bent, twisted, and broken; not surprisingly, then, much of this book's suspense hinges on just how far Stegs will go and whether we will end up respecting or loathing him when the smoke has cleared. Although Stegs is not as compelling as Milne, the antihero at the black heart of the series debut, The Business of Dying (2003), this remains a solid, morally ambiguous mystery with some great tricks up its sleeve. Kernick belongs on the second tier of Brit noir, right below Bruen, Lawrence, and Harvey.
