Thames Valley has a new Superintendent – DSU Wainwright – young, charismatic and ruthless, charged with pushing through big reforms. Her in-tray is full of problems – and at the top of the pile is the problem of Wilkins and Wilkins. Trailer park boy DI Ryan Wilkins, interesting looking in baggy trackies and over-large lime-green puffa. In his personnel file is a handwritten note scribbled by the outgoing Super: Do not, repeat not, give him responsibility. And posh boy DI Ray Wilkins, improbably handsome in navy blazer and tan chinos: Thinks too highly of himself. More experience needed at the wet end. Their previous investigations – though somehow successful – were models of disorder and dysfunction. The new Super needs to take action. Theres been a shocking murder in the heart of Oxford, the stabbing of a security guard during an attempted armed robbery.
