A voice in the night

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. There's been a shocking murder in the heart of Oxford, the stabbing of a security guard during an attempted armed robbery.
