Harriet Walter reads Episode Eight of a dark and mysterious thriller by Sian Busby. The investigation follows a new twist.

The sham of The Frobishers' marriage is now out in the open. The couple had been trying to make a go of things since Walter came back from the war 'for the sake of their son', but Walter has admitted that he knew that his wife had affairs, and finally Lillian had become aware of Walter's deceit too. Evelyn's revelation that Lillian had met a spiv called Dennis in a café has sent the enquiry off in a new direction and Cooper is now armed with an artists' impression of him. Bright eyed Policewoman Tring has made some interesting discoveries and reveals, to Cooper's devastation, that she wants to join CID.

A Commonplace Killing by Sian Busby is abridged by Lauris Morgan Griffiths and produced by Sarah Langan. Show less
