With unprecedented and unvarnished access to Hampshire Constabulary, a typical large provincial police force in the grip of profound change, this three-part series follows the investigation of major crimes. A murder investigation starts with a body burned beyond recognition but with no clues to the identity of killer or victim. An arson attack consumes a Portsmouth block of flats & destroys evidence of who set the fire. And a rape case is her word against his, with not much evidence to go on.
