Another three two-part episodes from the ITV drama series based on the crime novels by Peter Robinson. Stephen Tompkinson stars as the tenacious and stubborn Detective Chief Inspector Alan Banks, who unravels a string of disturbing murder mysteries aided by his feisty and ambitious young assistant, DS Annie Cabbot (Andrea Lowe). In 'Strange Affair', Banks, assisted by icy DI Helen Morton (Caroline Katz) while Annie is on maternity leave, investigates the murder of a woman found shot dead in her car. In 'Dry Bones That Dream', Banks is called in to investigate the death of a mild-mannered accountant, Keith Rothwell (Dominic Mafham), who appears to be the victim of a contract killing. Finally, in 'Innocent Graves', the strangling of a wealthy financier's 16-year-old daughter unearths a complex web of lies and secrets for Banks to solve.
