S05E01 - Natural Causes

Since Lynley's (Nathaniel Parker) arrest and suspension for threatening a suspect, Havers (Sharon Small) has been without a partner. She begins a new case in Kent alongside the heavily pregnant, no-nonsense Detective Inspector Fiona Knight. Together, they investigate the murder of Edie Covington, whose body has been discovered in a local lake. Back in London, Lynley attends a disciplinary hearing to determine whether he can return to work. Following the hearing, Lynley begins to help Havers and Knight with their investigations. But, as the case unfolds with the discovery of another body and a kidnap, will Lynley's unofficial involvement jeopardise his efforts to be reinstated? Guest stars include Liza Tarbuck as DI Fiona Knight, Adrian Rawlins as Tim Sumner, George Costigan as Owen Harcourt Baines, Saskia Reeves as Eileen Humbolt, and Nicholas Gleaves as Dr Simon Wilson.
