The Inspector Lynley Mysteries: In the Guise of Death

While in Cornwall on separate holidays, Detective Inspector Thomas Lynley (Nathaniel Parker) and Sgt. Barbara Havers (Sharon Small) learn that a local horse trainer was found hanged in his stable, but they rule out suicide after discovering that the man had been drugged. In search of answers, the detectives investigate the local equestrian scene, which leads them straight to Lady Sarah Keach (Stella Gonet) -- a friend of Lynley's mother.
