The Inspector Lynley Mysteries (Series 5) (2006)

Lynley finds himself suspended from duty accused of having threatened a witness. As a result, DS Havers is temporarily re-assigned to DI Fiona Knight. They look into the murder of Edie Covington who was found dead in her car at the bottom of the lake. Edie was well known to many in the local area and had incurred the wrath of Owen Hardourt-Baines, a local land developer who had hoped to develop the lakeside into a housing estate. The police think they have a motive and forensic evidence that points to a killer, but in the end must look elsewhere. Although suspended, Lynley can't help but involve himself in the case. In his personal life, things are looking up when a reconciliation with his wife seems to be in the offing.
