Know Thine Enemy--Last of Inspector Lynley
23 December 2012 | by ctyankee1See all my reviews

This is the last episode of the Inspector Lynley Mysteries.

The episode is about young teenage girls showing up dead. It appears they were sadistically hurt and held captive.

Some witness say a woman with red hair was seen talking to two of these teens along with a man. A well known writer is questioned when his wife, a red head is beaten up and goes to the hospital. The DJ boyfriend of one of the girls is questioned is also considered as a suspect.

Tania the redhead is played by Honeysuckle Weeks the wife of a author that beats her up. Ms Weeks is a great actress she plays a driver for Inspector Foyle in another series called "Foyle's War" which is a British series that is wonderful and touching.

Lynley and Havers question different people as well as the parents of the girls gone missing. They also question a writer and his wife, the red head.

This episode was not to bad, lots of different conclusion and questions. Also internal problems with supervisors. I am kind of sad this is the last of the series. I do think an hour and a half is too long.

Nathaniel Parker/ Lynley and Sharon Small/Barbara Havers make this series interesting and I am sure will star or have acted in many videos/movies/series since Inspector Lynley Mysteries. I have a lot of respect for both of them.

The ending is a surprise.
