Roger Pollard was a member of a London criminal gang run by Michael Shand. When Pollard is found on a beach shot through the head, DI Lynley and DS Havers assume Shand is responsible. They are surprised however to learn that Pollard had grown up locally, making him an easy target for anyone trying to learn his whereabouts. Havers is in her element as she used to go to a holiday camp in the area as a child. She becomes convinced that the death of a young boy from the holiday camp, Martin McRae, some twenty years before is the key to solving the crime. Written by garykmcd

Inspector Lynley and his partner Barbara Havers investigate "One Guilty Deed" in this season 5 episode.

When a criminal who is turning state's evidence is murdered in his home town, Lynley and Havers get the case. The home town is seaside and a place where Havers spent many happy childhood summers with her brother in a seaside caravan. She's thrilled and excited to be there. There is only one caravan left that she and Lynley share; he's less than thrilled about roughing it.

Havers befriends a woman who lives in the town, whom she remembers from her childhood. As she and Lynley attempt to sort through what happened, the gangster they suspect of murdering their victim is also killed.

Havers begins to suspect the murders may be tied to the death of a little boy who had drowned years before.

What makes this episode so good is that it starts in one direction and goes into another, and also we get to see a new, cheery side of Havers as she belts out karaoke at a local club.

Lynley is in a foul mood, particularly at the beginning. Both actors do a wonderful job, and the seaside resort looks like incredible fun, particularly an old building with turquoise turrets. Being American, I was not familiar with caravan parks or, in fact, caravans, so the episode was especially fascinating.

This is one of the better Lynleys, mixing a dark, sad story with some lighter moments.
