A rather contrived group of ladies set out to solve a series of murders in the Thames-side town while getting on the nerves of the local police. They are led by a sixty-something busybody with an unexplained knowledge of WW2 pistols who goes skinny-dipping in the river from her private boathouse where she also keeps her punt. Also included are a dog-walker with a van that's too small for the job and an unhappily married vicar's wife. There are a number of other unlikely characters sprinkled around. The scenery is pretty and some of the houses are suitably grand but running one thin storyline over two two-hour slots is stretching things to the extreme.
