Publisher's Synopsis
When a young woman is found chained to a post at low tide in the river Thames, no-one can understand how she came to be drowned there. At the Peculiar Crimes Unit, Arthur Bryant and John May find themselves dealing with an impossible crime in a very public place. Soon they discover other victims, but as the investigation extends from Libya to London, it proves as murky as the Thames itself. The detectives get involved in some serious messing about on the river. In an adventure that's as twisting as the river, will there be anything left of the Peculiar Crimes Unit when it's over?
