The river Thames is London's most important yet neglected artery When a young woman is found chained to a post in the tide no-one can understand how she came to be drowned there At the Peculiar Crimes Unit Arthur Bryant & John May find themselves dealing with an impossible crime committed in a very public place Soon they discover that the river is giving up other victims but as the investigation extends from the coast of Libya to the nightclubs of North London it proves as murkily sinister as the Thames itself That's only part of the problem; Bryant's rapidly deteriorating condition prevents him from handling the case & he is confined to home To make matters worse May makes a fatal error of judgement that knocks him out of action & places everyone at risk With the PCU staff baffled as much by their own detectives as the case the only people who can help now are the battery of eccentrics Bryant keeps listed in his diary but will their arcane knowledge save the day or make matters even worse? Soon there's a clear suspect in everyone's sights
- the only thing that's missing is any scrap of evidence As the detectives' disastrous investigation comes unstuck the whole team gets involved in some serious messing about on the river In an adventure that's as twisting as the river upon which it's set will there be anything left of the Peculiar Crimes Unit when it's over?
