The Killing Tide, Bannalec - B

                Over the course of twenty-four hours, Commissaire Dupin is faced with three murders. Two are young women, a fisherwoman and a dolphin researcher, both of whom live on the Ile de Sein off the Brittany coast, and improbably, a seventy-five year old retired male virology professor.  Each book in this series teaches about Brittany, and this one is about the fishing industry, where major firms and small fishermen square off. In the end, human greed is the motive. A golden cross of vast archaeological value had been found and is the motive for the murders.
