The author is a German, Jörg Bong, who lives between his country and Brittany.
This is the fifth volume in the series "A Brittany Mystery" featuring Commissaire Georges Dupin. The protagonist has been "banished" from Paris to this area at the end of the earth (finis terrae) and slowly, with the help of his secretary Nolwenn, he becomes more and more familiar with "life" in Brittany. The novel ends by leaving open the fantasy of a local legend about a great cross of gold.
The action is centered on Île de Sein and the entire coastal area with Brest and Quimper as urban centers. It begins in the fishing auction room in Douarnenez, where a young fisherwoman, who used to sell her catch of the day, is found murdered. Soon another victim appears, also stabbed in the neck: a young woman dedicated to the study of dolphins in the protected area of Parc Iroise. The corpse of an old retired professor appears on the beach, near the house where he lived alone.
Legends of pirates and old Celtic myths are mixed with the reality of a mafia-like character, who dominates the fishing industry and competes with small fishermen.
In addition to an interesting criminal case, the author takes pleasure in describing the landscape, gastronomic specialties and local legends and superstitions. A tribute to the Brittany of which the author seems to be in love.
From the moral point of view, there are no inconvenient descriptions. The reader should be aware that this work of fiction reflects a part of reality and lacks, for example, transcendent contents.
