The Missing Corpse (Dupin series #4)

"Delicious Brittany mysteries... If this isn't heaven, it's close enough." ―The New York Times

Along the picturesque Belon River, home of the world famous oyster beds, between steep cliffs, ominous forests and the Atlantic Ocean, a stubborn elderly film actress discovers a corpse. By the time Commissaire Dupin arrives at the scene, the body has disappeared. A little while later, he receives a phone call from the mystical hills of Monts d'Arree, where legends of fairies and the devil abound: another unidentified body has turned up. Dupin quickly realizes this may be his most difficult and confounding case yet, with links to celtic myths, a sand theft operation, and mysterious ancient druid cults.
