Ten miles off the coast of Brittany lie the fabled Glénan Islands. Boasting sparkling white sands and crystal clear waters, they seem perfectly idyllic, until one day in May when three bodies wash up on shore. At first glance the deaths appear accidental, but as the identities of the victims come to light, Commissaire Dupin is pulled back into action for a case of what seems to be cold-blooded murder.

Ever viewed as an outsider in a region full of myths and traditions, Dupin finds himself drawn deep into the history of the land. To get to the bottom of the case, he must tangle with treasure hunters, militant marine biologists, and dangerous divers. The investigation leads him further into the perilous, beautiful world of Glénan, as he discovers that there's more to the picturesque islands than meets the eye.

Steeped in the enchanting atmosphere of Brittany and peppered with wry humor, Murder on Brittany Shores is a superbly plotted mystery that marks the return of Jean-Luc Bannalec's international bestselling series starring the cantankerous, coffee-swigging Commissaire Dupin.
