But when the bodies of three unidentified men wash up on the beach, the witnesses are faced with an impossible decision: report the discovery and open up the island to grisly inquiries, or conceal the terrible truth?

But after they dispose of the evidence, their act of deception continues to haunt them, bringing waves of suspicion and misfortune to the island. A detective arrives from the mainland, making their secret even harder to keep and threatening to destroy the very community they tried so hard to protect.

With the blend of suspense, keep observation, and wit that has made Philippe Claudel's books international bestsellers, Dog Island challenges our deepest assumptions about ourselves and offers a fierce and tragic fable for our times.
