Two bikers, one name, invisible wounds.

Marco and Guy survived the unthinkable. Since then, they've been fleeing silence?one fills it with noise, the other watches for the void. Only one solution: the road. The west. The ocean.

On the island of Oléron, they meet Léa, a historian passionate about a forgotten legend. A singing lighthouse. A light that doesn't guide, but calls.

Very quickly, the investigation leads them to the "king of lighthouses," Cordouan, a majestic stone tower standing facing the Atlantic. But what its walls conceal surpasses anything they could have imagined.

Because the lighthouse wasn't built on a rock. It was built on a heart. A heart that still beats. And that remembers.

To close what they have opened, Marco, Guy and Léa will have to confront their own ghosts, offer their most precious memories... and accept that some sacrifices leave nothing behind.

Because in Cordouan, the light doesn't show the way. It chooses you.

Between road trip, claustrophobic suspense and intimate quest, The Dubois and the Light of Cordouan is a standalone investigation in the Dubois series, where the mystery of ancient lighthouses is intertwined with the memory of those who dare to confront them.

They thought they were escaping their past. The sea had always been waiting for them. And some calls never die.
