The Secret of Sarek (originally published in French as L'Île aux Trente Cercueils, 1919) is a mystery thriller by Maurice Leblanc, best known as the creator of Arsène Lupin. The novel centers on Véronique d'Hergemont, who, seventeen years after being kidnapped by the duplicitous Count Alexis Vorski and forced into a false marriage, learns she may have a son still living. Her search leads her to the remote, mist-shrouded island of Sarek off the coast of Brittany — a place haunted by ancient Celtic prophecy foretelling that thirty coffins must be filled before a sacred stone yields its secret. As Véronique navigates a labyrinth of betrayal, occult ritual, and wartime intrigue, she confronts enemies both human and seemingly supernatural. Leblanc weaves Breton megalithic legend with pulse-driven adventure plotting, producing a novel that blends Gothic atmosphere with the propulsive mechanics of popular serial fiction. Published in the immediate aftermath of World War I, the book reflects the era's preoccupation with hidden forces, collective trauma, and the fragility of civilization. It stands as one of Leblanc's most ambitious standalone works, demonstrating his range beyond the Lupin series.
