In this classic espionage thriller, a humble language teacher vacationing in a small French coastal town finds himself embroiled in a high-stakes game of international intrigue when he is mistakenly accused of being a spy. To prove his innocence, he must identify the real spy among the eclectic guests staying at his hotel, using only his wits and the help of a few reluctant allies. As he navigates a labyrinth of deception, danger, and diplomatic tensions, the protagonist discovers that in the shadowy world of espionage, trust is a commodity as scarce as it is valuable. This gripping narrative masterfully combines suspense, character study, and a vivid portrayal of pre-war Europe on the brink of conflict.
