Pierre Nord’s gripping novel «Double Crime on the Maginot Line» is the first French spy novel. In connection with the threat of attack by Nazi Germany, France is building powerful defensive fortifications in the northeast, the so-called Maginot Line. Everyone feared the penetration of German spies into the defense secrets of this marvel of military engineering. The hero of the novel is by no means a Great Detective, but merely a good soldier in the service of his homeland.
