Within the DGSE, the General Directorate for External Security, there’s a division known as the Office of Legends (BDL) that trains and oversees the most crucial agents of the French intelligence network: the Clandestine operatives. These agents are deployed in hostile territories with the task of identifying potential informants. They operate “under legend,” meaning they assume entirely fabricated identities, living in constant deception for many years. Our protagonist has just returned from a six-year undercover mission in Damascus. However, defying security protocols, he refuses to relinquish the false identity he used in Syria, thereby jeopardizing the entire system.
