Jeanne Doe heads an operational unit in the counterterrorism division of the DGSE. She is leading a clandestine counter-interference operation on an unprecedented scale: infiltrating radical Islamist networks, using Muslim women, through a maternal and child protection center. When one of their sources is found murdered, the mission is thrown into turmoil. Is it a coincidence or a macabre warning? And is it linked to Bartex, Jeanne’s former lover whom she met during a mission, who asks her at the same time to delete the data from her computer? Before he dies, he leaves her an encrypted file: the work of a lifetime as a spy that no one wants to see come to light.
A spy and action novel, Le Cercle de Thor plunges us into a tense parallel world, that of clandestinity within the secret services themselves. Between paranoia and hidden truths, what happens when we can no longer distinguish partners from enemies?
