Kamran Esfahani, a dentist living in Stockholm, agrees to spy for the Mossad after he’s recruited by the chief of a unit tasked with running assassinations inside Iran. At Glitzman’s direction, Kam returns Tehran and opens a dental practice there, using it as a cover for the Israeli intelligence agency. But when Kam tries to recruit an Iranian widow seeking to avenge the death of her husband at the hands of the Mossad, the operation goes terribly wrong, landing him in prison under a sadistic officer called “General.” After enduring three years of torture in captivity, Kamran Esfahani sits in an interrogation room across from the General, preparing to write his final confession. Kam knows it is too late to save himself. But he has managed to keep one secret, and he just might be able to save that.
