“Tricky business” - this is what Ernest Hemingway called the group of fighters he organized in Cuba against the Nazis and their accomplices. But behind the backs of the soldiers fighting the enemy, the powerful intelligence bosses, Edgar Hoover and Heinrich Himmler, who had colluded, carried out their vile deed. And ships and planes, betrayed by their own, perished, and a tragic bell rang over millions of victims... They were so different - the author of great books and his shadow, an unknown FBI agent who had not read a single one of them. But love for their homeland and hatred of Nazism forced them to stand shoulder to shoulder, not afraid of German bullets. And win.
