The story of the Zipper is now in graphic novel form! Dr. Julio Antonio del Marmol is arrested by the United States Secret Service on a counterfeiting charge. They can find no information about him which leads them to wonder WHO he is. We go back in time to discover that he was a deeply implanted spy for the West on the Castro regime in Cuba that was forced to flee when his cover gets blown. Undeterred, he makes a unique agreement with United States intelligence: he will continue to work WITH them, but not FOR them. Given new equipment and training, he returns to Cuba to continue his battle against totalitarianism around the world. Available at Amazon.
