Kirst's book "Die letzte Karte spielt der Tod" was a novel that offered a considerably more realistic picture than Meissner's romanticised portrayal of Sorge. Kirst portrayed Sorge as an existential hero, a deeply-traumatized veteran of World War I, whose sleep was constantly disturbed by horrific nightmares of his war service, and when he was awake, he suffered from frequent panic attacks. Kirst's book depicted Sorge as a "lonely, desperate" man, a tragic, wounded individual with a reckless streak who engaged in maniacal binge drinking, nearly-suicidal motorcycle riding across the Japanese countryside, and though he wanted love, he was incapable of maintaining lasting relationships. Unlike Meissner, Kirst had Meisinger appear as one of the book's villains by portraying him as an especially-loathsome and stupid SS officer, who fully deserved to be deceived by Sorge. As part of Kirst's portrayal of Sorge as a tragic man on the brink and as victim led him to portray Sorge's spying for the Soviet Union by forces beyond his control. Kirst was more forceful in his condemnation of National Socialism than Meissner as his book maintained that the regime was so monstrously evil that an existential man forever on the brink of a mental breakdown like Sorge ended up spying for the Soviet Union as the lesser evil.
