Prague, 1942. Two men must kill the third. This is Operation Anthropoid: two Czechoslovak saboteurs sent from London are tasked with killing Reinhard Heydrich, the Gestapo chief, head of the Nazi intelligence services, "the most dangerous man in the Third Reich," who planned the "final solution" to the Jews. Heydrich was Himmler's right hand man. The SS said: "HHhH" - "Himmlers Hirn heist Heydrich", ie "Himmler's head is called Heydrich". All the characters in this book really existed. All the events depicted in it are true. However, behind the scenes of preparation for the assassination is another war, one that is between artistic fiction and historical reality. And yet, the story must be told to the end...
