It all starts early in 1947 on the basis of the new SS-Swabia in Antarctica. The Nazis begin to install a drilling system to find a meteorite that crashed but did not disintegrate upon impact. At the same time in the Reich Chancellery in Berlin, Hitler had installed an artificial arm. The operation is performed perfectly and the Führer part in a massive demonstration at the stadium in Nuremberg tomorrow. The show is filmed by Leni Riefenstahl since his helicopter. Apart from the speeches of Hitler and Luftwaffe aircraft that their smoke draw a swastika in the sky, the highlight is the arrival of three aircraft SS: The Focke Wulf Triebflügel driven Rudel, Murnau and Hanna Reitsch. Then this tome 4 shows the number of air battles, talks about the reunion and Ingrid Walter Murnau but especially highlights the enormous influence of Himmler on the Führer what agasse deeply Goering, Speer, Goebbels and Admiral Donitz . Indeed empire SS Himmler and the Ahnenerbe (Nazi paranormal office) become more and more powerful. This volume 4 "The left hand of the Führer" is as I say in my title kind of transition between the first three volumes and those that follow. It marks a break. The designs of aircraft, U-Boot etc ... are superb but the characters are still not very similar. We made it and it is in all good holding. The end of the book about the meteorite makes me look forward to the future. Annexed we are entitled to a report by Jacques Bergier de Gaulle on the Ahnenerbe. In conclusion I will say that we are still dealing with excellent Uchronie who does not let himself. I hesitated to put only 4 stars because there are fewer shares and some delays but finally put 5 because the whole is nice. Adanson Marco.
