The Hitler Book: The Secret Dossier Prepared for Stalin from the Interrogations of Otto Guensche and Heinze Linge, Hitle

The original of Stalin's personal biography of Hitler is said to be held in President Putin's safe. The only other copy, made by Nikita Khrushchev, was deposited in Moscow Party archives under the code number 462A. It was there that two German historians found it and made it available to the public in full.
