On breaking open the Berlin Bunker on 2 May 1945, Soviet troops captured two of Adolf Hitler's closest associates: his personal valet, Heinz Linge, and his SS adjutant, Otto Guensche. The two men had just disposed of the bodies of Hitler and Eva Braun.

On Stalin's orders they were questioned for two years, to produce this astonishing fly-on-the wall account of all they saw in Hitler's headquarters, where they had worked since 1933. It has been held in top-level Russian archives since 1949.

The book contains remarkable insight into Hitler's daily life before and during the Second World War. Chilling, revealing and compellingly readable, it is one of the most authentic sources of information in existence on the history of the Third Reich, unique in the circumstances of its compilation and its closeness in time to the events described.
