On 10th May 1941, an extraordinary event occurred. In many ways it was the most bizarre and inexplicable episode of the Second World War and it has never been fully explained - until now. On that spring day, Rudolf Hess, Adolf Hitler's deputy, took off from Augsberg airfield in a Messerschmitt BF110. His target was a location in Scotland and on the same evening, alone and in darkness, Hess baled out and floated down to earth - and imprisonment for the rest of his life. The generally accepted view is that Hess was on a desperate lone mission to broker peace with Britain. But what if he wasn't acting alone? What if he was enticed there by British Intelligence? What if he was lured with the full knowledge of Churchill and went with Hitler's approval? This book sets out to answer those questions and to tie up the loose ends of this bizarre historical mystery.
