A gripping tale of the air war - at a time when the deadliest skills were needed to survive. Length 127 thousand words June, 1943. Immense German and Russian armies face each other across the fortifications of the Kursk salient. Whoever wins the impending battle will win the war in the east; and the smallest factor could be the one that turns the tide. For the Prime Minister, that small factor could be a German Panzer general visiting France; if he can be eliminated then the Russians might stand a better chance of winning. But removing a high-ranking enemy officer in too obvious a manner could compromise ULTRA, the highly secret code-breaking operation that revealed the officer's location in the first place. Churchill has first to convince MI6 that the result will be worth the risk. With the outcome of a war hanging in the balance, what better plan than to give the mission to a handful of intruder pilots flying near obsolete aircraft?
