Jack Nissenthal - The Man Who Knew Too Much.

What and where was Green Beach?

Why did one man land there in Canadian Army uniform when he was neither a Canadian nor a soldier, under conditions so strict that no one was told his name?

And what secret did he know so vital to the Allies that he travelled with a personal bodyguard of TEN sharpshooters whose orders wre to kill him rather than let him be captured?
