This is not just the obvious exciting adventure of escape and evasion in enemy territory but also a mystery, told with detective-novel skill, of a son's slow unveiling of the biggest story of his father's life and the extraordinary, daily and nightly, kindness of strangers that saved a PoW on the run. The hero being Field Marshal Montgomery's stepson, the book also sheds light on the private life of Monty whose harsh and even nasty professional demeanour masked a fondness for the simple and silly delights of being with children: this is a man who wept, in uniform, at his wife's funeral.
