Set against the turbulent backdrop of armed conflict and a crippling depression, this book is far more than simply the story of an Australian – possibly the only Australian – to become a prisoner in two World Wars. Following the faintest of footprints, the authors embark on a journey to uncover the life and times of a man they barely knew – their father, Jack Probert, a knockabout, everyday Australian. In so doing, they reveal a dramatic tale of high adventure, perseverance, courage and ultimate tragedy.
