Peter Potter knows his invention will be of immense value to the nation. But only if it is used wisely and denied to any potential aggressor state or organisation. He must gain access to the highest echelons of the establishment whilst still keeping his invention under wraps. How can he convince those in power of the marvellous potential of ROVER and at the same time prevent its secrets from leaking out? This dramatic story of an amazing invention has its roots in the darkest chapter of the Second World War and moves forward to an alternate present day.
