1919. The eyes of the world are on the city of Paris where diplomats, politicians, spies and opportunists have gathered to discuss the fate of Germany in the aftermath of the cataclysm that was the First World War. In such circumstances, the last thing the British diplomatic community need is the untimely death of one of their delegation. So when Sir Henry Maxted falls from the roof of his mistress' apartment block in mysterious circumstances, their first instinct is to sanitize any unexplained aspects to his death.
But his son ex Royal Flying Corps ace, James 'Max' Maxted, has other ideas. He resolves to get to the bottom of Sir Henry's death - even if it does mean disturbing the impression of harmonious calm which the negotiating teams have worked so hard to maintain. In a city where nations are jostling for position at the crossroads of history and stakes are very high, it is difficult to tell who is a friend and who is a foe. And Max will soon discover how much he needs friends.
