By the author of Clemenceau, this is an account of the political, constitutional and social life of Europe's capital cities in the year leading up Waterloo. It explores the dramatic events of the Hundred Days through the perspectives of three different European cities - London, old revolutionary Paris and baroque Vienna - using Castlereagh and his quest for peace as a central thread. It aims to explain the machinations of country against country, their different political and ethical viewpoints, and how the decisions and emotions of men and women helped form a fragile Europe in a time of flux.
