The book is a detailed chronicle of the Paris Peace Conference, where the Allied Powers gathered to negotiate the terms of peace with the Central Powers. It covers the complex political dynamics, the role of key figures such as Woodrow Wilson, David Lloyd George, and Georges Clemenceau, and the challenges faced in drafting the Treaty of Versailles. Dillon's account is particularly critical of the secretive and often manipulative nature of the negotiations, and he highlights the conflicting interests and ambitions of the participating nations.
