This is one of the most interesting books of the summer. The first part is a critique of the Paris Peace Conference in the light of experience, with a full and intelligent if frankly subjective appraisal of its misfortunes, mistakes and merits. The lessons of all conferences are stressed as well as the lessons of the Paris Conference, and there are a series of personal characterizations which, when they are not too neat, are delightful. The second part of the book is made up of selections from the diary of the author, one of the British territorial experts at Paris, from the opening of the Conference up to the signature of the treaty with Germany. The book is very well written, as would be expected from the author of "Some People" and "Lord Carnock."
