What evidence does Mr. Greene provide for British connivance at Napoleon's escape from Elba, or for Talleyrand's masterminding the plot? Talleyrand was a thoroughly crooked operator, but prudent enough to see dangers in such a plan. Waterloo was anything but a walkover for the British and Prussian forces. Heaven knows that a lot of history instruction can render the most fascinating characters boring, but some overview of Talleyrand's earlier and later career, the history of the Congress of Vienna, the campaign that led to Waterloo, etc. etc. might enable to raise such questions. Is it really a gain to escape from the world of disconnected dry facts to a world of dubious theories?
