The Life and Times of Thomas Schelling

His typist also worked for Agatha Christie and, during the time she was typing Schelling's works on conflict resolution, she was also typing Christie's classic play The Mousetrap.

That is from Robert Didge's The Strategist: The Life and Times of Thomas Schelling.  This book is fun, fun, fun.  Rather than trying to signal his abilities as a "serious biographer," Didge gives the reader insight into Schelling and his times.  Yes it does cover both his career as a military advisor and his personal life.  The new Milton Friedman biography was a bore, this is a delight.
