The Woman Who Smashed Codes by Jason Fagone

In 1916, Elizebeth Smith is hired by the eccentric George Fabyan to prove that Francis Bacon was responsible for the work assigned to William Shakespeare.  At Fabyan's Riverbank compound she meets William Freidman.  While she searches through the absurd clues to the Bacon/Shakespeare conundrum, she reveals herself to be a talented puzzle solver much like William.  Otherwise an unlikely pair, they fall in love and for the next 50 years, become the most significant code breakers in America.  WWll, the Enigma, the Cold War, the beginnings of the NSA, Hoover - name the event or the individual connected with espionage from WWl to the 1960's and they were somehow connected.  The auditorium at Fort Meade was named after William but Elizebeth's contribution has been largely ignored.  This well researched book corrects that situation.  Intriguing history and a worthy subject but I wish it was clearer how they did it. Still classified?
