Michael Reynolds discovered the truth about Hemingway's activities during the war years, which included running a counterintelligence operation in Havana. The postwar period was the most productive of Hemingway's writing life, when he authored the Pulitzer Prize-winning <em>The Old Man and the Sea</em> and received the Nobel Prize. Even as Hemingway graced the cover of <em>Life</em> magazine, his physical and mental health deteriorated while his public image as hunter and sportsman continued to demand the strenuous life. In 1961 he committed suicide, leaving behind the stuff of which American myths are made.
