Hemingway Cutthroat — Michael Atkinson

A literary twist on what really happened while Hemingway was in '30s Spain, developing the story of For Whom the Bell Tolls and solving a murder with John dos Passos When one of Fascist Spain's political officials is found dead on a hillside, his own government colleagues suspiciously take little interest in finding the culprit. Hemingway, in the country as a journalist, can't let the murder go. Despite the other deaths everywhere around him--it is wartime, after all--he sets out to discover not just who killed the man but also the reason for the cover-up.
Written with wit and charm, Hemingway Cutthroat is equal parts classic espionage thriller and literary origin story for one of Papa's most famous novels.
