There were no bullfights in 1937 Madrid, just bombs, freedom fighters, journalists, and plenty of corpses. Ernest Hemingway, covering the Spanish Civil War for the American press, came looking for stories and danger, and found something else: a friend murdered amid the ruins.             With a new novel stirring in his head and his veins pumping with booze, Hemingway sets out to find who killed José Robles Pazos, a bureaucrat in the Popular Front, and who's covering it up. There is, after all, nothing like risking death in a war zone if it means living fast, nailing the bastards, and avoiding a deadline. With the writer John Dos Passos at his side, Hemingway wades into the darkness, discovering that his old WWI buddy is no mere casualty of war---but victim of something far more terrible.             Boisterous, bare knuckled, and stewed to the gills,Hemingway Cutthroatcaptures the writer at the height of his career and in a Europe teetering on untold cataclysm, struggling to find out not just for whom, butwhy the bell tolled.
