When American authors John Dos Passos and Ernest Hemingway went to Spain in 1937 to witness the Spanish Civil War firsthand, the devastation they encountered was far from impersonal: As Spain was unraveling thread by thread, so was the relationship between these two literary titans. They had arrived in Spain as comrades, leftist writers-in-arms. But a real-life literary mystery unfolded when Dos Passos’ friend José Robles—a Spanish-born Johns Hopkins professor—disappeared. Written from a novelist’s eye for detail, The Breaking Point is the story of two lives at the intersection of friendship and murder, of love and death, and of literature and history.
