In 1957, just months after Fidel Castro had begun his revolutionary final assault on the Batista regime in Cuba, Greene played a small role in helping the Revolutionaries, as a secret courier transporting warm clothing for Castro's rebels hiding in the hills during the Cuban winter. Greene was said to have a fascination with strong Leaders, which may have accounted for his interest in Castro, whom he later met. After one visit Castro gave Greene a painting he had done, which hung in the living room of the French house where the author spent the last years of his life. Greene did later voice doubts about Castro's Cuba, telling a French interviewer in 1983, "I admire him for his courage and his efficiency, but I question his authoritarianism," adding: "All successful revolutions, however idealistic, probably betray themselves in time."
