How much does it cost for the Cuban government to pay off American spies? Nothing, according to the F.B.I. indictment of Kendall and Gwendolyn Myers, the former State Department employee and his wife accused of sending secrets to Havana over the past three decades. The pair, who are said to have once spent an evening with Fidel Castro in the Cuban capital, gave the secrets to the island government because of their belief in Cuba’s political vision. “You, speaking collectively, have been a really important part of our lives, and we have felt incomplete,” Kendall Myers told an undercover F.B.I. agent in April who was pretending to be a Cuban official. Today’s New York Times presents a picture of how the husband-and-wife team—one an expert in European history, the other a former senator’s aide—ended up dropping packages for handlers at local grocery stores and broadcasting secrets over short-wave radio.
