Lorenz was (understandably) one unhappy woman. She traveled to the United States, where the U.S. government quickly recruited her to return to Cuba and take her revenge. She was given two botulism-laced pills to use against her lover. But when she saw him again, Castro knew why she was there. He took his gun out of his holster, handed it to her, and said, “No one can kill me. No one. Ever.”
