One day Martha receives an envelope in her mailbox. It’s from Boris. I love you, I’m full of you, I dream of you and us. Martha reads the sentence over and over again, deeply moved. “It was a sad, sad letter,” she will write many years later, “and a very loyal one (I still have it) and was his farewell I guess to me and to life. They say he was shot after this.” Martha will never suspect that the letter was written by a spy pretending to be Boris after Boris was shot.
