Shmuel didn’t show up at the fence for two days after Bruno learned he’d be returning to Berlin. Bruno worried he wouldn’t get to see his friend again. But on the third day, Shmuel came. Bruno was glad to see his friend, but Shmuel looked more unhappy than usual. He told Bruno that his father had disappeared and that no one knew where he had gone. His father had left on work duty with other men, but none of them had returned.
