We were housed in a school in Katowice. Mr Frank was sitting by himself at a long table when I entered. (...) I told him, “I don’t know anything about the children; they were taken away.” And after a while, I told him about his wife. She had died in the bed beside me. Mr Frank didn’t move when I told him.’ Otto’s world collapsed. From that moment on, he had all his hopes pinned on Anne and Margot. Would they still be alive?
