Read this excerpt from Anne Frank Remembered. I just sat there, frozen. I'd lost track of time. At some point the two workers from downstairs in the workplace came up to me and said that they were so sorry, that they hadn't known. Then Van Matto came and said something, and I saw that the Austrian had given him the keys that he had taken from me. I can't imagine where the time had gone. First, it had been eleven or twelve o'clock when the Dutch Nazi had come. Then it must have been about one-thirty when I'd heard the footsteps on the inner stairway. Then, suddenly, Elli was back, and Henk had arrived, and I realized that it
was five o'clock and the day had passed.
