I was haunted by the fact that some more of Anne’s pages remained cast around on the floor in the hiding place. I was afraid to go back up there, as Silberbauer had already checked on me several times. He’d just pop his head in, saying, “I’m just making sure you haven’t gone.” I said nothing by way of reply. He’d seen what he wanted, that I hadn’t gone anywhere. He’d turn and leave.

I was afraid to go behind the bookcase again. It was very hard for me to look at the rooms with the people gone. I couldn’t face going back upstairs
