Read the excerpt from The Diary of Anne Frank. MR. KRALER

That's the man. A couple of weeks ago, when I was in the storeroom, he closed the door and asked me . . . how's Mr. Frank? What do you hear from Mr. Frank? I told him I only knew there was a rumor that you were in Switzerland. He said he'd heard that rumor too, but he thought I might know something more. I didn't pay any attention to it . . . but then a thing happened yesterday . . . He'd brought some invoices to the office for me to sign. As I was going through them, I looked up. He was standing staring at the bookcase . . . your bookcase. He said he thought he remembered a door there . . . Wasn't there a door there that used to go up to the loft? Then he told me he wanted more money. Twenty guilders more a week.
