"I think he's still in the day room，"the nurse said. "He likes to read at night...a darling old man."We went to the only room that had lights on， and there was a man reading a book. The director asked him if he had lost his wallet. Michael Goldstein looked up， felt his back pocket and then said，"Goodness， it is missing.""This kind gentleman found a wallet. Could it be yours？" The second he saw it， he smiled with relief."Yes，" he said， "that's it. Must have dropped it this afternoon. I want to give you a reward." "Oh， no thank you，" I said. "But I have to tell you something. I read the letter in the hope of finding out who owned the wallet."The smile on his face disappeared."You read that letter？" "Not only did I read it， I think I know where Hannah is."
