Amnesia: The Dark Descent - The Library version v1.01

You are Daniel. Your parents are away from town for a couple of days, so you are enjoying your peace and the quietness. You are reading a book, when suddenly a message drops from the books pages. Its from your uncle, and the ink is still wet. He has written it quickly and the first couple of words don't make any sense. Then the letter says: "Go to the library.. FAST!, you don't have much time!" Go to the library and try to find out what is going on. I guess you were going there anyway to put the book back.
