Amnesia the dark descent part 1

I saw there was a hole in the wall I couldnt tear it down with my hands so I picked up a rock and threw it at the hole and it busted open. It led into a room with bookshelves. Then I suddenly heard a voice. "after the first one you must work quickly or it wont work." the voice said. I looked around I tried to get a gold colored book but it was stuck but then I realized that it was part of a secret passage. I quickly searched for gold colored books and pulled them and a bookshelf up against a wall opened and revealed a room. I picked up a key and a jar of oil for the lantern and left the room. I went out into the fireplace area and saw something walk into a door way I looked at the caved in door next to me and realized that thing noticed me and started to chase me I looked at it the out hanging deformed mouth, three claws on what used to be a left hand. I quickly dodged its attack and ran past it out the study.
