They went to library to see some books about Slytherin, to solve 'someone will die in the end of October' mystery. Ron and Harry went to one part of library and start searching, when Hermione running quietly and putting out some thick books out. Ron and Harry put out one books each and start to reading it in one side of desk. "Look! Professor Snape is one of Slytherin, too!" Harry whispered to Ron, pointing his face - moving slowly. "You guys.. didn't.. even knew that?" Hermione asked. She was holding thick books, about 5~6. She put down some books and reading it. "So (Hermione read one book) you are more (Another) good at memoring things (Another)!" Ron shouted. "Well... How could you read three books when Ron was specking just 'So you are more..' thing?" Harry asked. "Then, you can't? It is easy! You can open book, and find what is inside the book, and when there isn't anything we want to find in here, putting down again, and pick one more, and find.. Isn't it?" Hermione answered, still reading. "Whou.. I never did that before, I never used that when I had only 1 munites to finish homework!" Ron shouted. "That's because you are foor. Now can't you guys move back to read?" Hermione answered. She finished reading 6th books and picking another. "I'm not foor, it is just you are smart!" Ron shouted angrily. "Ohh, that isn't important. Look here.." Hermione said, pointing one picture of a book name, 'Hogwart house - Slytherin'. It says, 'Last year, Grayhun's boy died at the end of November. And hogwart is thinking about Slytherin, because it is Slytherin's week.' "G.. Grayhun? What is for that?" Harry asked, confused. "You never know? There is a boy name 'Kevin Grayhun' in the school! Maybe, he is brother of the 'Grayhun's boy who died'." Hermione answered. "Is he Gryffindore?" Ron asked, surprising about Hermione's thinking. "Nope, he's Hufflepuff." Hermione answered back, "Now, don't ask me more things. We need to find Kevin Grayhun this time!" Hermione shouted as she opening library's door.
