The Doctor headed to his library and walked the rows like a man on a mission. He stopped and turned, heading down an aisle. About halfway down he stopped and ran his fingers over the spines of the many books lining the shelves. He stopped, plucked a rather thick leather bound book and opened it quickly scanning the index. He closed the book and held it by his side as he turned and quickly headed back out towards his room. Book safely on his bed, he then headed to meet Rose in the kitchen just as she was finishing the tea.
