As Ciel gave his usual order, Sebastian simply grinned. All day? please, he didn't need all day in order to gather the information. He simply bowed and said [+red "yes my lord."] As he closed the carriage door and then seemed to have disappeared. He started in the most obvious of places, checking all the local libraries to see if the book had been taken out, or stolen recently, coming up with nothing from there. He then decided to track the book in stores, learning of its price, and origin, and the type of people who generally purchased the book. He was given the answers he was looking for, allowing him to narrow down his search a bit more.
He then began by asking any and all of the local houses who owned the book, lying, and explaining to them he was with the yard, and was looking for any clues. He doubted the yard would ever go to this extent, so he knew he didn't have to worry about anyone from the yard ever finding out he did this. However, in all of his searches, no one was missing these pages, but they talked about seeing a child roaming the streets with a book that looked as old and warn as the pages that Sebastian was holding. This was news to him.
So he took to the streets and asked any of the street children if they knew anything, and they all knew of the boy, and said he was from out of town, and that he mentioned a house on a hill. Sebastian continued with his search, and went to this house to investigate. It looked like it had been empty for years now. All the doors were locked, but Sebastian figured Ciel would want to investigate this house.
Having learned all he had, he went back to the mansion just in time for the evening tea. He prepared the tea, and the small dessert he always added, and then headed to the earl's office to bring him the information, as well as his tea.
(Sorry for having been gone, I had work and school work to deal with. Made me a bit busy)
