The twins returned a while later, with a book. When it was set on the table, Percy could see that it was entitled Alchemists of Great Britain, and he recognized it as one of a set of books by the same historian which catalogued all of the significant figures of wizarding Britain from the beginning of recorded history. Alchemists was one of the ones he hadn't read, although he had on occasion skimmed Arithmancers and Political Leaders, respectively for class and out of personal curiosity.
