In any case, this page is our only possible starting point in re-creating the nature of the mysterious book, and it’s only from the nature of that book that we will be able to infer the nature of the murderer. For in every crime committed to possess an object, the nature of the object should give us an idea, however faint, of the nature of the assassin. If someone kills for a handful of gold, he will be a greedy person; if for a book, he will be anxious to keep for himself the secrets of that book. So we must find out what is said in the book we do not have.”
