"I have in my pocket a manuscript," said Dr James Mortimer. "I observed it as you entered the room," said Holmes. "It is an old manuscript." "Early eighteenth century, unless it is a forgery." "How can you say that, sir?" "You have presented an inch or two of it to my examination all the time that you have been talking. It would be a poor expert who could not give the date of a document within a decade or so. You may possibly have read my little monograph upon the subject. I put that at 1730." "It appears to be a statement of some sort." "Well?" said he. "Do you not find it interesting?" "It does."
