What is written In the news papers ?

Someone has sent a letter to his hotel, constructed of printed words cut from somewhere and then pasted. It reads: "As you value your life or your reason keep away from the moor" (167). Only the word "moor" has been hand-written. The mystery is all the more disconcerting since nobody knew which hotel Sir Henry planned to stay at.

From the typescript, Holmes quickly discerns not only which newspaper the words were taken from, but also from which article, and in fact determines that the words were cut with nail scissors.
