Adventure of the Copper Beeches [EPUB ebook] 

Violet Hunter has been offered a position as a governess by Jephro Rucastle, owner of the country estate the Copper Beaches, in Hampshire. She wants to have Sherlock Holmes opinion, as to whether or not she should accept the position. The pay is three times what she is used to but it comes with strange conditions, such as having to cut her long hair short. Yet her would-be-employer seems nice enough and finally, Violet takes the job. Holmes tells her to send him a telegram if she ever needs him. Two weeks later, a telegram comes in begging him to come to her. "The Adventure of the Cooper Beeches" is part of "The Adventures of Sherlock Holmes".-
