The Adventure of the Copper Beeches

"The Adventure of the Copper Beeches", one of the 56 short Sherlock Holmes stories written by British author Sir Arthur Conan Doyle, is the last of the twelve collected in The Adventures of Sherlock Holmes. It was first published in Strand Magazine in June 1892.
Violet Hunter visits Holmes, asking whether she should accept a job as governess; a job with very strange conditions. She is enticed by the phenomenal salary which, as originally offered, is L100 a year, later increased to L120 when Miss Hunter baulks at having to cut her long hair short (her previous position paid L48 a year). This is only one of many peculiar provisos to which she must agree. The employer, Jephro Rucastle, seems pleasant enough, yet Miss Hunter obviously has her suspicions.
