The Adventure of the Copper Beeches – AudioEbook.
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 £100 a year, later increased to £120 when Miss Hunter baulks at having to cut her long hair short. 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.
