This illustration is from The Copper Beeches, one of the short stories in Arthur Conan Doyle's The Adventures of Sherlock Holmes, published in 1892. In this particular story, a young woman (Violet Hunter) asks Sherlock Holmes for advice about taking a job as a governess. The offered pay is incredibly- almost unbelievably- good, but comes with a number of weird requirements, including one that she cut her hair short. She ultimately decides to take the job, but Holmes has a bad feeling about the situation and asks her to contact him if anything happens. In this particular scene, Miss Hunter opens a drawer and finds a coil of long hair, the same colour as her own, and about the same length as hers before she cut it. It's all very unsettling.
