The Woman in White 

Often considered one of the first mystery novels, The Woman In White follows protagonist Walter Hartright, an art teacher, as he has a mysterious late night encounter on a London street with a lost woman, dressed all in white, who he later finds out had escaped from an asylum. The figure of this woman and the words they exchanged during their meeting come to haunt Walter, even as he accepts a job at Limmeridge House outside of London to instruct heiress Laura Farlie in art. Walter soon recognizes the astonishing resemblance between Laura and The Woman In White, and finds out that the mystery woman also used to live near Limmeridge and has connections to the Farlie family. A tragic, haunting tale about mistaken identities, unbelievable selfishness and cruelty, bust also true love and persevering friendship. A true classic.
