Wilkie Collins 
The Woman in White 

Considered one of the first mystery novels, ‚The Woman in White‘ is Wilkie Collins’s epistolary novel that tells the tale of Walter Hartright, who encounters a woman all dressed in white on a moonlit road in Hampstead. Hartright helps the woman to find her way back to London. The woman warns him against an unnamed baronet and when they part he discovers that she may have escaped from an asylum. Hartright travels to Cumberland where he takes up as an art tutor and meets two half-sisters, Laura Fairlie and Marian Halcombe, who are somehow entangled with this mysterious ‚woman in white‘.
