Wilkie Collins 
The Woman in White [PDF ebook] 

“This is the story of what a Woman’s patience can endure, and what a Man’s resolution can achieve.” 
The first hundred pages of the book are gripping and intense. Wilkie Collins begins with an atmospheric mystery that is exciting and almost haunting.
The Woman in White is Wilkie Collins’ fifth published novel, written in 1859. It is considered to be among the first mystery novels and is widely regarded as one of the first (and finest) in the genre of 'sensation novels’.
Walter Hartright, a young art teacher, encounters and gives directions to a mysterious and distressed woman dressed entirely in white, lost in London; he is later informed by policemen that she has escaped from an asylum. Soon afterward, he travels to Limmeridge House in Cumberland, having been hired as a drawing master on the recommendation of his friend, Pesca, an Italian language master. The Limmeridge household comprises the invalid Frederick Fairlie and Walter’s students: Laura Fairlie, Mr. Fairlie’s niece, and Marian Halcombe, her devoted half-sister. Walter realises that Laura bears an astonishing resemblance to the woman in white, who is known to the household by the name of Anne Catherick, a mentally disabled child who formerly lived near Limmeridge and was devoted to Laura’s mother, who first dressed her in white.
Over the next few months, Walter and Laura fall in love, despite Laura’s betrothal to Sir Percival Glyde, Baronet. Upon realising this, Marian advises Walter to leave Limmeridge. Laura receives an anonymous letter warning her against marrying Glyde. Walter deduces that Anne has sent the letter and encounters her again in Cumberland; he becomes convinced that Glyde originally placed Anne in the asylum. Despite the misgivings of the family lawyer over the financial terms of the marriage settlement, which will give the entirety of Laura’s fortune to Glyde if she dies without leaving an heir, and Laura’s confession that she loves another man, Laura and Glyde marry in December 1849 and travel to Italy for six months. Concurrently, Walter joins an expedition to Honduras.
