33 Books With Shocking Plot Twists That Still Keep Us Up at Night

In Sarah Waters's Dickensian novel Fingersmith, we meet Sue Trinder, an orphan who was adopted in a London slum by a family of petty thieves. Hoping to repay them as she gets older, Sue is asked by one of the thieves, Gentleman, to get a job with a hapless gentlewoman so that he might eventually steal her inheritance. Sue initially agrees (happily), but as time goes on, she begins to regret her decision in big ways.
