Wilkie Collins 
Moonstone 

Stolen from the forehead of a Hindu idol, the dazzling gem known as "The Moonstone" resurfaces at a birthday party in an English country home — with an enigmatic trio of watchful Brahmins hot on its trail. Laced with superstitions, suspicion, humor, and romance, this 1868 mystery draws readers into a compelling tale with twists and turns ranging from sleepwalking to experimentation with opium. The suspense and drama is heightened as the narrative passes from one colorful character to the next. Wilkie Collins‘ masterpiece is particularly distinguished by the appearance of Sergeant Cuff, a prototype of the English detective hero and the harbinger of a popular tradition of sleuthing.
