The loss of the diamond opens the beginning of this adventure and events as related by Gabriel Betteredge, house-steward in the service of Julia, Lady Verinder. “ The Moonstone is a 19th-century British epistolary novel. It is an early modern example of the detective novel, and established many of the ground rules of the modern genre. Told from the perspective of 11different characters, tale of mystery and suspicion was considered the first modern English detective novel at its time of publication.” (Amazon).
