What Happens, Part by Part (Contains Spoilers)
The cursed diamond
During the 1799 siege of Seringapatam, a British officer, John Herncastle, steals the Moonstone from a sacred statue, killing its guards. Years later, he leaves it in his will to his niece Rachel, perhaps out of spite. Three Indian men have been watching for it ever since.
The birthday night
Franklin Blake brings the diamond to Rachel's country house in Yorkshire for her birthday. That night, it disappears from her cabinet. Rachel refuses to cooperate with the investigation and coldly rejects Franklin, as if she knows something.
Sergeant Cuff
The famous detective Sergeant Cuff investigates. He suspects Rachel and a housemaid, Rosanna Spearman, who had a criminal past and loved Franklin. Rosanna drowns herself in the Shivering Sand. Cuff's theory makes the family angry, and he is dismissed.
Many voices
Over the following year, other narrators continue the story, including a pious relative, a lawyer and Franklin himself. Franklin discovers a letter from Rosanna, with a nightgown stained with paint, proving that he himself took the diamond, though he has no memory of it.
The solution
A doctor's assistant, Ezra Jennings, realizes that Franklin was secretly given opium that night and took the diamond while in a trance to protect it. A re-enactment confirms it. Franklin gave the diamond to Godfrey Ablewhite, who secretly needed money and pawned it. Godfrey is found murdered by the three Indians, who return the Moonstone to its shrine in India. Franklin and Rachel marry.
