The Moonstone, a priceless Indian diamond which had been brought to England as spoils of war, is given to Rachel Verrinder on her eighteenth birthday. That very night, the stone is stolen. Suspicion then falls on a hunchbacked housemaid, on Rachel's cousin Franklin Blake, on a troupe of mysterious Indian jugglers, and on Rachel herself. The phlegmatic Sergeant Cuff is called in, and with the help of Betteredge, the Robinson Crusoe-reading loquacious steward, the mystery of the missing stone is ingeniously solved.
Wilkie (William) Collins (1824-89) was a hugely successful and popular crime, mystery and suspense writer. He wrote the first full-length detective novels in English and set a mould for the genre as shown in The Moonstone and "The Woman in White."
