When Rachel Verinder’s birthday present — the Moonstone, a large Indian diamond — is stolen at her party, suspicion and the diamond’s mysterious curse seem set to ruin everyone and everything she loves. Only Sergeant Cuff’s famous detective skills offer any hope of peace and a future for them all. The intricate plot and modern technique of multiple narrators made Wilkie Collin’s 1868 work a huge success in the Victorian sensation genre. With a reconstruction of the crime, red herrings and a ‘locked-room’ puzzle, The Moonstone was also a major precursor of the modern mystery novel.
