Notes

The Sign of Four is one of Sherlock Holmes's great adventures, a tale of 'an injured lady, half a million in treasure, a black cannibal, and a wooden-legged ruffian'. In the yellow fog of London, a young woman comes to 221b Baker Street with the strange tale of a missing father and the mysterious pearls she is sent anonymously each year. Holmes and Watson are soon swept up in an international puzzle of murder, millions and madness that could cost them their lives.146 p
