The Penguin English Library edition. When Dr. John Watson takes rooms in Baker Street with amateur detective Sherlock Holmes, he has no idea that he is about to enter a shadowy world of criminality and violence. Accompanying Holmes to an ill-omened house in south London, Watson is startled to find a dead man whose face is contorted in a rictus of horror. There is no mark of violence on the body yet a single word is written on the wall in blood. Dr Watson is as baffled as the police, but Holmes's brilliant analytical skills soon uncover a trail of murder, revenge and lost love . . .
Problems involving a man with a twisted lip, a fabulous blue carbuncle and five orange pips tax Sherlock Holmes' intellect alongside some of his most famous cases, including A Scandal in Bohemia and The Red-Headed League.
