A Study in Scarlet (Illustrated‪)‬

Accompanying Sherlock Holmes to an ill-omened house in south London, Dr 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 soon uncovers a trail of murder and lost love.
