In this collection of short stories, Sherlock Holmes and his friend Dr. Watson go around London solving the queerest of cases. We see Holmes using his sharp, well-honed sense of observation coupled with his unerring instinct. It is an ability which utterly amazes and impresses Dr. Watson. In The Red-Headed League, we see them solving the purpose of a dubious organisation for red-headed men. In The Speckled Band, a young woman finds out how her twin sister was killed, the meaning behind her strange dying words and an escape from a life of great terror. The Boscombe Valley Mystery sees Holmes rescuing a falsely accused young man, while in The Blue Carbuncle he helps a trapped simpleton find justice.
