Key takeaways
- Irene Adler (SCAN) is the only person to have outwitted Holmes, earning the epithet “the Woman.” She appears in only this one story but looms large in the Canon’s mythology.
- The five orange pips (FIVE) is one of very few stories where Holmes fails to save his client — the client dies before Holmes can act.
- SPEC is widely cited by readers as the most popular Holmes story; it establishes the locked-room mystery template and contains some of Holmes’s most theatrical behaviour.
- TWIS introduces the opium-den setting and the question of Holmes’s own drug use, developed more fully in The Sign of the Four.
- COPP ends the collection with a case where Holmes’s delay contributes to violence — a self-critical note.
