Irene Adler Explained
Who Irene Adler is in the original stories and how adaptations changed her.
Tags: Irene Adler, A Scandal in Bohemia, Characters, Adaptations

The short answer
Irene Adler is important because she defeats Holmes in A Scandal in Bohemia. She is not important because she appears constantly; she is important because Holmes remembers her as “the woman” and because the case complicates his confidence.
Canon Irene vs adaptation Irene
Many adaptations turn Irene Adler into a major romantic, erotic, or criminal figure. The original story is more precise. Adler is intelligent, controlled, practical, and self-protective. She wins because she understands the situation quickly and acts before Holmes can fully control the game.
Why she matters
Adler matters because she changes how readers see Holmes. She does not out-deduce him in a laboratory sense; she outmanoeuvres him socially and emotionally. That is why the story still feels fresh.
