The Adventures of Sherlock HolmesChapter 3
Irene Adler Outwits Holmes
Holmes disguises himself to surveil Briony Lodge, witnesses Adler's sudden marriage to Godfrey Norton, and uses a fake fire to reveal the photo's hiding place. However, Adler flees to the Continent, leaving a taunting letter and her own photo, having seen through his disguise.
Outcome
Adler escapes with the incriminating photo; Holmes claims her photo as reward, dubbing her 'the woman' in rare admiration.
