Sophie: Irene Adler. Only woman smarter than Sherlock Holmes.
Referencing Sir Arthur Conan Doyle's short story "A Scandal in Bohemia" (July 1891). Irene is an American adventurer who becomes romantically involved with the married King of Bohemia, Wilhelm Gottsreich Sigismond von Ormstein. She outwits Holmes, who is hired to retrieve an incriminating photo from her, but turns the photo over to him anyway. She is mentioned briefly in other Holmes stories, typically when the Great Detective acknowledges her superior talents. Irene has appeared in many derivative works, and featured in a series of mystery novels written by Carole Nelson Douglas.
