It is the 21st century, and you are Sherlock Holmes, the one and only famous consultant detectives in London with an unbeaten record. You have been informed that Irene Adler, an established dominatrix, is involved in an affair with a member of the British monarchy. She has obtained picture evidence, and is threatening to release them unless her nominated conditions are met, which would cause a scandal. You have been directly delegated the task by His Royal Highness to obtain those pictures, at all cost.
During the task, you have failed twice to infiltrate the household, due to her excellent stratagem. Upon the final attempt, you managed to succeed, but also realised 1) losing those pictures as leverage will immediately endanger her life and 2) you developed admiration and romantic feelings for this woman, which is something you have never experienced in your life.
