The Adventures of Sherlock Holmes: A Scandal in Bohemia (p177-200)

These few pages are about a Germain man named Count Von Kramm. This is his fake name and when he went to Holmes he found out that his real name was Wilhelm Gottsreich Sigismond von Ormstein and he is an heir to becoming King of Bohemia. He tells Holmes that he is engaged with a princess named Clotilde Lotman von Saxe-Meningen but is having relationships with a woman named Irene Adler. She is threatening to reveal what is happening with a photo she has.
So Holmes follows her into a church the next day and finds that Irene was getting married to someone else. So then Watson faked a fire and saw that Irene went to a place in her sitting room and because they now knew where the picture was he then again yelled that it was a false alarm. The next day they went to her house again and could not find the picture and also found out that her husband was not there. They then found a letter saying that she loves her new husband and will not harass the Wilhelm anymore.
