To Sherlock Holmes, Lord Saint-Simon calls for help. A year ago, traveling around the USA, the lord met a charming girl, Miss Hetty Doran, the daughter of the richest gold owner on the entire Pacific coast and a violent character. The girl came to London and they got engaged. Before the wedding, Hetty was in a great mood, building plans for their life together. In the same mood she was at the wedding ceremony. Returning from the altar, the bride dropped a bouquet near the front bench, and a man, far from the circle of Lord St. Simon, gave it to her.
Lord Saint-Simon was scandalized by his former passion, the dancer Flora Miller, who wrote threatening letters to him after learning about the upcoming wedding. Anticipating this, the Lord placed policemen near the house.
The Lord withdraws, leaving the great detective to reflect on his problem, but then Inspector Leistred appears. In the pond was found a bag with the clothes of Lady Saint-Simon. In the pocket of the dress they found a note, in which it was written that Hetty should immediately leave. Instead of the signature were the initials F. HM Inspector does not doubt that this was written by Flora. But Holmes looks at the other side of the piece of paper, which turns out to be a scrap of bill from an expensive hotel.
Holmes goes on business, and soon a messenger arrives, which brings a luxurious dinner. After him come Holmes and Lord St. Simon. There is also a young couple – Mr. and Mrs. Multon. Mrs. Moulton runs up to Lord Saint-Simon and asks for his forgiveness.
The guests leave, and the great detective explains the course of his reasoning. The bride went to the crown voluntarily, but immediately after the wedding repented. What happened? It is clear that a man was involved, especially since someone gave her a bouquet. Having seen the expense of an expensive hotel, Holmes simply found a guest with the initials familiar to him on the note.
