This story involved both Mycroft and Sherlock Holmes and it was different because each brother was solving a different crime, but in the end their combined clues led to a marketer's death. Sherlock had help from Mycroft's Chinese valet and Mycroft had Dr. Douglas. There were 11 murder victims one of whom was related to Queen Victoria. The second mystery was about a kidnapped Chinese man who was engaged to girl who Mycroft had fallen in love with. I was disappointed with the endings to both mysteries, since I don't think justice was done; but in real life it rarely is.
