When Sherlock is asked to find the son of a nobleman, he enlists William's help to infiltrate the club where the nobleman lives. They get to the bottom of the case, but a hostage taker, a "game enthusiast", forces them to take part in a game of Russian roulette. In four short stories, Bond teaches acting to the Whitechapel troupe, Jack is put to the test when the three brothers become his apprentices, and Sherlock is introduced to a strange case on holiday by Mycroft!
