Shanghai Knights

In 1887, Lord Nelson Rathbone leads a band of Boxers into the Forbidden City, killing the Keeper of the Imperial Seal of China and stealing the seal. With his dying breath, the Keeper gives his daughter, Chon Lin, a puzzle box for her brother, Sheriff Chon Wang. In Carson City, Nevada, Wang has captured an impressive array of fugitives. Wang receives the box and a letter from Lin telling him of their father's death and that she has tracked the murderer to London.
