Casca gets involved in the Boxer rebellion in China in 1899-1900 and fights on the Chinese side against the imperialist British oppressors. Well, that's the condensed version, but I found it by far the most hilarious of the Casca stories (the parade ground scene with the corpse on the flagpole and the bandit raid on the Chinese village being two scenes which had me in stitches) and if you can ignore the blatant anti-British bias that screams out at you this is an enjoyable yarn of Casca acting as a British undercover spy and ending up fighting against them. The Chinese water torture scene is very well done, too.
