Corporal Entwhistle's twin brother, Lord Entwhistle, is coming to the fort. In a mad scramble to impress him, Entwhistle proposes marriage to both Misty Moon and Lady Hammond, only to have his heart broken twice. Blackfly is also out to win Lady Hammond's favour, but even his temporary position as the acting Chief Factor is not enough to turn her head. Lord Entwhistle arrives in a pine box and Corporal Entwhistle is suddenly landed gentry.
