On board ship, Bullen rescues Tom the cabin boy from a mad crewmember. At home Sarah introduces her friend, a retired naval captain called Arbuthnot Dampier (played by Patrick Troughton, the second Doctor Who) to her family. Samuel disapproves. Dampier says that he inherited an estate and owns a steam yacht called "Amazon" (the yacht used in filming was, in fact, the ex-steam yacht "Amazon"). James says that at least he has an estate so he can't be after Sarah's money which was all that worried him.
