chunk: The three construct a rude shelter and eke out an existence of near starvation for some weeks until Jane and William Clayton are surprised in the forest by a lion. Clayton loses Jane's respect by cowering in fear before the beast instead of defending her. But they are not attacked, and discover the lion dead, speared by an unknown hand. Their hidden savior is in fact Tarzan, who leaves without revealing himself, not realizing whom he was rescuing. Jane breaks off her engagement to William.
  Later Jane is kidnapped and taken to Opar by a party of the Oparian ape-men who were pursuing their escaped sacrifice, Tarzan. The ape man learns of her capture and tracks them, managing to save her from being sacrificed by La. La is crushed by Tarzan's spurning of her for Jane.
