One of the best Tarzan adventures, in which Tarzan vows vengeance upon all Germans after German soldiers have invaded his African estate in his absence and killed Jane and his Waziri. Includes Tarzan's memorable trek across a great desert and the best passage in Burroughs' body of work (pg 127). A memorable story which expands upon Tarzan's character in the belief that Jane is dead. ( )

With the speed of the great apes, Tarzan rushed through the jungle toward his home and family. But he was already too late. The marauders had been there before him. His farm was in shambles and no on was left alive. Silently, he swore his terrible vengeance against those who had done this monstrous deed. Then he set out grimly to track them... through warring armies...across a vast desert that no man had ever crossed...and to a strange valley where only mad men lived.
