Rulah Jungle Goddess #26

Rulah works with an engineer named Pete to devise a plan to escape from the slave-holding kingdom and save a girl named Mirza. Using an underground stream and a telephone hookup, Rulah convinces Mirza's captors that they should be hanged at dawn, leading to a confrontation where Rulah must rescue both Mirza and Pete. In a backup story, Rulah faces a half-woman, half-ape creature called the Ape Woman of Antilla that has been terrorizing the peaceful Kraals, capturing their men into slavery, and Rulah must defeat this threat to save the jungle people.
