Juju' by Murray Leinster is an entertaining adventure tale. It is the story of a vindictive gorilla, enslaved African natives and a small group of Britishers in Portuguese West Africa. The narrator and protagonist, Murray, a trader, is assigned to accompany Alicia Dalforth 150 miles into the jungle to the farm of Evan Graham to meet up with her fiancé Arthur Graham, Evan's older brother. Unfortunately, Evan is more disgraceful than most enslavers, and events quickly spiral out of control.
