Edgar Rice Burroughs' Tarzan #131

In "The Canyon of No Return," Tarzan finds himself entangled in a mystery deep within the African jungle, where the enigmatic Aba-Zulu elder Gathongo uses a truth serum on a hypnotic stranger. The stranger's cryptic revelation about the Tungelus—how they prepare their own food—unravels a deeper intrigue, leading to a tense stand-off when the stranger tries to flee, only to be halted by the loyal Tavane. Written by Gaylord Du Bois and illustrated by Russ Manning, this 1962 Dell adventure captures the classic jungle thrills of Tarzan’s world, with George Wilson’s dynamic cover adding to the sense of danger lurking just beyond the next bend.
