Jungle Comics #95

Prof. Northam, his daughter, Alice, and his assistant, Prof. Barton, discover valuable, ancient artifacts in the Gwaha country. They set up fake appearances by the Gwahas' gods to frighten the natives away, making it easier to seize the artifacts. An hallucinogenic drug, intended by Barton to drive Northram mad so that Barton could claim the discoveries as his alone, is smeared inside a pith helmet that is worn successively by Northram, Ann, and Barton. In his confused state, Barton detonates a load of dynamite, killing him and Northram.
