 As a mystery story, Stan Galloway concludes, “… any avid mystery reader will leave ‘Jungle Murders’ saying the author didn't play fair” because the scent clue is not transferable to the reader.Written in July 1939, and first published in "Blue Book" (April 1940).Tarzan, his monkey companion Nkima, Chief Muviro, and the Waziri warriors confront an American prize fighter, One-Punch Mullargan, who has come to Africa to hunt the wildlife, using a machine-gun.
