Laws of the Jungle — Joseph Noble

Something is terribly wrong on Earth. An unprecedented menace is threatening the world's wildlife with extinction. In the jungles of the Congo, Agent Hemmingway Lawson (called Hemm by his friends) of the EarthLands Investigation Team (ELIT), hangs two hundred feet in the air and is about to witness a brutal crime. Hemm's cover is blown and he lands in the middle of a sinister scheme of world domination. The discovery takes the intrepid ELIT agent around the world, plunging him into one dangerous adventure after another. Good and evil forces press each other into deadlier circumstances. Until finally, Hemm finds himself in position to avenge the past and change the future.
