Nathan Never #2

Plot

The Darkness in the Heart!" Cover by Art Adams. Nathan is assigned to go into the jungle; his mission: bring back Professor Korzeniowsky, the brilliant scientist who has spent half a decade in the jungle, working on a cure for a fatal disease that plagues the inhabitants of the area. Until recently, it was thought that the professor had disappeared, perhaps died. But recent rumors purport that the professor has joined up with the natives, something that the nearby pharmaceutical industry does not want to happen.
