Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel is "The Whispering Gorilla" from the master of wild science fiction, the "mad man," Don Wilcox. Even reporter Steven Carpenter didn't suspect the incredible future that lay in store for him. It had all started because he'd found out too much about a corrupt businessman named Swangler. And Steven Carpenter-being the crusading type-was never afraid to splash what he knew all over the big city newsstands. Then one day someone took a shot at him. So before he knew it, Carpenter was whisked off to the wilds of Africa for his own safety. Hiding on the remote jungle estate of a reclusive scientist, he continued to pound out his finger-pointing news stories. Then one evening a stranger showed up and lit a match, and soon Steven Carpenter was written into the annals of medical history. The second novel is "Return of the Whispering Gorilla" by veteran sci-fi author, David V. Reed. Steven Carpenter had a reputation as one of the best reporters in the business. Tough assignments were his forte, and he was known to be cool, calm, and fearless in the face of danger. Then a paid assassin brought his life to an abrupt end late one sultry African night... Yet he still lived A strange, fantastic experiment had seen to that. His brain was now inside the skull of a gorilla-and the gorilla could speak and reason. But the life he had once known was gone, and slowly but surely the blood that flowed through his veins began to take over, dulling his humanity and increasing the latent jungle instinct inside of him. And when a regiment of German soldiers turned up, they decided he was the perfect specimen for a new kind of Nazi soldier Soon the fate of those he cared for depended on Steven Carpenter holding onto his humanity for just a little while longer.
