Garner spent years recording monkey calls and then went to West Africa to watch chimpanzees and gorillas in the wild, famously from inside a cage of his own. He describes their habits, family life and intelligence, the sounds he believed formed a primitive speech, and his pet chimpanzees, among them Aaron, who watched over a sick companion.
