The narrator of this extraordinary tale is a man  in search for truth. He answers an ad in a local  newspaper from a teacher looking for serious  pupils, only to find himself alone in an abandoned  office with a full-grown gorilla who is nibbling  delicately on a slender branch. "You are the  teacher?" he asks incredulously. "I am  the teacher," the gorilla replies. Ishmael is a creature of immense wisdom and he has a story  to tell, one that no other human being ever heard.
