Hello how may I help you? I need some help trying to remember a book. Okay what do you remember about this book? It was kind of about whale hunting. Okay. Do you remember anything else? It was quite old, I read it as a child around 45 years ago and I think it was old then. Okay. Was there a Captain Ahab? There was an old man but I don't remember that being his name. The only book I can think of that could match is Moby Dick Alot of people have insisted that's the book but it wasn't . In this one the old man helped a boy and girl build a raft. I'm sorry,, but my only match was Moby Dick.
