Lost man at sea, lost novel recovered

"Gentleman Overboard" by Herbert Clyde Lewis published in 1937 slipped into forgotten books land as so many good books do (and shouldn't) until it was rescued. It's the story of Henry Preston Standish, who finds himself floating in the Pacific Ocean, sure the ship he fell off of will turn around and pick him up. It's ingenious tragicomedy with an objective. You've got to read it.
