"The Treasure of Heaven: A Romance of Riches" by Marie Corelli is the story of an elderly millionaire who is disillusioned by all the trappings that come along with having wealth and living in society. On a whim, he decides to leave everything he has behind and go out "on the tramp," where he finds friendship and the secret to true happiness among the poorest of the poor who the others in his old world would never dream of befriending.
