[Michlib-l] Hello fellow librarians

I have a stumper. Patron came in looking for a book and i have no ideas. She says that it is a black cover with a red diamond on the front. It is about a man that has been in prison and he escapes. He crawled across the desert and on the way finds a bunch of diamonds. They were all inherited by his family. The story is told by one of his twin sisters. HELP!! It does not ring any bells in my belfry. A fiction work. Thank you. Diane Willick Ruth Hughes Memorial District Library dwillick@ruthhughes.org
