Bret meets an old "friend" on a riverboat heading to New Orleans, and gets swept up in a scheme to find the missing jewels of Napoleon during Mardi Gras.

A bank president in Denver hires Bret to find out the safecracker/gambler who plans to break into the vault. Bret discovers that an old family friend has a secret way into the vault. The friend is honest... but the people who might use him to steal the money, not so much.
