Cairo Jim and the Secret Sepulchre Sphinx

A fragment of an old diary puts Cairo Jim on the trail of a secret more stunning than all the Seven Wonders of the World put together. It's the find of the century - and Jim and his friends are the heroes of the hour. But behind the scenes lurks a manicured, prune-smelling, fez-wearing villain, with a devious plot to blast Jim's hard-earned reputation to pieces.
