One of the greatest real-life mysteries to feature in my novel Pyramid is the whereabouts of the ancient Egyptian sarcophagus of Menkaure, lost in a shipwreck in the 19th century as it was being transported to England. In both Pyramid and my previous novel Pharaoh, Jack Howard and his team dive deep into the Mediterranean in the search for the wreck and its treasures.
