In this final book of the Dave Hogarth space adventures trilogy, Dave returns to the scene of his previous exploits, a world many light-years from Earth. This time he is accompanying a glamorous and successful writer, ostensibly to advise on her new biographical book in which he will feature. As their relationship develops, Dave still finds time to pursue a theory with which he is obsessed - that the pharaohs of ancient Egypt were also space travellers and that they had visited this very planet. The final revelation on this comes in a startling climax.
