Now, the galactic entrepreneur Lyam Yce hopes, at last, to learn the reason why the ancient Teymahrians went extinct - by funding a huge archaeological dig. While the Doctor probes a strange sphere found by Yce's diggers, his companion, former Bletchley Park cryptographer Constance Clarke, agrees to help translate symbols written in the lost ancient language of the Teymahrians. And soon, they'll learn that ancient Teymah's secrets were best left buried deep beneath its shifting sands. Director Jamie Anderson is the son of Gerry Anderson, the producer behind such shows as Thunderbirds, UFO, Captain Scarlet and Terrahawks. His work influenced generations, and Jamie inherited this storytelling gene!
