Agatha Christie's great-grandson has his own take on his great-grandmother's appearance on Doctor Who. The show first premiered in 1963 and tells the story of the timeless Doctor as he travels through time and space. In season 4 of the 2005 Doctor Who revival, David Tennant's Tenth Doctor took a trip back in time to meet Christie in "The Unicorn and the Wasp." He and his companion, Donna Noble (Catherine Tate), solved a mystery involving a gigantic shape-shifting wasp.
