Who Do You Think You Are? - Season 12 - Eps 9: Mark Gatiss
Actor and writer Mark Gatiss has always had a love of storytelling and a passion for the ghastly and ghoulish but has always wondered where it comes from. So when he discovers that his mother's side of the family goes back five generations to the wilds of Northern Ireland, his imagination is awakened. Mark travels to Ireland, where he untangles a tale of rags to riches and finds out that his family were storytellers and (allegedly) vampire slayers!
