Serpent Crest

Serpent Crest is an audio play in five episodes based on the long-running British science fiction television series Doctor Who. It is written by Paul Magrs, and stars Tom Baker as the Fourth Doctor and Richard Franklin as Captain Mike Yates. It was released on five CDs by BBC Audiobooks between September and December 2011 and is a sequel to 2009's Hornets' Nest and 2010's Demon Quest. They feature multiple actors, but four of the episodes contain some degree of narration by different characters, the exception being the first episode, Tsar Wars.
