The Daleks also play a major role in the first produced stageplay to feature the Doctor. Doctor Who and the Daleks in the Seven Keys to Doomsday was written by Terrance Dicks and directed by Mick Hughes and ran at London's Adelphi Theatre over the 1974-75 Christmas season and was expected to tour England until April 1975. However the tour was cancelled at the 11th hour. Trevor Martin played an alternate version of the Fourth Doctor in this play, which takes place immediately after the Third Doctor's regeneration in Planet of the Spiders (the play was staged before Tom Baker's official debut as the Fourth Doctor in early 1975 although Baker had appeared at the close of Planet of the Spiders). The play co-starred former Doctor Who companion Wendy Padbury (playing a different character named Jenny). Also in the cast was Simon Jones as the "Master of Karn", several years before he worked with Doctor Who writer Douglas Adams on The Hitchhiker's Guide to the Galaxy. The play was not well-attended by audiences as it debuted during an upswing of IRA violence in London.Peel, John and Terry Nation: (1988). The Official Doctor Who & the Daleks Book.
