For Doctor Who fans, the episode "Shada" piques geek curiosity like nothing else: It was meant to be an episode starring the much-loved fourth Doctor, Tom Baker, and written by the phenomenal Douglas Adams ... but was never aired because a BBC strike killed the production. Now our curiosity will be satisfied by current Doctor Who writer Gareth Roberts.
Roberts, who has written several Doctor Who episodes, including "The Shakespeare Code" and "The Lodger," as well as episodes for The Sarah Jane Adventures, will be turning "Shada" into a novel.
SFX wrote, "This will be the first time anyone other than Adams has novelised an Adams script."
In Roberts' novel, which is expected to be released by the end of March, we finally get to learn about the prison planet of Shada and the only Time Lord in the universe who knows its location—a Time Lord who has masqueraded as a professor at Cambridge University for centuries. And if the last part of that sentence seems familiar to you, it's because Adams re-used the plot of Shada in his book Dirk Gently's Holistic Detective Agency.
But in reality, our curiosity about "Shada" was satisfied years ago. Some of its footage made its way into "The Five Doctors." And according to Wikipedia, "In 1992, its recorded footage was released on video using linking narration by Tom Baker to complete the story."
Later, Shada became a Big Finish Productions audio play, starring the all-too-short-lived eighth Doctor, Paul McGann. You can find it here.
