Brace yourselves, Doctor Who fans: Tom Baker’s Time Lord and companion Adric are set to reunite in a new series of audio adventures.

For the first time since 1981, the fourth incarnation of The Doctor and the boy genius played by Matthew Waterhouse will join forces for more stories set in parallel universe E-Space.

As part of the ninth series of Big Finish’s Fourth Doctor Adventures, the audio play producer will release two volumes of stories featuring the characters.

Originally from Alzarius, a planet existing in the parallel universe of E-Space (as opposed to our universe’s N-Space), Adric first became a companion of The Doctor in 1980’s State of Decay after sneaking aboard the Tardis.

Adric and The Doctor won’t be alone, however. The two will be joined by Time-Lady Romanadvoratrelundar II (Romana to us humans), played by Lalla Ward, while John Leeson will reprise his voice role as robo-canine companion K9.

While both K-9 and Romana have previously appeared in Big Finish adventures with the Fourth Doctor, the new stories will mark the first time Tom Baker and Matthew Waterhouse feature together in an audio drama.

“I’ve always found that when recording a Doctor Who on audio, it felt like coming home,” Waterhouse said about returning to work with Baker. “I absolutely loved it, and this [new series] is another development of that. I love the idea of E-Space with the Fourth Doctor, Romana, Adric and K9 travelling together.”

Explaining what listeners can expect from the new stories, producer David Richardson said: “We’re returning to another much-loved era in Series 9, as the E-Space trilogy gets a massive extension on audio and we explore strange and wonderful worlds in another universe with the genius team of the Doctor, Romana, Adric and K-9.

“It’s been such fun recreating the tone and high-concept style of that era, as the travellers begin the search for a CVE (Charged Vacuum Emboitment) which can take them (or at least most of them) home.”
