Series two reunited the late Mary Tamm as the first incarnation of Romana with the Doctor in seven adventures.

Series three and four saw Leela return to the TARDIS, in adventures that included the Cybermen, Exxilons, Sontarans, the Master and the Zygons.

And series five, released from January 2016, brought Lalla Ward as Romana II to the TARDIS for eight full-cast audiobooks set in the TV series' seventeenth season.

Two stories that were lost and only existed in script form were brought to life in Doctor Who – The Lost Stories: The Fourth Doctor Box Set. Available now at a special offer price of £25 on CD or £22 on download.

You can also get the Fourth Doctor Novel Adaptations on special offer. Get them individually at £7.50 on CD or £6 on download or in limited edition release format at £25 on CD or £20 on download.

The Fourth Doctor joins River Song in the forthcoming The Diary of River Song Series 4, due for release next month.

We’re also delighted to announce that another two seasons of the Fourth Doctor Adventures have been confirmed taking us up to 2021 – and we’re returning to E-Space in season nine! Lalla Ward comes back to the TARDIS, joined by John Leeson as K9 and Matthew Waterhouse as Adric.

And we also have the Comic Strip Adaptations releasing in March 2019. Based on the comic strips in Doctor Who Weekly Magazine (now Doctor Who Magazine), this box set features two adventures for Tom Baker’s Fourth Doctor - The Iron Legion and Star Beast.
