Given that many Doctor Who fans are working their way through their Doctor Who - The Collection: Season 21 blu-rays, we thought we'd have another book tie-in to the release.

The Scale of Injustice, by Gary Russell, introduced concepts such as the Silurian Triad with Icthar, Silurian battle cruisers and the Myrka, into Doctor Who, before Season 21.

We find out why Liz Shaw left UNIT, and how Mike Yates was promoted to captain - plus some events in the life of young Kate "Tiger" Lethbridge-Stewart!

We bring you a bonus episode on the creation of the new content for Doctor Who - The Collection: Season 21.

We're delighted to be joined by the brilliant broadcaster that is Dr Matthew Sweet, as we interview him about interviewing and interviewees.

It's rather meta, isn't it...?

With Season 21 now out on blu-ray, we take a look at another Doctor Who story that never was.

Today, our team of fantastic readers bring us The SCI, a four-part story by William Emms.

This was proposed by the writer of Galaxy 4 for Season 21, but was never developed - we bring you another lost story, courtesy of Richard Bignell.

It's a new Doctor Who - The Collection blu-ray release week, and, as ever, we've tied today's book club into it.

Today, we're looked at an adventure set during Season 21, and we speak to author Christopher Bulis about Imperial Moon.

It starts in a Scottish glen, with the Emperor Queen - and continues on the moon with the Fifth Doctor, Turlough and Kamelion.

A day later than planned (we had to mark the return of missing episodes!), we bring you the second part of our preview of the Doctor Who - The Collection: Season 21.

We're delighted to speak to Paul Scoones about writing (and re-writing!) the subtitles for five of the stories in this season, we learn about the new special effects on Warriors of the Deep with Chris Thompson, and finally, the brilliant Chris Chapman returns to discuss his involvement in three special features across the discs.

Phew! It's been a busy week - we hope you enjoy!

It's happened at long last - more missing episodes have been returned to the BBC!

Episodes one and three of The Daleks' Master Plan are back in the archives, after being found in the estate of a private film collector.

Join us as we share our excitement.

And you can find out more about the work of Film is Fabulous at their website - https://filmisfabulous.org.uk/

We're just days away from the 1980s being complete on Blu-ray as part of Doctor Who - The Collection.

To celebrate, we're looking at how some of the new content has been brought together, as well as restorations of the episodes themselves.

In this episode, we speak to the hero that is Mark Ayres, on his work to restore and remaster the audio, PDF king Richard Bignell shares some of the highlights of his researches for the ongoing production archive, while Derek Handley talks us through the photographic galleries.

Part two of this preview will arrive later this week.

We're heading into UFO territory, as Doctor Who meets The X Files!

Today's book club looks at David A McIntee's First Frontier, a novel which has become known for its shock twist in the years which have followed - the return and regeneration of the Anthony Ainley incarnation of the Master!

We feature some archive interviews with the author, which have been read for us by Dr John Bollan, plus the usual reviews and reactions.

We love our Doctor Who animations at the Power of 3.

So, we're turning the clock back to 2013, when The Ice Warriors was completed, thanks to the power of animation from Qurios Animation.

We speak to the team behind it, Chris Chapman and Niel Bushnell, about their work on it.

And Kenny and Dr John discuss their love of the adventure.

Doctor Who goes strange... stranger than ever!

Today, we're looking at Simon Messingham's sole entry into the canon of the New Adventures, Strange England. Simon joins us for a discussion on writing the book.

As ever, we feature the Doctor Who Magazine prelude and a couple of readings from later in the novel.
