Starting next month we’ve a trilogy of adventures starring Sylvester McCoy as the Seventh Doctor, Bonnie Langford as Melanie Bush and Sophie Aldred as Ace. First up is Red Planets and the TARDIS team are divided in space, and in time…

London, 2017. Except... it isn't.

Berlin, 1961. But it isn't that either. Not really. Not in the timeline the Doctor knows. Something is very wrong.

While Ace tries to save the life of a wounded British spy, Mel and the Doctor must get to grips with the modern day socialist Republic of Mokoshia. For Mel it feels strangely familiar and 'right', which makes the Doctor feel even more uneasy.

The second story in the trilogy to be released in September is The Dispossessed, and the Doctor must make the ultimate choice…

The Doctor, Ace and Mel are caught in a forever night. After crossing the threshold, a strange world awaits them.

An army of tortured souls. A lift that leads to an alien landscape. An alien warlord, left for dead, and willing to do anything to prolong his life… it’s all in a day’s work for the Doctor.

And the final chapter of the trilogy will be unveiled in October when the Doctor is reunited with Narvin (played by Seán Carlsen) and Dogbolter (from the Sixth Doctor tale The Maltese Penguin) in a battle for the entire universe in The Quantum Possibility Engine.

The Doctor and Ace are locked up. The TARDIS is gone. Things just couldn’t get worse, could they?

Of course they could. Things can always get worse – the new President of the Solar System, Josiah W Dogbolter, didn’t get where he is in life without learning that.

The Seventh Doctor also stars in November’s release, Warlock’s Cross, the finale of the UNIT trilogy which started with The Helliax Rift and followed with Hour of the Cybermen. With Tracey Childs returning as Klein (first seen in Main Range tale Colditz) in this final episode, the truth will out…

It’s time the truth was told. About UNIT. About the Cybermen invasion. About the so-called ‘Doctor’. About what happened all those years ago, at Warlock’s Cross. About the man they keep locked up in a cage, in a secret prison…

It’s time. Because UNIT scientific adviser Elizabeth Klein is going to help ensure the truth is brought to light.

Today’s the day… that UNIT falls.

But with endings come new beginnings and happy reunions. The Seventh Doctor meets Iris Wildthyme in December’s Main Range tale, Muse of Fire, and joining him are Ace, played by Sophie Aldred and Hex, played by Philip Olivier.

Oooh la la! It's been a long time coming, but the Doctor is about to be reunited with Iris Wildthyme! They're both in 1920s Paris and everyone's flocking to Iris's salon.

But wait...! What's that noise..? Thud thud thud...! It's the soft, approaching feet of a small and acerbic Art Critic Panda...!
