Doctor Who: The Lady of Mercia

Written by Paul Magrs, directed by Ken Bentley

Starring Peter Davison, Janet Fielding, Mark Strickson and Sarah Sutton

The TARDIS brings the Doctor, Tegan, Turlough and Nyssa to the University of Frodsham, close to where the warrior queen Æthelfrid fought a desperate and bloody rearguard action against the savage Danes. Over a thousand years later, in 1983, battle is still being raged, with student activists taking on savage funding cuts… and disrupting a conference about Æthelfrid convened by history professor John Bleak.

Meanwhile, over in the Physics Department, Dr Philippa Stone is working night and day on a top-secret project – but can her theoretical time machine really be the solution to the university's problems?

Present and past are about to collide – and the results, as the TARDIS crew is about to discover, will be far from academic!

Doctor Who - The Companion Chronicles: The Apocalypse Mirror

Written by Eddie Robson, directed by Lisa Bowerman

The TARDIS lands in the city of Tromesis on Earth – but it’s a world far from the one that the Doctor, Jamie and Zoe recognize.

The buildings are ruined, the streets deserted. And against the devastation they see a ghostly mirror image of another place – the city as it was before disaster hit.

People vanish here, and huge metal birds attack from the sky.

Can the Doctor find the future, in a place that doesn’t have one?

Doctor Who: Phantoms of the Deep

Written by Jonathan Morris, directed by Ken Bentley

Starring Tom Baker, Louise Jameson and John Leeson, with Alice Krige

On their mission to explore the Mariana Trench at the very bottom of the ocean, the deepest and most inhospitable place on Earth, the crew of the deep sea vehicle Erebus make an unusual and startling discovery.

A battered blue police box.

As the Doctor, Romana and K9 join them on their journey, the submariners soon discover that the TARDIS is not the only unusual find lurking on the sea floor.

Super-intelligent squid, long-lost submarines and their miraculous occupants are only the start of their troubles. The Goblins are coming. And they won't let anyone out alive.

Downloads of all three titles are available now, and CDs will be posted out from today.
