Coming in April 2016, Blake's 7: The Liberator Chronicles Volume 12 is a new collection of audio stories from the legendary Terry Nation's science-fiction series – and we're delighted to reveal details of the set's first story.

Corners of the Mind by Andy Lane will see Avon (Paul Darrow) trapped in a labyrinth of puzzles; one which is gradually stealing his memories. He will need all of his wits if he is to survive – and the help of his crew mate Cally (Jan Chappell).

'Corners of the Mind pushes Avon to the fore - and the limit,' says producer Cavan Scott. 'Andy wanted to tackle Avon’s logical mind, forcing our unwilling rebel to use that magnificent brain that he’s so proud of… even if it kills him in the process.'

Two further adventures will also be included in the new box-set – which features a return appearance from David Warner as Vila’s estranged father.

In celebration of the new announcement, we're also pleased to reveal a new trailer for the series – where an old friend gives us a very welcome message!

Blake's 7: The Liberator Chronicles Volume 12 can be pre-ordered today from the Big Finish website for only £25 on CD or £20 to to download. Eleven earlier volumes are still available to order.

You can enjoy join the Liberator crew in two series of Blake's 7: The Classic Audio Adventures – with each title from Series 1 and the special release Blake's 7: Warship available at only £5 each.
