The Black Guardian is back! The Doctor’s old enemy, who appeared in the television series in 1979 and 1983, is returning for the forthcoming "Key 2 Time" season of audio adventures.

This character, originally played by Valentine Dyall, features in the second story, "The Destroyer of Delights", and this time will be played by David Troughton, son of the Second Doctor, Patrick Troughton, who also recently appeared in the television series story "Midnight" and in "Cuddlesome" the special story given away free with issue 393 of The Doctor Who Magazine.

‘David was a delight to work with on "Cuddlesome"’, says "Key 2 Time" Producer David Richardson, ‘and when read Jonathan Clements’ script for "The Destroyer of Delights" I instinctively felt that he’d be ideal for a character of such great presence and menace. Fortunately Big Finish’s executive producer, Jason Haigh-Ellery, and the director, Lisa Bowerman, absolutely agreed, and David embraced the opportunity to play a Doctor Who icon’.

The "The Destroyer of Delights" is due to be relased in February 2009.

Big Finish Productions has also revealed that the "Key 2 Time" season opening story "The Judgement of Isskar" guest-stars Raquel Cassidy, from televisions "Lead Balloon", "Party Animals" and "Teachers", as the Lady Mesca. The climactic story "The Chaos Pool", which is written by Peter Anghelides, also sees the return of Lalla Ward to the audio series.
