Adventures in a Pocket Universe (series)

Adventures in a Pocket Universe were two audio dramas released by BBV Productions under their Audio Adventures in time and Space banner.

These two audio dramas, The Choice and The Search, featured John Leeson as K9 and Lalla Ward as 'The Mistress' (thought heavily implied to be Romana II). Lalla Ward's character was only ever known or referred to as 'The Mistress' (which was how K-9 originally referred to her) as the character of Romana was governed by the BBC license.
