Ace finds herself separated from the Professor, marooned, blind and cared for by a mysterious stranger. How did she get there? Who is Dorsai? What secret is he hiding?
The Left Hand of Darkness is the first of two 'Ace Special' adventures which bring Sophie Aldred to the fore. Bill Baggs had been planning to feature Sophie's character alone and had commissioned BBV newcomer Mark Duncan to produce two adventures in which she would become separated from the Professor. When Sylvester McCoy (who makes guest appearances in these CDs) went on holiday, there was an ideal opportunity to produce these adventures.
