Season Three of Doctor Who: The Lost Stories continues this month with The Children of Seth.
The play finds the Doctor (Peter Davison), Tegan (Janet Fielding) and Nyssa (Sarah Sutton) following a mysterious message to a colony where the dangerous Byzan (Adrian Lukis) is vying to wrest control from the Autarch (David Warner). The cast also includes Honor Blackman, Vernon Dobtcheff and Matt Addis.
The Children of Seth was the third story written by Christopher Bailey, the writer behind the acclaimed Kinda and Snakedance. However it was abandoned and never made it to the screen – and so this full cast audio drama is a chance to experience what might have been.
