Shake and Blake - Episode 04

Ian Wilson fights through his flu to join Dave Probert for two more
episodes of Blake's 7. In "Mission to Destiny," Avon and Cally hunt
a murderer on a sabotaged ship while the Liberator embarks on a
mercy mission. And in "Duel," Blake and Travis are forced into a
fight to the death by ethereal beings who have clearly watched the
Star Trek episode "Arena." They also discuss religions based on The
Shawshank Redemption, a Blake's 7 version of The Benny Hill Show,
and Ian is greatly disturbed by a picture of a 1970s Doctor Who
monster. Which one? You'll have to listen to find out.
