An impressively rollicking story that manages that rarest of feats; giving all three companions something to do that meaningfully contributes to the story. The companions' relationships with one another were well-developed as well. Richard Mace was a delightful rouge, the Tereleptils were thrillingly villainous, and the android... well, they can't all be winners. The Grim Reaper motif was a good idea, but I'm not sure it quite came across. Overall, a nicely made serial that kept up a reasonable pace throughout.
