This episode is one of the few that actually addresses the odd powers of the Mysterons in a neat way. This time, Captain Black kills an air force major and duplicates him, but the major’s body is found by a pair of doctors with an experimental resuscitator and bring him back to life. Unfortunately, Tony Barwick’s story doesn’t get into what that might mean for the duplicate – he doesn’t short-circuit or melt or anything – and it instead concludes that they can both be alive for a short time, and Spectrum can try to use the real major to get a line on Black.
At least three of the characters in this story are played by puppets that were used in earlier episodes. I swear, some of these puppets got more screen time than the minor members of Spectrum. I had wondered aloud whether Anderson might have actually shelled out for some new “faces” on his later productions, but apparently not. I’ve enjoyed looking over a Captain Scarlet fan site called Spectrum Headquarters for background to this blog, and noticed that some of the lesser-used Spectrum characters, like Captain Ochre and Doctor Fawn, had their puppets reused in Anderson’s next two series, Joe 90 and The Secret Service, as the sort of one-off characters like one of the doctors and his nurse in this one. Even the puppet of Lt. Green, who appeared in every episode of Scarlet, was reused as a background character in those other shows.
