Episode three of the third Sapphire & Steel story introduces another one of the agents. He’s called Silver and he’s played by David Collings. Everybody likes Silver. He’s kind of twinkling, clever, a little fey, and much, much nicer than Steel. He’s a technician, and boasts that there isn’t a machine – past, present, or future – that he cannot repair.
Our son spotted a pattern. He noticed that the odd-numbered stories introduce new members of Sapphire and Steel’s agency. There’s another reason to be annoyed that the program ended when it did. Who knows who we might have met in stories seven and nine? Stupid television companies.
