Spymaster was a children's game show invented by Forth Television that ran in the late 2080s. It was set in a film noir-style city, where a team of three players would play through a storyline interacting with actors and playing games to find clues.

It was one of the shows that Gwen Sorwen watched growing up - she was particularly fascinated with the final game where the players had to disarm slime bombs that had been planted throughout the city. One of her favourite parts was when a player had to enter one of a bank of phone boxes/gunge tanks and cut a wire, with a wrong choice activating the gunge above them.

The idea behind the show was based on UK game show Eyespy, which Iron-K saw at a similar age to Gwen.
