The Investigator is a 1973 British television pilot devised, produced and directed by Gerry Anderson, creator of Thunderbirds and other Supermarionation TV series of the 1960s. It centres on two American youths, John and Julie, who have been recruited by an extragalactic being called "the Investigator" to aid his self-appointed task of ridding Earth of evil and corruption. Miniaturised and given special knowledge and abilities, they take on Stavros Karanti, an unscrupulous businessman plotting to steal a priceless painting from a Maltese cathedral. Shane Rimmer and Sylvia Anderson voice John and Julie, who are represented by two-foot-tall (0.61 m) marionette puppets, while Charles Thake and Peter Borg appear as Karanti and his minion Christoph.
