The Investigator centres on two 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 as puppets, while Charles Thake and Peter Borg appear as Karanti and his minion Christoph.
Written by Sylvia from a story by Rimmer, it was filmed on location in Malta between the production of The Protectors and a planned second series of UFO (which would later be made as Space: 1999).
The puppet sized Car & Boat from the pilot episode are in the Sylvia Anderson Collection and are available for coventions & displays.
