Dossier On Dumetrius

… the story of a document now gathering dust in a silent room.
Dossier on Dumetrius is one of Grace Gibson’s best-loved and most successful ‘spy’ serials. It introduced Major Gregory Keen of MI5, the forerunner to James Bond. It is the first of five stories featuring Keen as the central character.
The story is set in Post War London and tells of the search for missing Nazi loot which was brought into England by a mysterious, vicious criminal Dumetrius, his gorgeous girlfriend Hedy Bergner and Yottie Bleem, a Butcher who thinks murder is fun.
Of course, Keen falls in love with Hedy and only learns her true feelings when the story reaches its highly exciting climax.
An interesting and distinctive feature of this programme is the theme melody.  Each episode opens with a few bars of whistling, the tune of which is then taken up by a full concert orchestra.  The whistling of this theme serves throughout the story to identify Dumetrius, and it is finally the cause of his dramatic capture.
