The Contessa Di Contini was one of The Protectors in the Gerry Anderson TV series.Nyree Dawn Porter played her,alongside Robert Vaughan as Harry Rule and Tony Anholt as Paul Buchet.The theme song was Avenues And Alleyways by Tony Christie.
There must be a few websites which have information about the series,I would recommend Action TV if you can find it,I'm having trouble accessing it at the moment.
