The Slovene diplomat, dr. Vladimir Rybář, aide to the Yugoslav foreign minister dr.Šubašič, and councillor to the Yugoslav Embassy in London, in 1945 held a meeting with five prominent personalities from the British public and political life, in order to obtain their views on the pressing Trieste question. The paper by means of a thorough analysis of their reported standpoints and other indices attempts to "deconspire" the identities of dr.Rybář's "informants" whom he had encoded with the letters of the alphabet.
