Gill Kayo was originally drawn by Eric Gill in 1932 and issued by Monotype in 1936. In 1980, a condensed variant of the heavyweight was added by the Letraset studio in 1980. In 1981, Herbert Carl Traue used Gill Kayo Condensed for the jacket of Verrat in Rot (“Treason in red”), and contrasted it with the family’s Light weight.
Rudolf Ströbinger’s novel is based on historical events that took place in Brno in 1945: in the final phase of the Second World War, cousins Alois Bauer and Vladimír Blažka carried out an assassination attempt on SS-Hauptsturmführer August Gölzer, a representative of the German protectorate in occupied Czechoslovakia. The title of the book refers to the fact that the two communist resistance fighters were denounced by one of their comrades, who revealed their names to the Gestapo under duress.
