The Murder at the Vicarage
In the 1950s, Denk began appearing in television roles, highlighted by a performance as Margot in "Besuch Aus Der Zone" (1958), and Leonida in "Ein Tag in Paris" (1966), in which Denk co-starred with Horst Tappert, who in 1975 would invite her to appear in an episode of his popular and long-running hit series, "Derrick (TV series)". Denk also appeared as Frau Price-Ridley in a popular adaptation of Agatha Christie’s "The Murder at the Vicarage", produced in German as "Mord im Pfarrhaus" (1970).
