Input: Question: What year did Davidson's first novel win the Gold Dagger award? Passage:When the war ended, he returned to the Keystone Agency and travelled all over Europe as a freelance reporter. It was during one of these trips that he came up with the idea for his first thriller, The Night of Wenceslas (1960). The novel is set in Czechoslovakia during the Cold War, and tells the story of young Nicolas Whistler, a 24-year-old Londoner whose business trip to Prague goes horribly awry. The Night of Wenceslas was an instant success, inviting favourable comparisons with such luminaries as Eric Ambler. Davidson became one of the handful of living writers to have their first novel appear in a green Penguin jacket. The book won the Crime Writers' Association's Gold Dagger Award (the top prize for crime and spy fiction in Britain) as well as the Authors' Club First Novel Award. It was filmed as Hot Enough for June (1964), with Dirk Bogarde in the role of Whistler.
