Passage:Thebacon (INN; pronounced ), or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate.

Input: Consider Input: Question: What years are the setting for Davidson's first novel? 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.
