"Appointment with Venus" author Jerrard Tickell, who also wrote "Odette", wrote that the germ of the idea for his novel, and delightful movie, came ten years or more in the past when he had a conversation with a Colonel "Duke" Wright in the British War Office. In 1940, Wright was O.C. at Guernsey and, with the fall of France, had the dangerous task of evacuating the garrison from the Channel Islands. After a nightmare journey, the exhausted, unshaven but triumphant Wright reported to the War Office at three in the morning that not a man had been lost. The junior officer who greeted him remarked what a pity it was that the Colonel had failed to bring any pedigreed cows with him. And added, "I suppose you couldn't go back and collect some." Tickell wrote that Colonel Wright's reply was as pungent as it was unprintable.
