James Wentworth Day (21 April 1899 – 5 January 1983) was a British writer and broadcaster, of the Agrarian Right school and essentially a High Tory. He lived for most of his life in East Anglia, an area which would always be his first love; he had a particular interest in wildfowling, and at one time owned Adventurers' Fen, a piece of marshland in Cambridgeshire. He was also a ghost hunter, and wrote several books about this interest. He may be best remembered for his journey around the farms of East Anglia on horseback during World War II, as detailed in his book Farming Adventure (later reprinted under the title Wartime Ride), while for many years he was closely associated with the East Anglian magazine.
Born in Exning, Suffolk he was educated at Newton College, Newton Abbot and Cambridge before seeing active service in World War I. He became a journalist after his war service, working for Express newspapers and Country Life (as well as other sporting papers). He edited the Illustrated Sporting and Dramatic News. He also became personal assistant to Lucy, Lady Houston and for a time shared some of her extreme ideas in supporting Benito Mussolini, although he was highly suspicious of Adolf Hitler. He became a propaganda adviser to the Egyptian government in 1938 and spent the Second World War as a correspondent in France and as Near East correspondent of the BBC until he was invalided in 1943.
