Gavin held positions as a history lecturer at Aberdeen and at the University of Glasgow.[1] She stood unsuccessfully as a Unionist candidate in two parliamentary elections in the 1930s.[1]
During World War II, she worked in France and the Netherlands for Kemsley Newspapers.[1] She also wrote a biography of Edward VII, published in 1941. She was a correspondent in the Middle East and Ethiopia after the war, for the Daily Express. After marriage, she worked a few years on the staff of Time magazine in New York.[2] She wrote about her wartime experiences in Liberated France (1955).[4]
Most of Gavin's literary output was in the genre of historical romance.[5] "Her characters are attractive flesh-and-blood people, her narrative adventurous and suspenseful, and her use of history skillful and unerring," reported one American reviewer in 1957.[6] The University of Aberdeen awarded her an honorary DLitt in 1986.[1] The Catherine Gavin Room there is named in her honour.[1] The university has a 1940 portrait of her, in oil, by Elizabeth Mary Watt.[7]
In 1948, Gavin married American advertising executive John Ashcraft[2] and moved to the United States with him.[1] She was widowed in 1998, and died in 1999, aged 92.[1]
