Mignon Good (1899-1996) was born in Lincoln, Nebraska. She studied at Nebraska Wesleyan University from 1917 to 1920. In 1923 she married Alanson C. Eberhart, a civil engineer. After working as a freelance journalist, she decided to become a full-time writer. In 1929 her first crime novel was published featuring 'Sarah Keate', a nurse and 'Lance O'Leary', a police detective. This couple appeared in another four novels. In the Forties, she and her husband divorced. She married John Hazen Perry in 1946 but two years later she divorced him and remarried her first husband. Over the next forty years she wrote a novel nearly every year. In 1971 she won the Grand Master award from the Mystery Writers of America. She also wrote many short stories featuring banker/amateur sleuth James Wickwire (who could be considered a precursor to Emma Lathen's John Putnam Thatcher) and mystery writer/amateur sleuth Susan Dare.
