Writing as John Ironside, Euphemia Margaret Tait was a British author born in Liverpool in 1866 and died in 1945. She is chiefly remembered for crime and mystery novels published under a male pseudonym.
Her work appeared in the first half of the 20th century, and The Red Symbol is one of the titles most often associated with her today. Modern library and public-domain listings continue to preserve her books, which has helped keep her name alive for readers interested in vintage detective fiction.
Very little widely confirmed biographical detail seems easy to verify from major public sources beyond her identity, dates, and the fact that John Ironside was her pseudonym. That scarcity gives her a slightly elusive place in literary history, but it also adds to the appeal for readers who enjoy rediscovering overlooked crime writers.
