Audrey Roos (1912–1982) was an American writer who, with her husband William Roos, co-authored many mystery novels, short stories, and plays. The wife-husband team, under the pseudonym Kelley Roos, often wrote romantic suspense novels featuring a married pair of sleuths, Jeff and Haila Troy, who lived in New York City. Some of their work appeared under their own names, Audrey and William Roos, rather than under the pseudonym.^[2] In 1956 they wrote Speaking of Murder, a play produced at the Royale Theatre in New York.^[1] Their television adaptation of The Burning Court by John Dickson Carr won an Edgar Award from the Mystery Writers of America in 1961.^[2]
