William Roos

William E. Roos (May 25, 1911, Pittsburgh, Pennsylvania – March 1, 1987, United States) was an American novelist, playwright, and screenwriter. He authored works using both his own name and the pseudonym William Rand. He also co-authored several works with his wife, the writer Audrey Roos, under the pen name Kelley Roos. These included more than twenty mystery novels; nine of which featured the married sleuths Jeff and Haila Troy. In 1961 the couple won the Edgar Allan Poe Award from the Mystery Writers of America. As a solo writer he authored several plays which were staged on Broadway and multiple teleplays for American television.

Life and career William Roos was born on May 25, 1911, in Pittsburgh, Pennsylvania. He was educated at the Carnegie Institute of Technology (now Carnegie Mellon University) in his native city. There he met his wife, Audrey Kelley, and after marrying her the couple moved to New York City.

As a solo writer Roos wrote several plays under his own name, many of which were staged on Broadway; including Triple Play (1937), The Life of Reilly (1942) January Thaw (1946), Boy Wanted (1947), Peep Show (1950), and Belles On Their Toes (1952). Under the pseudonym William Rand he adapted the 1938 novel The Four of Hearts by Ellery Queen into a 1949 stage play entitled The Four of Hearts Mystery. He penned the story for the 1948 Broadway musical As the Girls Go whose plot was set in a future United States when the nation elects its first female president. He also authored the musical book for the 1951 Broadway musical Courtin' Time; collaborating with Jack Lawrence and Don Walker who co-wrote the music and lyrics. That work was itself an adaptation of Eden Phillpotts's 1916 play The Farmer's Wife. Roos also co-authored one play with his wife Audrey for Broadway, Speaking of Murder (1956). The 1960 film Scent of Mystery starring Elizabeth Taylor and Peter Lorre was adapted from their 1947 mystery novel Ghost of a Chance.

For television, Roos wrote multiple teleplays for the Kraft Television Theatre and Goodyear Television Playhouse; sometimes by himself under his own name and sometimes in collaboration with his wife under their own names or as Kelley Roos. Some of these were adaptations of his stage plays for appearance on television, and others were television adaptations of works he co-authored with his wife or works originally written by other mystery writers.
