When a Man Marries is a romantic comedy with mystery overtones the plot unfolds as several bright young characters suddenly find themselves sequestered in a large house under quarantine because the butler has just been stricken with smallpox. About the author: Mary Roberts Rinehart (August 12, 1876 - September 22, 1958) was an American writer, often called the American Agatha Christie. Rinehart published her first mystery novel The Circular Staircase in 1908, which introduced the "had I but known" narrative style. Rinehart is also considered the source of "the butler did it" plot device in her novel The Door (1930), although the exact phrase does not appear in her work. She also worked to tell the stories and experiences of front line soldiers during World War I, one of the first women to travel to the Belgian front lines. Rinehart wrote hundreds of short stories, poems, travelogues and articles. Many of her short stories, books, and plays were adapted for movies, such as Bab: A Sub-Deb (1917), The Bat (1926), The Bat Whispers (1930), Miss Pinkerton (1932), and The Bat (1959 remake). The novel The Circular Staircase was first adapted to the screen as a silent film in 1915, and later as an episode in the TV show Climax! in 1956. In 1933 RCA Victor released The Bat as one of the early talking book recordings. She co-wrote the 1920 play The Bat which was later adapted into the 1930 film The Bat Whispers. The latter influenced Bob Kane in the creation of Batman's iconography. ... (Wikipedia.org)
