She is considered to have invented the "Had-I-But-Known" school of mystery writing. 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.
