Mignonette Good Eberhart, born July 6, 1899 in Lincoln, Nebraska, attended Nebraska Wesleyan University before publishing her first novel Patient in Room 18 in 1929. Eberhart penned over 50 novels and numerous short stories, many of which have been adapted for film and television. In 1971, she received the Grand Master Award from the Mystery Writers of America. She is also a past president of the Mystery Writers of America.
She began to write in her early teens, "mainly," she says, "because I preferred writing to studying Caesar's Commentaries and algebra. "Known as "America's Agatha Christie," she wrote a total of 59 novels, the last published in 1988, shortly before her 89th birthday. Eight of her novels were adapted as movies, beginning in 1935 with While the Patient Slept. The last adaptation, based on the book Hasty Wedding, was the movie Three's a Crowd released in 1945. Eberhart was one of the founders of the modern romantic suspense novel. In an unusual twist for the time, her mysteries featured female heroines. The year after her first novel was published, Agatha Christie followed her lead and introduced another female detective, Jane Marple.
