The further adventures of those indomitable spinsters, Tish, Aggie and Lizze. Mary Roberts Rinehart (August 12, 1876-September 22, 1958) was a prolific author often called the American Agatha Christie. She is considered the source of the phrase "The butler did it", although she did not actually use the phrase herself, and also considered to have invented the "Had-I-But-Known" school of mystery writing. She was born in Allegheny City, Pennsylvania, which has been a part of the city of Pittsburgh since 1907. Her father was a frustrated inventor, and throughout her childhood, the family often had financial problems. She was left-handed at a time when that was considered inappropriate, and she was trained to use her right hand instead. She attended public schools and graduated at the age of sixteen, then enrolled at the Pittsburgh Training School for Nurses at Homeopathic Hospital, where graduated in 1896. She described the experience as "all the tragedy of the world under one roof." After graduation she married Stanley Marshall Rinehart, a physician whom she met there. They had three sons and one daughter: Stanley Jr., Frederick, Alan, and Elizabeth Glory. During the stock market crash of 1903 the couple lost their savings, and this spurred Rinehart's efforts at writing as way to earn income. She was 27 that year, and she produced 45 short stories. In 1907 she wrote The Circular Staircase, the novel that launched her to national fame. According to her obituary in The Pittsburgh Post-Gazette, that book alone sold a million and a quarter copies. Her regular contributions to the Saturday Evening Post were immensely popular and helped the magazine mold American middle-class taste and manners. Rinehart's commercial success sometimes conflicted with her domestic roles of wife and mother. Yet she often pursued adventure, including a job as the first woman war correspondent at the Belgian front during World War I. In the early 1920s the family moved to Washington, DC when Dr. Rinehart was appointed to a post in the Veterans Administration. He died in 1932, but she continued to live there until 1935, when she moved to New York City. There she helped her sons found the publishing house Farrar & Rinehart, serving as its director. She also maintained a vacation home in Bar Harbor, Maine, where she was involved in a real-life drama in 1947. Her Filipino chef, who had worked for her for 25 years, fired a gun at her and then attempted to slash her with knives, until other servants rescued her. The chef committed suicide in his cell the next day. Rinehart suffered from breast cancer, which led to a radical mastectomy; she eventually went public with her story, at a time when such matters were not openly discussed. The interview "I Had Cancer" was published in a 1947 issue of the Ladies' Home Journal and in it Rinehart encouraged women to have breast examinations. "The Rinehart career was crowned with a Mystery Writers of America Special Award a year after she published her last novel ... and by the award, as early as 1923, of an honorary Doctorate in Literature from George Washington University." She died at age 82 in her Park Avenue home in New York City.
