Anna Katharine Green (November 11, 1846 – April 11, 1935) was an American poet and novelist. She was one of the first writers of detective fiction in America and distinguished herself by writing well plotted, legally accurate stories. Green has been called "the mother of the detective novel." She was born in Brooklyn, New York on November 11, 1846. Green had an early ambition to write romantic verse, and she corresponded with Ralph Waldo Emerson. When her poetry failed to gain recognition, she produced her first and best known novel, The Leavenworth Case (1878), praised by Wilkie Collins, and the hit of the year. She became a bestselling author, eventually publishing about 40 books. Ellen Higgins, professor of a course on women and detective fiction at the University at Albany, delivered a talk on "The Female Rivals of Sherlock Holmes" at an international conference on Sherlock Holmes at Bennington College in 1994 with a paper that offered a revisionist feminist view of Sherlock. Higgins chronicled the work of Green, who published The Leavenworth Case, which became a best-seller a decade before Arthur Conan Doyle brought out his first Holmes story. "I only found out afterward that some people were a little upset with it because they don't want to hear about women competing with the master," Higgins said. Green is credited with shaping detective fiction into its classic form, and developing the series detective. Her main character was detective Ebenezer Gryce of the New York Metropolitan Police Force, but in three novels he is assisted by the nosy society spinster Amelia Butterworth, the prototype for Miss Marple, Miss Silver and other creations. She also invented the 'girl detective': in the character of Violet Strange, a debutante with a secret life as a sleuth. Indeed, as journalist Kathy Hickman writes, Green "stamped the mystery genre with the distinctive features that would influence writers from Agatha Christie and Conan Doyle to contemporary authors of suspenseful "whodunits." In addition to creating elderly spinster and young female sleuths, Green's innovative plot devices included dead bodies in libraries, newspaper clippings as "clews," the coroner's inquest, and expert witnesses. Yale Law School once used her books to demonstrate how damaging it can be to rely on circumstantial evidence. Written in 1878, her first book, The Leavenworth Case: A Lawyer's Story, sparked a debate in the Pennsylvania Senate over whether the book could "really have been written by a woman."
