 When her father died toward the end of World War I, Bennett assumed care for her invalid mother.Virtually all of Bennett's work dates from 1917 to 1920, when she began to write short stories and novels to support the household.She stopped writing when her mother died in 1920; one later work published in 1923 appears to have been written during the late 'teens, and submitted to "Weird Tales" when that magazine was just starting up.
