Hart was born Carolyn Gimpel and was raised in Oklahoma City, Oklahoma, where she still lives. She attended Cleveland Elementary School, Taft Junior High School, and Classen High School. At the age of 11, Hart decided that she wanted to be a newspaper reporter. She worked on school papers beginning in grade school, continuing all the way through her college years.
Hart is a Phi Beta Kappa graduate of the University of Oklahoma (class of 1958), where she majored in journalism. Hart met her husband, Philip, while traveling in Europe in her junior year in college. After graduation, while her husband attended law school, Hart worked as a reporter for The Norman Transcript. She gave up journalism after the birth of her son, Philip Jr.
In 1964, the year her daughter, Sarah, was born, Hart won a writing contest calling for a mystery novel that would appeal to adolescent girls, sponsored by Dodd, Mead and Calling All Girls. She went on to write several more teenage and young adult mysteries between 1965 and 1972. From 1972 to 1987, she wrote nine stand-alone suspense novels and mysteries which had only modest success. Until the publication of books by Marcia Muller, Sara Paretsky, and Sue Grafton, publishers had little interested in mysteries written by female American authors. The success of these authors opened the door for Hart's Death on Demand series in 1987.
Hart's stand-alone World War II novel Letter from Home was nominated for the Pulitzer Prize for Fiction by the Oklahoma Center for Poets and Writers at Oklahoma State University–Tulsa. She has twice appeared as one of the featured mystery authors at the Library of Congress National Book Festival in Washington, D.C.
Hart has won awards throughout her four-decade writing career.

Death on Demand
Hart's first commercially successful adult mystery series features Annie Laurance, proprietor of the Death on Demand bookstore, located in the fictional South Carolina island community of Broward's Rock. By using a mystery bookstore for her background, Hart has given her characters the opportunity to talk freely about other mystery authors and books. One of the ongoing themes of the series is a contest whereby the first customer who correctly identifies a series of five mysteries from the clues in a painting hanging in the shop wins his or her choice of a novel.
