Mary Higgins Clark's fame as a writer was achieved against heavy odds. Born and raised in the Bronx, her father died when she was eleven and her mother struggled to raise her and her two brothers. On graduating from high school, she went to secretarial school, so she could get a job and help with the family finances. After three years of working in an advertising agency, travel fever seized her. For the year 1949, she was a stewardess on Pan American Airlines' international flights. "My run was Europe, Africa and Asia," she recalls. "I was in a revolution in Syria and on the last flight into Czechoslovakia before the Iron Curtain went down. After flying for a year, she married a neighbor, Warren Clark, nine years her senior, whom she had known since she was 16. Soon after her marriage, she started writing short stories, finally selling her first to Extension Magazine in 1956 for $100.
Left a young widow by the death of her husband from a heart attack in 1964, Mary Higgins Clark went to work writing radio scripts and, in addition, decided to try her hand at writing books. Every morning, she got up at 5 AM and wrote until 7 AM, when she had to get her five children ready for school. Her very first book was a biographical novel about George Washington, inspired by a radio series she was writing, "Portrait of a Patriot." Originally published in 1969 by Meredith Press with the title Aspire to the Heavens, it was discovered years later by a Washington family member and re-issued in 2002 with the title, Mount Vernon Love Story.
Mary Higgins Clark's first suspense novel, Where Are the Children? was published by Simon & Schuster in 1975. It became a bestseller and marked a turning point in her life and career. It is currently in its 75th edition in paperback and was re-issued in hardcover as a Simon & Schuster classic.
