Mary Higgins Overview

Early Life

Mary Higgins Clark, born Mary Theresa Eleanor Higgins on December 24, 1927 in The Bronx, New York, was the daughter of Luke Joseph Higgins and Nora C. Durkin, with Luke hailing from Ireland.

She was blessed with two brothers, Joseph and John; however, Joseph tragically passed away shortly after graduating from high school, due to contracting spinal meningitis during his service in the Navy.

At the tender age of 7, Higgins Clark wrote her first poem. As a young child, she was also fond of writing short plays. Her family owned an Irish pub and had a home in The Bronx, plus a cottage on Long Island Sound.

But due to the economic strain caused by the Great Depression, many of their patrons were unable to pay their bar tabs, and the Clark family started to struggle financially in the late 1930s.

In 1939, Mary was forced to leave the security of her home when her father passed away in his sleep; her mother needed to rent out her room in order to provide for the family.

With her father’s passing, Mary was forced to attend Saint Francis Xavier Grammar School; however, due to her hard work and dedication, Mary was eventually awarded a scholarship to study at Villa Maria Academy, where the teachers encouraged and fostered her budding passion for writing.

When Joseph passed away, the Navy promised Nora a life pension, and Mary was relieved from the financial burden of helping to pay the bills.

At one point, the family had to resort to taking a drastic measure – She took a job as a switchboard operator at the Shelton Hotel – in order to make ends meet, yet sadly, it was still not enough to save their home, and so they eventually had to move into an apartment.


After enrolling at Wood Secretarial School, Higgins Clark embarked on a career as a secretary in Remington Rand’s internal advertising division. To further her skills, she took night classes in advertising and promotion and soon was writing catalog copy for Remington Rand.

Interestingly enough, she also had the chance to model in their brochures alongside future star Grace Kelly.

In December 1949, Mary decided to forsake her career as a flight attendant for Pan American Airlines when she married Warren Clark; however, her passion for writing ultimately led her to New York University, and in 1956, her short story “Stowaway” was published by “Extension Magazine.”

On the fateful day in 1964 when Higgins Clark secured the role of writing radio scripts, tragedy struck – Warren had a fatal heart attack and his mother, upon hearing the news of her son’s death, collapsed and passed away.

Mary, however, saw a beacon of light in the darkness; following her appointment to write four-minute scripts for the “Portrait of a Patriot” radio segment, she was requested to take on two additional radio series.

By the late 1960s, magazines had ceased to print short stories to the extent they had previously, thus prompting Higgins Clark’s agent to suggest she compose a novel.

The outcome of that suggestion was “Aspire to the Heavens,” a work of fiction depicting the relationship between George and Martha Washington. Published in 1968, the novel unfortunately was “remaindered as it came off the press”.

In 1971, Mary made the bold decision to enroll at Fordham University at Lincoln Center, and eight years later she achieved the extraordinary success of graduating summa cum laude in 1979.

In 1975, Mary decided to switch to suspense with her second novel, and Simon & Schuster purchased the book for a staggering $3,000.

Three months later, the paperback rights sold for an incredible $100,000. Entitled “Where are the Children?” it became an instant bestseller, and Simon & Schuster offered an unprecedented $1.5 million for Mary’s subsequent novel, 1977’s “A Stranger is Watching.”

In the ’80s, she published novels such as

  • “A Cry in the Night” (1982), “Weep No More, My Lady” (1987)
  • “While My Pretty One Sleeps” (1989)
  • “Loves Music, Loves to Dance” (1991)
  • “I’ll Be Seeing You” (1993)
  • “Let Me Call You Sweetheart” (1995)
  • “Silent Night” (1995)
  • “Bad Behavior” (1995)
  • “Moonlight Becomes You” (1996)
  • “Pretend You Don’t See Her” (1997)
  • “You Belong to Me” (1998)
  • “We’ll Meet Again” (1999) in the’90s.

In 2007, Mary Higgins Clark delighted readers with the publication of her first children’s book, “Ghost Ship,” followed shortly by “No Place Like Home” (2005), “Two Little Girls in Blue” (2006), “I Heard That Song Before” (2007), and “Just Take My Heart” (2009).

In 2010, La Sabotière, a Paris-based company, kickstarted the adaptation of Mary’s crime novels into TV movies.

In 2019, it was announced that La Sabotière had joined forces with Montréal’s Reel One Entertainment and the U.S.’s Element 8 Entertainment to create an anthology series based on her novels, with the first season based on “I’ll Be Seeing You.”

The “Under Suspicion” series by Mary Higgins Clark and Alafair Burke spans from 2014-2020, with titles such as “I’ve Got You Under My Skin” (2014), “The Cinderella Murder” (2014), “All Dressed in White” (2015), “The Sleeping Beauty Killer” (2016), “Every Breath You Take” (2017), “You Don’t Own Me” (2018), and “Piece of My Heart” (2020).

An adventure through time, this series will have you hooked with suspense and thrill! Not only did Mary pen the beloved “Alvirah and Willy” series, but she also wrote stories that sometimes interweaved with her daughter Carol’s “Reagan Reilly” series.
