From MHz Choice:

Mary Higgins Clark is the Queen of Suspense, with over 3.7 million books sold worldwide. She is the all-time bestselling fiction author in France, where she received the Grand Prix de Littérature Policiè re in 1980 and was named Chevalier of the Order of Arts and Letters in the Legion of Honor. Now, the acclaimed novelist is reinvented in a new series of TV movies based on her most popular mysteries, with thrilling plots, gorgeous scenery and nerve-shattering suspense.

From MHz CHoice you can stream 2 seasons. Season 1 contains 3 episodes and  season 2 contains 4 episodes. Each episode lasts 1.5 hours. French with subtitles.

For those of you who are unfamiliar with this author, the following comes from Wikipedia:

Mary Theresa Eleanor Higgins Clark^[1] (December 24, 1927 – January 31, 2020)^[2] was an American author of suspense novels. Each of her 51 books was a bestseller in the United States and various European countries, and all of her novels remained in print as of 2015, with her debut suspense novel, Where Are the Children?, in its seventy-fifth printing.

2021 is probably not the correct date, but MHz Choice gives no date for when the series were created.

As our first quote from MHz Choice shows, her suspense novels were greatly admired in France. No wonder then, that this series comes from France with English subtitles. Look sharp because in each episode for a short screen shot someone is reading one of her plainly visible novels.

Suspense indeed!  With such engaging plots that drive to a tense conclusion, I can heartily recommend these 7 episodes.
