Biography B.A. Paris was born in the United Kingdom to a French mother and Irish father, the third of six children. After completing her education, she moved to France, where she spent much of her adult life initially working as a trader at an international bank in Paris before retraining as an English teacher. Together with her husband, she ran a language school while raising their five daughters.

Writing came later in life when one of her daughters suggested she enter a writing competition. Although she did not win, the experience led her to continue writing. Her debut novel, Behind Closed Doors, was published in 2016 and became an instant international bestseller, selling over three million copies in the UK alone and launching her career as one of the most widely read authors in the psychological thriller genre. She is now published by HarperCollins in the UK and St. Martin's Press in the US, and lives in Hampshire, England.

Novels Behind Closed Doors Paris's debut novel, Behind Closed Doors, was acquired in 2014 by her agent Camilla Bolton at the Darley Anderson Literary Agency in London and published in 2016 by HarperCollins in the UK and St. Martin's Press in the US. It became an instant New York Times and Sunday Times number one bestseller. Paris was nominated in the Best Debut Author and Best Mystery & Thriller categories at the Goodreads Choice Awards in 2016, and in 2017, Behind Closed Doors won the Gold Nielsen Bestseller Award for UK sales of 500,000 copies, making Paris the only debut fiction author to win a Gold award that year. The novel went on to win the Platinum Nielsen Bestseller Award in 2019 for sales of over one million copies in the UK alone. More than 6 million copies have now been sold globally since its release.

The novel explores themes of psychological manipulation and coercive control in intimate relationships. Paris has spoken in interviews about being inspired by real accounts of women in controlling relationships. In a Goodreads Q&A in 2017, she noted that she was glad the book had "brought the subject of psychological abuse — which is so much harder to prove than physical abuse — into the open."

The Breakdown The Breakdown was published in 2017 and won the Silver Nielsen Bestseller Award in 2025 for UK sales of 250,000 copies. The film and television rights were acquired by Stone Village Productions in 2016 and the film adaptation, titled Blackwater Lane and directed by Jeff Celentano, was released in June 2024 starring Minka Kelly, Maggie Grace and Dermot Mulroney.
