“The Housemaid”: How a Housemaid Became the Protagonist of a Global Bestseller

In 2022, few could have predicted that a novel by a woman doctor, writing during breaks between hospital shifts, would become the main literary event of the decade. But just three years later, “The Housemaid” by Frida McFadden took the top spot among global bestsellers, surpassing recognized masters of the genre. Its print runs exceeded 36 million copies, and the adaptation with Sydney Sweeney and Amanda Seyfried grossed 300 million dollars at the box office. How did a novel about a former prisoner who became a housemaid in a wealthy home captivate the planet and make millions of readers hold their breath on every page?

A Plot That Keeps You Gripped

Milly Calhoun is a young woman who has just been released from prison on parole. She lives in her old car, unable to find work due to her conviction, and understands that another failure will send her back behind bars. Desperate, she responds to an advertisement by the wealthy Winchester family, which is looking for a housemaid with accommodation. The homeowner, Nina, offers her a great salary and a separate room — at first glance, it seems that Milly has hit the jackpot [reference:0][reference:1].

However, the idyll soon begins to crack. Milly’s room is locked from the outside [reference:2]. Nina behaves unpredictably: she asks for something to be done, then shouts that she didn’t ask for anything [reference:3]. She is jealous of her husband Andrew’s attention to the housemaid, and their daughter Cecilia behaves strangely [reference:4]. Milly finds herself trapped: endure the abuse or end up back on the streets [reference:5].

The book is divided into three parts. The first is from Milly’s perspective, as she tries to figure out what is happening. The second is from Nina’s perspective, revealing a completely different picture to the reader. In the finale, we return to Milly, and everything we knew is turned on its head [reference:6][reference:7]. This unconventional narrative technique is one of the main reasons why the book keeps you on the edge of your seat until the last page.

As it turns out, Andrew, who seemed like an charming and caring husband, is actually the main antagonist. For years, he subjected Nina to physical and psychological abuse, locking her in the very room that Milly now occupies [reference:8]. He concocted a murder-suicide attempt to portray Nina as insane and gain full control over her life [reference:9]. Nina, in turn, hired Milly, knowing that Andrew would be interested in her — this was her cunning plan to escape her husband [reference:10]. When the truth comes to light, Milly finds herself locked in a room, but with the help of Nina, she manages to fight back against the abuser [reference:11]. In the end, Andrew is dead, Milly starts a new life, and Nina takes responsibility [reference:12].

Why It Became a Bestseller

The success of “The Housemaid” is not a coincidence but the result of a perfect fit with the times. Firstly, it is incredibly fast-paced and “devourable.” Readers call the book an “addiction,” a “nightmare,” and a “thriller without brakes” [reference:13]. Each chapter is like a little jolt of adrenaline [reference:14]. This is the case where you can’t put the book down, even if it’s two in the morning [reference:15].

Secondly, McFadden’s formula is a classic “domestic” thriller, inspired by “Rebecca” and “Jane Eyre” [reference:16]. The familiar setting (a wealthy home, the perfect family) turns into a field of psychological warfare, and “shocking twists” have become the author’s signature [reference:17][reference:18]. As The Independent notes, “realism is not the strongest side of McFadden, but it is not her goal. Her goal is to pull the rug out from under the reader” [reference:19].

Thirdly, the book fits perfectly into the age of social media, especially TikTok, where its “provocative plot” and “scandalous content” have become the subject of thousands of discussions [reference:20]. It was the virality in the book that turned the novel from a good thriller into a global phenomenon.

Fourthly, the author herself adds intrigue. Frida McFadden is a pen name [reference:21]. Behind it is a practicing doctor who wrote her novels between hospital shifts [reference:22]. She does not seek fame, but her books speak for themselves: 27 novels in 13 years, 36 million sales, 10 books in the top 50 Kindle [reference:23][reference:24].

What Made It Popular Worldwide

“The Housemaid” became a global hit for several reasons. Firstly, the theme of domestic violence and psychological manipulation is universal. It resonates with readers regardless of country and culture. Secondly, the protagonist, a former prisoner trying to survive in an inhospitable world, elicits deep empathy. Thirdly, the book offers a rare combination: it is light enough for mass readers, but dark and complex enough not to be superficial.

In 2025, “The Housemaid” became the best-selling book of the year worldwide, surpassing even recognized authors [reference:25]. The adaptation with Sydney Sweeney only added fuel to the fire [reference:26]. As critics note, the book has become a “textual example of McFadden’s formula”: a poor girl, a wealthy family, cracks in the facade — and the reader races down the dark corridor, knowing that there is a door at the end, behind which lies something terrible [reference:27].

“The Housemaid” is not literature for literature’s sake. It is a thriller attraction that gives the reader what they crave: thrills, unexpected twists, and a sense that you have experienced something real, even if it is on paper. It is for this reason that it was loved by millions. And it is why it will remain in history as one of the most successful novels of the 21st century.
