The Housemaid was the hit that Lionsgate desperately needed at the end of 2025, so no one should have been surprised when they announced that they would be adapting the second book in the series. Considering the amount of competition at the Christmas box office, the fact that the first film in this series walked away with a cool $400 million worldwide is awesome. The cast for The Housemaid's Secret is filling out and we can expect that production will probably start sooner rather than later.

The Housemaid's Secret Book Summary

The Housemaid's Secret book summary from the publisher's website: "Don't go in the guest bedroom." A shadow falls on Douglas Garrick's face as he touches the door with his fingertips. "My wife… she's very ill." As he continues showing me their incredible penthouse apartment, I have a terrible feeling about the woman behind closed doors. But I can't risk losing this job—not if I want to keep my darkest secret safe…

It's hard to find an employer who doesn't ask too many questions about my past. So I thank my lucky stars that the Garricks miraculously give me a job, cleaning their stunning penthouse with views across the city and preparing fancy meals in their shiny kitchen. I can work here for a while, stay quiet until I get what I want.

It's almost perfect. But I still haven't met Mrs Garrick, or seen inside the guest bedroom. I'm sure I hear her crying. I notice spots of blood around the neck of her white nightgowns when I'm doing laundry. And one day I can't help but knock on the door. When it gently swings open, what I see inside changes everything…

That's when I make a promise. After all, I've done this before. I can protect Mrs Garrick while keeping my own secrets locked up safe.

Douglas Garrick has done wrong. He is going to pay. It's simply a question of how far I'm willing to go…"
