In a sequel to The Housemaid, Millie lands a new position working for successful tech businessman Douglas Garrick. Cleaning their penthouse and cooking fancy meals for the Garricks is what she was expecting. What she wasn't expecting was never meeting Mrs. Garrick or the blood stains around the neck of the wife's nightgowns. Millie must decide how best to protect Mrs. Garrick without revealing her own secrets.

I was caught off-guard when The Housemaid's Secret was voted the best thriller in the 2023 Goodreads Awards, so I picked both books in the series up at the library. While The Housemaid felt like a mash-up of several popular thrillers, The Housemaid's Secret was much more original than the first book. McFadden successfully plays on your expectations and adds in some clever twists. Although The Housemaid's Secret is plagued by the same poor writing quality, the narrative is fun enough to let it slide since it's a quick read.
