Millie and Enzo move with their children to a house that is too expensive for their budget. The new neighbors are of course suspicious and unpleasant. Then something shocking happens.
There is a fair amount of consensus among readers about this book, that it is a completely pointless effort. Many have been disappointed, and hope that the series will end. Like many others, I did not recognize these characters. Nothing really exciting happened or was happening.
Personally, I never like it when "thrillers" focus only on boring everyday life and home life.
The Housemaid Is Watching takes place 11 years after the previous book. Quite a leap in time. And of course, everyone always wants that idyllic family life in the suburbs. Even those who have previously lived a slightly more unconventional life.
