Into the Water (2017) by Paula Hawkins is a thriller.

Nell Abbott's dead body has been retrieved from the river that runs through Beckford and Nell's sister, Jules, arrives from London to care for her 15-year-old niece, Lena Abbott.

The story is about 'troublesome' women and the men who get rid of them.

One man decides that it would be better for him to avoid prison for his crime otherwise his son "would have put in care. I've seen what happens to kids who grow up i care, there's not one of them that doesn't come out damaged and perverted."

An odd comment from a man "damaged and perverted" enough to kill a woman and who didn't grow up in care.
