Hanging Hill by Mo Hayder

After a teenage girl is found murdered near a canal, two estranged sisters are forced back into each other’s lives—one a driven detective on the case, the other a financially desperate single mother drawn into dangerous compromises to protect her daughter. As the investigation threads through elite social circles, online exploitation, and a risky escort scheme, long-buried secrets surface and loyalties are tested. The result is a tense, twist-filled descent into obsession and survival that asks how far someone will go to keep family safe.
