"A proper twisty thriller."—Sarah Pinborough

A stranger has infiltrated your family…and now he’s taking over.

Paul’s just here to help, or so he claims—sent by a charity for vulnerable people to do odd jobs for elderly widow Gwen. But for Gwen’s daughter Connie, there’s just something about Paul that rings alarm bells from day one. He’s a little too kind, a little too involved…Worse still, Gwen seems to have fallen under his spell.

The last thing Connie wants is a stranger meddling in the safe routine she’s built around Gwen. She loves being the one Gwen turns to for cooking, cleaning and company. But the more Paul visits, the more Gwen is relying on him. By the time he conveniently finds himself between homes and has no choice but to move in, Connie is certain he’s trying to push her out completely.

It’s her word against his, though, and as her attempts to unmask him become ever more desperate she’s not the only one left wondering if she’s lost her grip on reality. But when events start spiralling rapidly out of her control, should Connie wage all-out war on Paul and risk losing Gwen forever—or has that been his plan all along?
