Book excerpt: In this crime thriller by the author of Behind Closed Doors, financial woes force a woman to accept an offer that’s too good to be true. Gemma’s business is on the brink of collapse, and there’s a real chance that she and her husband, Oliver, could lose everything they’ve worked so hard for. So, when a stranger offers financial help, Gemma ignores the red flags and accepts out of desperation. The condition? Just companionship—that’s all the stranger wants. Surely a small price to pay to get her life back? But soon Gemma finds herself being dragged so deeply into a twisted, dangerous world that she might never surface again
