"When seven-year-old Lucy Ross is snatched from the carousel in Denton city park, Detective Josie Quinn joins the frantic search. She's the one who finds Lucy's sparkly butterfly backpack abandoned by the ticket booth, a note with a devastating message stuffed inside: answer your phone, or your sweet little darling will die... The next day, Lucy's parents are filled with hope when they pick up a call which they think is from their babysitter - but instead it's a chilling male voice on the line. Josie races to the babysitter's small apartment only to find her lifeless body in a tangle of sheets on her bed. Josie is faced with the most high-stakes case of her career as each new phone call from someone connected to the family ends with the shocking discovery of another body. This twisted killer wants revenge, and he won't stop until the Ross family are in pieces... Something is telling Josie that Lucy's parents aren't giving her the whole truth, but digging deeper into their lives will force her to confront a life-changing secret of her own. Does Josie have what it takes to crack this case? She has no choice if she's going to bring Lucy home alive..."--Publisher's description.
