On the surface Keelie and Grant Swisher seem unlikely targets for an assassin; an average couple living in a nice neighbourhood and working hard to raise their two kids. But when Eve Dallas is called to a multiple homicide at the Swisher family home, she discovers a blood-bath. There are five dead – including two children – in what seems to be a professional hit. The killers breached an elaborate security system, slashed the throat of each victim while they slept; and were in and out of the house in less than ten minutes. In fact they made only one mistake. They left a survivor. Nine-year-old Nixie Swisher’s sudden urge for a midnight snack may just have saved her life. While her parents, brother and best-friend lay in their beds, oblivious to the threat, Nixie was downstairs in the kitchen getting a soda and saw far too much. But as Nixie is the only survivor of a seemingly motiveless attack, Eve knows that her priority is to keep her safe. Offering her a temporary refuge is easy, but dealing with the emotional needs of a nine-year-old girl who has lost everything isn’t. Eve can at least promise Nixie justice, but she’s chasing professionals who don’t like leaving loose ends.
