Recalls Harlan Coben - though for my money Jackson is the better writer' GuardianI can help you, Cal. I can help you solve the murder of Cindy Mellish.' A grisly murder in a shabby New York bookstore seems to hold a special significance for Detective Callum Doyle: the victim's been marked with a message that could have been left specially for him. But why? Then the sinister phone calls start. Doyle is told more deaths are planned but the caller will give him clues - on condition he keeps them to himself. So begins his dilemma. If he turns the offer down he will have nothing to go on. But if he accepts and gets it wrong, he will have concealed knowledge that could have stopped a killer. As more deaths follow, increasingly vicious and apparently random, the pressure on Doyle to find a link becomes unbearable. Does he continue to gamble with people's lives? Or must he sacrifice everything to defeat a ruthless and manipulative enemy? Furiously fast-paced, totally unpredictable and unforgettable, this is a masterpiece from the acclaimed author of Pariah.
