In this instant New York Times bestseller, Rebus comes out of retirement...to save his nemesis.

Retirement doesn't suit John Rebus. Being a cop is in his blood. So when DI Siobhan Clarke asks for his help on a case, Rebus doesn't need long to consider his options. Clarke's been investigating the death of a senior lawyer whose body was found along with a threatening note. On the other side of Edinburgh, Big Ger Cafferty --- Rebus's longtime nemesis --- has received an identical note and a bullet through his window. Meanwhile, DI Malcolm Fox joins forces with a covert team from Glasgow who are tailing a notorious crime family. As the cases collide, it's up to Clarke, Fox and Rebus to connect the dots and save their unlikely ally Cafferty, whose past harbors an explosive secret that could blow the case wide open --- if it doesn't kill him first.
