It's the week before Christmas when a lonerobber bursts into a busy Glasgow post office carrying an AK-47. An elderly mansuddenly hands his young grandson to a stranger and wordlessly helps the gunmanfill bags with cash, then he carries them to the door. He opens the door andbows his head; the robber fires off the AK-47, tearing the grandfather in two.
Detective Superintendent Alex Morrow arrives on the scene and finds that the alarm system had beendisabled before the robbery. Yet upon investigation, none of the employees canbe linked to the gunman. And the grandfather-a life-long campaigner for socialjustice-is above reproach. As Morrow searches for the killer, she discovers ahidden, sinister political network. Soon it is chillingly clear that no cornerof the city is safe, and her involvement will go deeper than she could everhave imagined.
