A grandfather brutally murdered in a post office raid. A corrupt politician fighting for his future. A police force up for sale. Three crimes leading to one question - who really runs Glasgow? Recently returned to work after the birth of her twins, DS Alex Morrow is called in to head the murder enquiry. The grandfather had helped the gunmen before being shot - was as it a moment of madness, a noble act of self-sacrifice, or did the old man and his killer share a dark past? One city, three crimes and a powerful connection that runs from Glasgow's dark criminal underworld to the international spheres of the super rich.
