The murder of a cabinet minister is always highly suspicious—but when a damning piece of evidence links the victim to Toniolo, a suspected Soviet spy planted in the British government, Superintendent Luke Garvan and Major Spencer Hall know that solving this case is a matter of global importance.
As they struggle to unravel the murder from the espionage, Garvan and Hall get caught in an intricate web of anger and deceit. If they can’t separate the petty grievances from the staunch politics, however, they may forever lose the chance to finally unmask Toniolo and secure the government against further Soviet infiltration.
