Maria Kossecka - newly appointed Deputy Head of Mission in a former Soviet State - arrives in the country on the eve of a contentious presidential election that seems likely to install a pro-Western candidate. However, after spending an evening where she and her new boss, Ambassador James Reid, entertain this new man of the hour, Maria wakes to find he has been killed - his plane brought down in what looks like a targeted attack. As the British are unexpectedly tasked with overseeing the investigation into the crash by the incumbent president, Maria is forced to manage a complicated tangle of evidence, conspiracy, and competing interests inside and outside the country. Will she manage to find out the truth before civil unrest in the country threatens to escalate out of control? And what will this mean for British interests in the region?
