Power and Treachery

Friday, 6am. Three powerful people die simultaneously at a luxury estate on the banks of Loch Lomond. When the G7 summit comes to Loch Lomond, DI Jade Tanner and her team are on high alert. But they aren't expecting three delegates from three of the most powerful countries to all die in suspicious circumstances - in separate locations, but at the same time. Are the deaths linked? If so, how did the killer or killers get away? And can forensic psychologist Dr Petra McBride help Jade solve the case before there's an international incident?
