Near the start of bestseller Coulter and Ellison's exciting fifth Brit in the FBI thriller (after 2017's The Devil's Triangle), Germany's vice chancellor, Heinrich Hemmler, collapses and dies as he enters 10 Downing St. to confer with the British prime minister about letting more refugees into the U.K. The day before, Chapman Donovan, a wealthy Irish land owner with whom Hemmler had some business, dropped dead of a heart attack outside his home, according to news reports. When it becomes clear that both men were murdered by drones, FBI agents Michaela "Mike" Caine and Nicholas Drummond investigate, aided by their Covert Eyes team. The drone attacks coincide with a major computer security breach tied to a cybersecurity program designed by evil genius Roman Ardelean, who the reader soon learns is behind the attacks. Meanwhile, Ardelean, a descendant of 15th-century Romanian tyrant Vlad the Impaler, is seeking some newly discovered missing pages from the cryptic Voynich Manuscript that contain information regarding a blood disease cure. Coulter and Ellison smoothly mix contemporary political issues with eerie historical legend in this fast-paced outing sure to appeal to fans and newcomers alike.
