The Sixth Day

The Sixth Day

(Book #5 of A Brit in the FBI)
Special agents Nicholas Drummond and Michaela Caine take on a ruthless mastermind in this heart-stopping thriller in the New York Times bestselling A Brit in the FBI series.

When several major political figures die mysteriously, officials declare the deaths are from natural causes. When the German Vice-Chancellor dies on the steps of 10 Downing Street and a drone is spotted hovering over the scene, the truth becomes clear—these high-profile deaths are well-constructed assassinations. The Covert Eyes team is tasked to investigate. That same day, an American is killed in London, the small bite marks in her neck matching a series of murders taking place across Europe.

With the help of Dr. Isabella Marin, a young expert in the Voynich Manuscript and twin speak, Nicholas and Michaela discover they are hunting the same individual: Roman Ardelean, a cybersecurity genius and descendant of Romanian Vlad the Impaler—often romanticized as Dracula. Roman believes the Voynich will unlock the secret to curing his severely ill twin brother’s blood disorder and is willing to murder anyone who gets in his way, including Nicholas and Michaela. Along with MI5, the Covert Eyes must race against the clock to find Ardelean before he unleashes a devastating attack on London intended to destroy those he believes betrayed him.

With gripping tension and suspense, New York Times bestselling authors Catherine Coulter and J.T. Ellison “are really on an amazing roll with their outstanding A Brit in the FBI series” (RT Book Reviews).
