When several major political figures die mysteriously, officials declare the deaths are from natural causes.

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.
