A techno-thriller with historical intrigue, drone warfare, and a villain inspired by Dracula’s legacy—this fifth installment in the Brit in the FBI series is as cerebral as it is action-packed.
In The Sixth Day, Special Agents Nicholas Drummond and Michaela “Mike” Caine of the FBI’s elite Covert Eyes team face one of their most complex and chilling cases yet.

🧠 Plot Overview
When high-profile political figures begin dying under mysterious circumstances—initially ruled as natural causes—a drone spotted near the scene of one death raises red flags. The Covert Eyes team is called in to investigate what quickly becomes a series of targeted assassinations.
Their search leads them to Roman Ardelean, a cybersecurity genius and descendant of Vlad the Impaler. Ardelean believes the Voynich Manuscript, a real-world historical enigma, holds the key to curing his twin brother’s rare blood disorder. As he spirals into obsession, he unleashes a deadly plan to punish those he believes betrayed him—including a devastating attack on London.
With the help of Dr. Isabella Marin, a linguist and expert in cryptophasia (twin language), Nicholas and Mike must decode the manuscript, stop the assassinations, and prevent a catastrophe—all while navigating a web of myth, science, and madness.
