Trust No One: A Sigma Force Novel
From #1 New York Times bestselling author James Rollins comes Trust No One, a lightning-paced standalone thriller that plunges readers into a world where history's darkest mysteries meet a deadly modern conspiracy.
At the University of Exeter's groundbreaking postgraduate program on witchcraft, folklore, and spiritualism, a British professor is brutally murdered—his own students the prime suspects. All fingers point to American Sharyn Karr, who was last seen with him. In his dying moments, he presses a centuries-old, encrypted diary into her hands: the purported journal of the enigmatic Comte de Saint-Germain, a figure whispered to possess the secret of immortality.
Hunted by ruthless forces who will stop at nothing to claim the book, Sharyn must join forces with Duncan Maxwell, a brilliant but reluctant royal heir skilled in cryptography. As they race across Europe—from the Tower of London to hidden Parisian châteaus to a fortress in the Italian Alps—ancient riddles and explosive revelations blur the line between science and sorcery, truth and deception.
With non-stop action, cutting-edge intrigue, and shocking historical twists, Trust No One is James Rollins at his most masterful.
