"A masterful mystery-thriller rooted in historical truth." In an ancient abbey south of Rome, a mysterious mosaic stone is stolen—one the monks believe holds the power of resurrection itself. Colonel Camarata calls in Professor Cariello, who happens to be leading an archaeological dig nearby. As they investigate, shocking connections emerge: the missing stone is believed to have belonged to none other than Saint Thomas Aquinas—the father of modern theology, the man who "proved" the existence of God, and who, legend says, once possessed the mythical Philosopher's Stone. But they are not the only ones searching. Powerful forces, both seen and unseen, are closing in. When a monk turns up dead, the case becomes personal—and far more dangerous than Cariello could have imagined. A gripping thriller of theology, mystery, and murder—set in the hauntingly beautiful hills of Italy and based on real historical events. "As suspenseful as The Da Vinci Code and as rich as The Name of the Rose." "A brilliant Italian crime story—atmospheric, intelligent, and unputdownable." "Once again, Ringuer blends fact and fiction into something unforgettable."
