The events begin with the discovery of the body of Frank Bellamy, the Director of Technology at the CIA, inside CERN's laboratory in Geneva, at a time when scientists are searching for the Higgs boson, also known as the God particle. Between the victim's fingers is a message that reads: "The Key: Tomás Noronha." The message makes Tomás Noronha the prime suspect in the crime. The Portuguese historian soon finds himself in the crosshairs of the CIA, which dispatches a group of assassins to hunt him down. He realizes that if he wants to survive, he must either expose the crime and prove his innocence or die trying. Thus begins a journey of discovery that will lead him to the most astonishing scientific revelations ever, through several deep and unsettling questions: Does the soul exist? What happens when we die? What is the truth? Through this thrilling adventure that takes the reader into the world of consciousness and the deep secrets of nature, José Rodrigues dos Santos once again proves that he is one of the greatest mystery writers of our time. Although it falls within the realm of fiction, Solomon's Key uses real scientific information to reveal the astonishing connections between mind and matter and the mystery of existence.
