"A man walks into a diner, bleeding and armed. He claims he’s being hunted. That something’s coming. That no one’s safe. Hours later, he’s found dead in a holding cell. John Beckett, former MI6, doesn’t buy the suicide story. Neither does Detective Maggie Lee. When the evidence vanishes and questions are brushed aside, Beckett and Lee start digging. Their search leads them to a powerful tech company, a private security firm, and a missing device everyone wants but no one will admit exists."
