Scott Murdoch — code-named Pilgrim — is a retired American intelligence operative who once wrote the definitive text on forensic investigation under a pseudonym. When he's called in to consult on a chillingly perfect murder in a run-down New York hotel, he doesn't yet know the case will drag him back into the world he tried to leave behind. Half a world away, a Saudi man radicalised by his father's public execution has spent years training as a doctor, quietly engineering a genetically altered virus capable of bringing a nation to its knees. As Pilgrim's investigation widens from a single crime scene into a global manhunt, he is pulled from the streets of New York to Afghanistan, Syria and Turkey, racing to identify and stop his enemy before an act of catastrophic terrorism can succeed. Two brilliant, driven men on a collision course — only one will walk away.
