A serial killer holds New York in his grip. The explosion of a twenty-two-storey building, followed by the casual discovery of a letter, lead the police to face up to a dreadful reality: some of New York's buildings were mined at the time of their construction. But which ones? And how many? A young female detective hiding her personal demons behind a tough facde, and a former press photographer with a past he'd rather forget, and for which he still seeks forgiveness, are the only hope of stopping this psychopath. A man who does not even claim responsibility for his actions. A man who believes himself to be God.
