December 1999. London is poised on the brink of a new Millennium as the Trinity Chapter religious cult prepares for the Resurrection of its leader, Trinity the Divine, in the first minute of the first hour of the first day of the Millennium. On derelict wasteland near Kings Cross the body of a young American researcher, Jane Moorfield, is discovered. Her death shows all the signs of a massive heroin overdose, but her sister suspects otherwise.

As Alan Rosslyn (formerly of HM Customs and Excise, now working for the business intelligence consultancy ASG) helps Caroline Moorfield investigate the events surrounding her sister's death he uncovers a web of violence and deception involving the Trinity Chapter and its wealthy recruits which reaches right to the heart of the British security services. Even the upper echelons of the US government may be involved. No longer sure who he can trust, Rosslyn follows a horrific trail of brutal murders involving the Trinity Chapter's sinister caretaker Morgan Wroth from Cambridge to Geneva, forcing him to a terrifying conclusion: that the Trinity Chapter will let nothing - and no-one - prevent their leader's prophesy from being fulfilled.
