Working alone and late at night, he strives to recreate his forefather's discovery. In the weeks that follow, a wave of murders breaks across London. Metropolitan Police officers race to trace the killer. But as the net closes on a young man with mental health problems, one driven detective begins to have her doubts. Can she catch the real killer, before he commits his most heinous act of all?
