'Their blood shall be upon them.'
A teenager is found naked and wandering in a lane near Stockport. He can't answer any questions about the serious injuries he's sustained, only repeatedly recite a biblical passage.
DCI Ted Darling's team take the case and discover he's been missing for six months - and he's not the only young person to have suffered the same fate.
Ted's tied up in an important court case where the father of the young defendant seems prepared to stop at nothing to bring the case crashing down around him.
It doesn't help when he's told his team must lose a member and Ted has to choose who it will be.
Whoever the kidnapper is, he seems to have a set timetable for his abductions. Can Ted catch him before he strikes again?
