A dreadful past

A chance sighting of a vase for sale in an antiques shop leads Detective Chief Inspector George Hennessey and his team to take a fresh look at a twenty-year-old unsolved murder case. As the investigation opens out and links are made to other unsolved murders in the Vale of York and beyond, the net seems to be closing around a mysterious gang of killers and a vow of silence that's been kept for two decades. But when a new body is discovered in a local wood, is that pact about to be tested?
