Written about the 1970s, the Glass Class is set partly in Pennine Yorkshire, North Wales, Athens and finally on the Greek island of Spetses where a group of friends approaching middleage are forced to confront that their mortality. Marriages are fraying, children have become more noticeable and alcohol for some is perhaps consumed more lavishly. When death is introduced into this toxic mix not once, but three times no wonder their cozy life is shattered. The characters, journalists, industrialists, doctors are struggling to keep their day to day life in order. They regularly take their concerns on holiday whether it is walking in Snowdonia or to the apparent safety of a Greek island. Between the scenes of a thriller and crime story is romance and a historical perspective introduced by a family tree. The stories of ancestral lore dating to the Victorian and Edwardian eras and told by their elders as cautionary tales. What none of them can know is that the clue they need to solve far too many deaths within their circle is here in their family tree.
