THERE ARE MORE THAN JUST SECRETS BURIED IN THESE WALLS It's the day of the demolition at White Cross Academy, and a crowd of former pupils and teachers have gathered to watch. But as the final charges are laid in the basement, the crew make a shocking discovery - a human skull. Former student DI Jennie Whitmore is assigned to the case, her first big murder investigation and one where there can be no room for mistakes. The remains are identified as Hannah Jennings, a popular, but troubled classmate who went missing during her lower Sixth year. As news of the body's discovery soon leaks, the small town erupts with intrigue, conspiracy and accusation. Jennie now finds herself at the heart of the storm, tasked with making up for the failings of the initial investigation to ensure that justice is finally done. At the centre is Hannah's five closest friends who used the basement as a base for the photography club. Jennie knows many of the suspects personally and she is convinced that one of this group of five knows the truth about what happened to the wilful, beguiling teenager. As Jennie unearths secrets buried deep, and lies repeatedly told, the assembled friends must reassess their past, before confronting the terrible realisation that one amongst them would rather kill to protect their new life, than pay for the sins of their teenage years.
