It's an incendiary moment for St Oswald's school. For the first time in its history a headmistress is in power, the gates opening to female students. Rebecca Buckfast has spilled blood to reach this position. Barely forty, she is just starting to reap the ambitions she has sown. But as the ground shifts beneath the old guards' feet, a body is discovered, along with a Prefect's badge from another school. But Rebecca is here to make her mark. She'll bury the past, just like she has done before. Even if that means murder.
