Fleeing expulsion and the death of a close friend, Andrew Taylor is sent to spend his final year at the prestigious public school Harrow. It is an eccentric place, a rambling ancient building filled with the sons of the rich and famous. The other pupils notice Andrew's striking resemblance to Lord Byron, a former pupil of Harrow - and then the trouble begins. Andrew senses a malevolent presence, and when a classmate dies, the haunting becomes all too real. When another classmate falls ill, and Andrew discovers old letters hidden in a bricked-up basement, he must uncover a secret history - before it is too late.
