When Damia Miller is employed to promote revered Kineton and Dacre college, it doesn't take her long to recognise that a grotesque antique painting recently uncovered on one of the college's walls might hold the key to the college's future. Six hundred years earlier, master mason Simon of Kineton is preparing plans for his magnum opus, a college to rival anything in England. His work only interrupted when he becomes father to the son he has longed for for twenty years. In the present day, Damia grows increasingly obsessed with the mysterious wall-painting and the college's dark history. What is the painting trying to tell her? Why was the college named after its mason as well as its founder? And who does the statue of the carefree boy in the Toby Yard represent? In mediaeval Salster, Simon of Kinnerton is struggling to come to terms with the fact that his son is disabled - cursed, in the eyes of many of Salster's townspeople. But just as Simon himself is coming to accept young Toby a tragedy occurs whose repercussions will echo until the present day. Testament is a startling feat of imaginative skill, distinguished by the breadth of its vision, and by the heartbreaking story at its centre: that of the sacrifice a child made for his father, six hundred years ago.
