A respected modern historian with a secure job at a red-brick university, father of two in a happy marriage, Tom leads a content and fulfilled life. Then he is arrested. Charged with down-loading child pornography. He is suspended from his post and his wife cannot look him in the eye. He knows he is innocent, but even when he proves he was fifty miles away from his computer when the images were down-loaded he realises he has to find out who set him up before anyone will believe him. But first he has to work out why anyone would want to ruin him. What could he know or do which could be such a threat that someone would maniuplate the legal system against him at the highest level?
