For Nicholas Hawthorne, the Catholic heir to Measham Hall in Derbyshire, subterfuge is part of everyday life. But there are deeper and darker secrets even than his family's outlawed religion: why is his father, Sir William, so reclusive? What became of his mother, and his aunt Alethea? And who fatally betrayed his cousin Matthew? Nicholas is determined to find out, but as England slides towards invasion by the Protestant forces of Prince William of Orange, he becomes entangled in conspiracies within King James's court - and soon learns that both truth and love come at a high price.
