Desire and power collide in the court of Elizabeth I Warwickshire, 1575. Pomp, fanfare and a wealth of lavish festivities await Elizabeth I at Kenilworth Castle. Organised by the Earl of Leicester, he knows this celebration is his last chance to persuade the Queen to marry him. But, a fickle man, he is unable to resist the seductive wiles of Lettice Knollys. Enraged by the couple's growing intimacy, Elizabeth employs a young black singer and court entertainer to keep a watch on them. Brought up by a spy, Lucy's observational skills are sharper than anyone at the castle realises, and she soon uncovers far more than she bargained for: someone at Kenilworth is plotting to kill the queen. Can the knowledge Lucy is gaining prevent the death of the monarch? Or has it put Lucy in mortal danger instead?
