England in the summer of 1436. The King's mother Katherine of Valois, send her two little sons Edmund and Jasper (aged six and five) to safety in Wales from evil and ambitious men who want them out of the way. They are waylaid by thugs and must take refuge. with five members of their household, in St Fridewides Abby, where they are put under Dame Frevisse's protection, as Dame Frevisse is unable to turn away children. They become friends with a charge of the abbey of their own age, the Lady Adela. A series of mishaps followed by two murders leads Dame Frevisse to suspect evil is afoot in the Abbey and someone has infiltrated the sanctuary to try to harm the young princes. Another medieval murder mystery unravels. English history aficionados will find it of interest that the older of the two boys is Edmund Tudor, who will sire Henry VII, and therefore be an ancestor to all subsequent English monarchs. The author does well in capturing the sights, sounds, smells and culture of 15th century England.
