Cerdic, a young boy who has the ability to see into the future, has a mysterious treasure in his possession. A blind old woman once gave him a miniature knife with an ivory bear hilt - the symbol of King Arthur - and told him that when the time comes he will know what he has to do with it. But when he and his brother, Baradoc, are enlisted into King Arthur's army, he finds that trouble seems to follow him wherever he goes. When Baradoc dies fighting with King Arthur in an ambush of the Saxons on Solsbury Hill, Cerdic buries the dagger in the side of the hill as a personal tribute to his brother.
Throughout history, Solsbury Hill continues to be the scene of murder, theft and the search for buried treasure. Religion, politics and the spirit of King Arthur reign over the region, wreaking havoc and leaving a trail of corpses and treasure buried in the hill as an indication of its turbulent past.
