Cornwall is a fascinating domain. Here, Celtic mythology melded Christianity with an earlier faith. Moreover, the Cornish are a musical people. A young lady violinist is brought into supernatural contact with a Queen from another universe. This Queen (Catharine) is a lineal descendant of Guinever, the wife of King Arthur, and a contemporary of Morgan le Fey - a Queen who helped to transport the injured Arthur to be healed in the island of Avalon. The story is a fast-moving construction focusing on the Spear of Joseph of Arimathea who brought it to what is now England, at the same time as the Holy Grail. The Spear has enormous psychic power, which can be used for good or ill as its owner desires. Centuries later, the Spear becomes located in the sealed crypt of a Cornish church, where evil men seek to force entry. They are foiled by a small band of people, including a violinist, Jennifer Parsloe, and a student, Arthur Marazion. Numerous adventures follow, including transference through time and space.
