A remarkable object has fallen into the hands of the abominable scientist Sir Giles Tumulty. Once positioned at the center of the crown of King Solomon, it is a stone of astonishing and terrifying power, capable of good and evil alike. Anyone who touches it can move through time and space, perform miracles, and heal or kill. The stone can replicate itself, and does so during the course of Sir Giles's inhuman experiments, subsequently falling into numerous unworthy hands throughout England. There are those who will attempt to use the stone for personal gain, only to discover that it is they themselves being used by a power beyond their comprehension; some will find themselves trapped in eternally repeating nightmares from which there is no escape; still others will be freed from their earthly burdens. And so begins the battle between the forces of darkness and light for control of the most dangerous object in existence. A gripping metaphysical thriller by Charles Williams.
