The book covers a two-week period in November 1120, beginning with the death of King Brion Haldane while leading a hunting party outside the city of Rhemuth. Immediately following Brion's death, his son and heir, Prince Kelson sends for his father's closest friend and advisor, Alaric Morgan, the Deryni Duke of Corwyn. Morgan arrives shortly before Kelson's coronation, but his efforts to assist the prince are interrupted by Kelson's mother, Queen Jehana. However, Kelson manages to thwart Jehana's attempts to imprison Morgan, and the duke resumes his efforts to protect Kelson.
