As a member of the Order of the Round Table, Kendall Lake is overqualified to be investigating strange phenomena at a seaside photography studio. But since the photographer is related to the Order's most powerful sorcerer, Kendall reluctantly boards a dirigible to Brighton. Amy Deland is haunted by a shadow that appears in some of her recent portraits. In each case, the subject died within days of the sitting. Does she have her grandmother's gift of foresight, or has she somehow caused the deaths? As Kendall and Amy search for answers, their investigation draws them together in a most improper way but it seems the evil presence in the studio is determined to keep them apart.
