He looked upon the garden and the playing child, and upon the lovely young woman beneath him, but with eyes which did not see, for De Vac was working out a great problem, the greatest of all his life. For three days, the old man had brooded over his grievance, seeking for some means to be revenged upon the King for the insult which Henry had put upon him. Many schemes had presented themselves to his shrewd and cunning mind, but so far all had been rejected as unworthy of the terrible satisfaction which his wounded pride demanded. His fancies had, for the most part, revolved about the unsettled political conditions of Henry’s reign, for from these he felt he might wrest that opportunity which could be turned to his own personal uses and to the harm, and possibly the undoing, of the King. For years an inmate of the palace, and often a listener in the armory when the King played at sword with his friends and favorites, De Vac had heard much which passed between Henry III and his intimates that could well be turned to the King’s harm by a shrewd and resourceful enemy. With all England, he knew the utter contempt in which Henry held the terms of the Magna Charta which he so often violated along with his kingly oath to maintain it. But what all England did not know, De Vac had gleaned from scraps of conversation dropped in the armory: that Henry was even now negotiating with the leaders of foreign mercenaries, and with Louis IX of France, for a sufficient force of knights and men-at-arms to wage a relentless war upon his own barons that he might effectively put a stop to all future interference by them with the royal prerogative of the Plantagenets to misrule England. If he could but learn the details of this plan, thought De Vac: the point of landing of the foreign troops; their numbers; the first point of attack. Ah, would it not be sweet revenge indeed to balk the King in this venture so dear to his heart! A word to De Clare, or De Montfort would bring the barons and their retainers forty thousand strong to overwhelm the King’s forces. And he would let the King know to whom, and for what cause, he was beholden for his defeat and discomfiture. Possibly the barons would depose Henry, and place a new king upon England’s throne, and then De Vac would mock the Plantagenet to his face. Sweet, kind, delectable vengeance, indeed! And the old man licked his thin lips as though to taste the last sweet vestige of some dainty morsel.
