"Nay," answered Hugo. "I know not. I have never before thought of the postern and its key." The traitor's frowning face cleared. "I believe thou speakest truly," he said. "Thou art so full of being a knight that thou thinkest only of knightly exercises in the tilt-yard. I will speak a good word for thee, and it may be thou wilt be admitted a page to the Earl of Hertford." "And hast thou influence there?" inquired Hugo, with assumed interest. "Yea, that have I," answered Robert Sadler, falsely. For he had no influence anywhere. "I will so speak for thee that thou wilt be page but a short while before thou art made an esquire. Do thou but bide quiet concerning what hath passed between us, and thou shalt fare never the worse." Then he departed to the stables and Hugo was left alone. To be able to conceal what one feels is a great accomplishment. Rarely do people of any age succeed in doing so, and it was with a feeling of exultation over his success that the boy looked after Robert Sadler. The next day Lady De Aldithely summoned her men-at-arms before her in the castle hall. She had a missive in her hand. "I must send one of you on a journey," she said. "More than one I cannot now spare to go to Chester. Who will take this missive from me to the town of Chester, and bring back from my aunt what it calleth for?" A light flashed in the eyes of Robert Sadler which Lady De Aldithely affected not to see. The opportunity he had been seeking was before him. He would go out alone, but he would not return alone. When the drawbridge should be lowered to admit him on his return the king's messengers with a troop of horse would be at hand. They would make a rush while he held parley with the old warder. They would gain entrance to the castle; Josceline would be taken, and the reward for his own treachery would be gained. He had plenty of time to think of all this, for the men were slow to offer. Aside from Robert Sadler they were all true and devoted adherents of the De Aldithelys, and each one imagined the castle and its inmates safer because of his presence. Therefore none desired to go. "No man seemeth willing to do thy ladyship's behest," said Robert Sadler, with a crafty smile. "I will, by thy leave, undertake it." Lady De Aldithely looked calmly upon him. "Thou shalt do so, Robert Sadler," she said courteously, "and thou hast my thanks for the service. Thou shalt depart to-morrow morn, and thou shouldest return by the evening of this day week. See that thou bringest safely with thee what the missive calleth for." "I will return at eventide of this day week," promised the traitor as he received the missive. "And now," he said to himself, when Lady De Aldithely had retired from the hall, "let her keep the postern key. I care not for it." CHAPTER III It was now mid-June. The air was dry and cool. But Robert Sadler thought not of June nor dryness and coolness of air as in triumph he made ready for his journey.
