"I have marked his walk and carriage closely, my lord. He steps along with a long stride, and unless he be a better mummer than I judge him to be, I should know him whether in a monk's gown or a servitor's cloak. It is no easy thing to change a knight's stride into the shuffle of a sandalled monk, or the noiseless step of a well-trained servitor in a bishop's palace."

"You are a shrewd lad indeed, Ulf," Wulf said warmly; "and I feel that you will fathom this matter if there be aught at the bottom. But, as you say, you cannot watch more than one place."

"The other entrance is not altogether unwatched, my lord. The first day you gave me my orders I went to one of my cronies, who has shared with me in many an expedition when our master deemed that we were soundly asleep. Without, as you may be sure, giving any reason, I told him that I had come to believe that the Norman I pointed out to him was in the habit of going out in disguise, and that I was mightily curious to find whither he went and why, and therefore wanted him to watch, at the entrance behind the palace. I bade him mark the walk of the persons that went out, and their height, for the Norman is tall, and to follow any who might come out of lofty stature, and with a walk and carriage that seemed to accord ill with his appearance. So each evening, as soon as his house was closed and the lights extinguished, he has slipped out, as he knows how, and has watched till ten o'clock at the gate. It seemed to me that that would be late enough, and indeed the doors are closed at that hour."
