Yseult knew that Alfred loved her, but she did not know of the bitter words which Alfred had spoken to Harold. Her love for Harold was perfect in its trust and gentleness. But Alfred had hit the truth: the curse of old Siegfried was upon Harold—slumbering a century, it had awakened in the blood of the grandson, and Harold knew the curse that was upon him, and it was this that seemed to stand between him and Yseult. But love is stronger than all else, and Harold loved.
Harold did not tell Yseult of the curse that was upon him, for he feared that she would not love him if she knew. Whensoever he felt the fire of the curse burning in his veins he would say to her, "To-morrow I hunt the wild boar in the uttermost forest," or, "Next week I go stag-stalking among the distant northern hills." Even so it was that he ever made good excuse for his absence, and Yseult thought no evil things, for she was trustful; ay, though he went many times away and was long gone, Yseult suspected no wrong. So none beheld Harold when the curse was upon him in its violence.
Alfred alone bethought himself of evil things. "'T is passing strange," quoth he, "that ever and anon this gallant lover should quit our company and betake himself whither none knoweth. In sooth 't will be well to have an eye on old Siegfried's grandson."
Harold knew that Alfred watched him zealously, and he was tormented by a constant fear that Alfred would discover the curse that was on him; but what gave him greater anguish was the fear that mayhap at some moment when he was in Yseult's presence, the curse would seize upon him and cause him to do great evil unto her, whereby she would be destroyed or her love for him would be undone forever. So Harold lived in terror, feeling that his love was hopeless, yet knowing not how to combat it.
Now, it befell in those times that the country round about was ravaged of a werewolf, a creature that was feared by all men howe'er so valorous. This werewolf was by day a man, but by night a wolf given to ravage and to slaughter, and having a charmed life against which no human agency availed aught. Wheresoever he went he attacked and devoured mankind, spreading terror and desolation round about, and the dream-readers said that the earth would not be freed from the werewolf until some man offered himself a voluntary sacrifice to the monster's rage.
Now, although Harold was known far and wide as a mighty huntsman, he had never set forth to hunt the werewolf, and, strange enow, the werewolf never ravaged the domain while Harold was therein. Whereat Alfred marvelled much, and oftentimes he said: "Our Harold is a wondrous huntsman. Who is like unto him in stalking the timid doe and in crippling the fleeing boar? But how passing well doth he time his absence from the haunts of the werewolf. Such valor beseemeth our young Siegfried."
Which being brought to Harold his heart flamed with anger, but he made no answer, lest he should betray the truth he feared.
It happened so about that time that Yseult said to Harold, "Wilt thou go with me to-morrow even to the feast in the sacred grove?"
"That can I not do," answered Harold. "I am privily summoned hence to Normandy upon a mission of which I shall some time tell thee. And I pray thee, on thy love for me, go not to the feast in the sacred grove without me."
"What say'st thou?" cried Yseult. "Shall I not go to the feast of Ste. Aelfreda? My father would be sore displeased were I not there with the other maidens. 'T were greatest pity that I should despite his love thus."
