Therewith King Arthur fell to talking of other things with Sir Tristram, but the lady could not join them in talk, but sat thenceforth in silence, finding it hard to breathe because of the oppression of tears that lay upon her bosom.

And Belle Isoult said no more concerning that question that King Arthur had asked. But three days after that time she came to Sir Tristram and said: "Dear lord, I have bethought me much of what King Arthur said, and this hath come of it, that I must return again unto Cornwall."

Then Sir Tristram turned away his face so that she might not see it, and he said, "Methought it would come to that." And then in a little he went away from that place, leaving her standing there.

So it came about that peace was made betwixt Sir Tristram and King Mark, and Belle Isoult and King Mark, and King Arthur was the peacemaker.

Belle Isoult scorns King Mark.

Thereafter Sir Tristram and his court and the Lady Belle Isoult returned unto Cornwall, and there they dwelt for some time in seeming peace. But in that time the Lady Belle Isoult would never see King Mark nor exchange a word with him, but lived entirely apart from him and in her own life in a part of the castle; and at that King Mark was struck with such bitterness of despair that he was like to a demon in torment. For he saw, as it were, a treasure very near and yet afar, for he could not come unto it. And the more he suffered that torment, the more he hated Sir Tristram, for in his suffering it appeared to him that Sir Tristram was the cause of that suffering.

So it came about that King Mark set spies to watch Sir Tristram, for in his evil heart he suspected Sir Tristram of treason, and he hoped that his spies might discover Sir Tristram in some act for which he might be punished. So those spies watched Sir Tristram both night and day, but they could find nothing that he did that was amiss.

Now one day Belle Isoult felt such a longing for Sir Tristram that she could not refrain from sending a note to him beseeching him for to come to her so that they might see one another again; and though Sir Tristram misdoubted what he did, yet he went as she desired, even if it should mean the peril of death to him.

Then came those spies to King Mark and told him that Sir Tristram was gone to the bower of the Lady Belle Isoult, and that she had bidden him to come thither.
