But Sir Launcelot bade ever Sir Tristram beware of King Mark, for ever he called him in his letters King Fox, as who saith, he fareth all with wiles and treason.

Whereof Sir Tristram in his heart thanked Sir Launcelot.

Then the damosel went unto La Beale Isoud, and bare her letters from the king and from Sir Launcelot, whereof she was in passing great joy.

Fair damosel, said La Beale Isoud, how fareth my Lord Arthur, and the Queen Guenever, and the noble knight, Sir Launcelot?
She answered, and to make short tale: Much the better that ye and Sir Tristram be in joy.

God reward them, said La Beale Isoud, for Sir Tristram suffereth great pain for me, and I for him.
So the damosel departed, and brought letters to King Mark.
