And Sir Tristram was all this while in a turret at the commandment of La Beale Isoud, and when she might she came unto Sir Tristram. So on a day King Mark played at the chess under a chamber window; and at that time Sir Tristram and Sir Kehydius were within the chamber over King Mark, and as it mishapped Sir Tristram found the letter that Kehydius sent unto La Beale Isoud, also he had found the letter that she wrote unto Kehydius, and at that same time La Beale Isoud was in the same chamber. Then Sir Tristram came unto La Beale Isoud and said: Madam, here is a letter that was sent unto you, and here is the letter that ye sent unto him that sent you that letter. Alas, Madam, the good love that I have loved you; and many lands and riches have I forsaken for your love, and now ye are a traitress to me, the which doth me great pain. But as for thee, Sir Kehydius, I brought thee out of Brittany into this country, and thy father, King Howel, I won his lands, howbeit I wedded thy sister Isoud la Blanche Mains for the goodness she did unto me. And yet, as I am true knight, she is a clean maiden for me; but wit thou well, Sir Kehydius, for this falsehood and treason thou hast done me, I will revenge it upon thee.
