Of this her friend knew nothing, for he sought his delight in the hall, at carol and dance and play.  But amongst all those ladies he had no pleasure in any that he saw, since he might not perceive her to whom his heart was given, and much he marvelled thereat.  He took the Duke apart, and said in his ear,

“Sire, whence is this that your niece tarries so long, and comes not to the dancing?  Have you put her in prison?”

The Duke looked upon the dancers, for he had not concerned himself with the revels.  He took his friend by the hand, and led him directly to his wife’s chamber.  When he might not find her there he bade the knight seek her boldly in the tiring chamber; and this he did of his courtesy that these two lovers might solace themselves with clasp and kiss.  The knight thanked his lord sweetly, and entered softly in the chamber, where his friend lay dark and discoloured upon the bed.  Time and place being met together, he took her in his arms and touched her lips.  But when he found how cold was her mouth, how pale and rigid her person, he knew by the semblance of all her body that she was quite dead.  In his amazement he cried out swiftly,

“What is this?  Alas, is my dear one dead?”

The maiden started from the foot of the bed where she still lay, making answer,

“Sir, I deem truly that she be dead.  Since she came to this room she has done nothing but call upon death, by reason of her friend’s falsehood, whereof my lady assured her, and because of a little dog, whereof my lady made her jest.  This sorrow brought her to her death.”

When the knight understood from this that the words he had spoken to the Duke had slain his friend, he was discomforted beyond measure.

“Alas,” said he, “sweet love, the most gracious and the best that ever knight had, loyal and true, how have I slain you, like the faithless traitor that I am!  It were only just that I should receive the wages for my deed, so that you could have gone free of blame.  But you were so faithful of heart that you took it on yourself to pay the price.  Then I will do justice on myself for the treason I have wrought.”

The knight drew from its sheath a sword that was hanging from the wall, and thrust it throught his heart.  He pained himself to fall upon his lady’s body; and because of the mightiness of his hurt, bled swiftly to death.  The maiden fled forth from the chamber, when she marked these lifeless lovers, for she was all adread at what she saw.  She lighted on the Duke, and told him all that she had heard and seen, keeping back nothing.  She showed him the beginning of the matter, and also of the little dog, whereof the Duchess had spoken.
