And when King Mark had agreed, this dwarf did a vile thing. He bought of a baker four farthings' worth of flour, and hid it in the turn of his coat. That night, when the King had supped and the men-at-arms lay down to sleep in hall, Tristan came to the King as custom was, and the King said: "Fair nephew, do my will: ride to-morrow night to King Arthur at Carduel, and give him this brief, with my greeting, that he may open it: and stay you with him but one day."
And when Tristan said: "I will take it on the morrow;"
The King added: "Aye, and before day dawn."
But, as the peers slept all round the King their lord, that night, a mad thought took Tristan that, before he rode, he knew not for how long, before dawn he would say a last word to the Queen. And there was a spear length in the darkness between them. Now the dwarf slept with the rest in the King's chamber, and when he thought that all slept he rose and scattered the flour silently in the spear length that lay between Tristan and the Queen; but Tristan watched and saw him, and said to himself: "It is to mark my footsteps, but there shall be no marks to show."
At midnight, when all was dark in the room, no candle nor any lamp glimmering, the King went out silently by the door and with him the dwarf. Then Tristan rose in the darkness and judged the spear length and leapt the space between, for his farewell. But that day in the hunt a boar had wounded him in the leg, and in this effort the wound bled. He did not feel it or see it in the darkness, but the blood dripped upon the couches and the flour strewn between; and outside in the moonlight the dwarf read the heavens and knew what had been done and he cried: "Enter, my King, and if you do not hold them, hang me high."
Then the King and the dwarf and the four felons ran in with lights and noise, and though Tristan had regained his place there was the blood for witness, and though Iseult feigned sleep, and Perinis too, who lay at Tristan's feet, yet there was the blood for witness. And the King looked in silence at the blood where it lay upon the bed and the boards and trampled into the flour.
And the four barons held Tristan down upon his bed and mocked the Queen also, promising her full justice; and they bared and showed the wound whence the blood flowed.
