'Who hath done evil to you?' said the king.
'Sir Caradoc of the Dolorous Tower in the Marsh,' replied the old woman. 'I and my son, lord, did build a little hut of wattle on a little plot which we banked from the marsh, near the great wall of the rich baron, deeming it safe to rest within the shadow of the strong lord, and though his hard rule was hateful to those whom he oppressed, we were so humble that we thought he would not notice us. And meagrely we reared our living from the ground, and sold our poor herbs to Sir Caradoc his steward, or to the people in the villages in the marsh about us. But soon the Lord Caradoc desired the land on which our little hut was standing, to make his lands the broader. He tore our poor home down, and scattered all, and thrust us out to wander in the marshes; and when my poor son pleaded with the lord, he had him whipped, and he was brought and cast half dead at my feet as I waited outside the hall. Now if thou givest us not justice, we shall surely die.'
'Doth any know Sir Caradoc?' asked the king of his knights.
'Yea, sir,' said one, 'and he is a great man of his hands, fierce and bold, of strong family, and his brother is Sir Turquine of Camber, who tried to slay thee at Caerleon, and was with the eleven kings in battle. Sir Caradoc liveth in a strong tower beyond the marshes to the south of the river, and he slayeth all that desire to pass them, unless they pay him all he demands.'
'What!' said the king with fierce anger, 'within a few miles of this my justice-seat doth such tyranny rule unchecked, and ye tell me naught of it? Are ye then more fearful of this marsh robber than of me your king?'
The knights hung their heads abashed, and were silent.
Then Lancelot came and stood before the king.
'Let me, sir king, go and summon this tyrant to your presence,' he said, 'so that this poor dame may have justice, and that ye may punish him for his oppression.'
'I fear me, Lancelot, thou art over young for so fierce a knight,' said Arthur.
'I shall but bear thy words, sir,' said Lancelot, and he will not harm thy messenger.'
