With this they turned and walked away in anger and grief, as Arthur came up.
"What is this?" asked the king. "Is there bad blood between you brethren?"
"They do not care to hear the truth," said Agravaine, "but to my fancy it has been kept too long from your knowledge. We are your sister's sons, King Arthur, and it is our duty to be honest and open with you."
"What would you say?" asked the king.
"Simply what we and all your court know well, that there are such doings between Lancelot and your queen as are a disgrace to this realm of England. He is a traitor to your person and your honor, and this we stand ready to prove."
"This is a perilous charge you make," said Arthur, deeply moved. "Nor am I ready to believe such a tale on your mere word. You have gone far, gentlemen; too far, I deem, without abundant proof."
"My lord," said Mordred, "we speak not without due warrant, and proof you shall have. What we advise is, that you ride out to the hunt to-morrow. Lancelot, you will find, will have some excuse to hold back. Then, when night draws near, send word to the queen that you will lie out all that night. Let this be done, and we promise you we shall take him with the queen. If we do it will go hard with Lancelot; for we shall not lightly see our king brought to shame."
"Be it so," said the king, after deep thought, for he was little inclined to believe ill of Lancelot. "I will do as you say. Understand, sir knights, I have heard all this before; yet I believe it not, and I consent to your scheme only to put an end to the vile voice of scandal."
On the next morning, as agreed upon, Arthur rode to the hunt; but Lancelot excused himself, as his enemies had predicted, on the plea that he was in no mood for the chase. When night came near a messenger from the king brought word to Guenever that the hunting party had been drawn far away, and would not return that night.
Meanwhile Mordred and Agravaine selected twelve knights, all of them enemies of Lancelot, to whom they told their purpose, and set them on guard in the castle of Carlisle, where the court then was. Of Lancelot's friends few were in the court, for nearly all had gone with the king to the hunt.
