Nevertheless I will hold myself on my guard.

I will, so far as possible, avoid any snare which he may, as 'tis not unlikely, set for my life, and will, so far as I honourably can, avoid any quarrel with which he may seek to saddle me." A few days later Walter again met Sir James Carnegie in the king's anteroom, and saw at once, by the fixed look of hate with which he had regarded him, that he had already satisfied himself of his identity.
He returned the knight's stare with a cold look of contempt.

The knight moved towards him, and in a low tone said, "Beware, young sir, I have a heavy reckoning against you, and James Carnegie never forgets debts of that kind!" "I am warned, Sir James," Walter said calmly, but in the same low tone, "and, believe me, I hold but very lightly the threats of one who does not succeed even when he conspires against the lives of women and children." Sir James started as if he had been struck.

Then, with a great effort he recovered his composure, and, repeating the word "Beware!" walked across to the other side of the chamber.

The next day Walter went down the river and had a talk with his friend Geoffrey.
"You must beware, lad," the armourer said when he told him of the return of Sir James Carnegie and the conversation which had taken place between them.
