He snatched the letter from his hand--changed colour as he looked on the superscription--undid with faltering hand the knot which secured it--glanced over the contents, and staggering back, would have fallen, had he not rested against the trunk of a tree, where he stood for an instant, his eyes bent on the letter, and his sword-point turned to the ground, without seeming to be conscious of the presence of an antagonist towards whom he had shown little mercy, and who might in turn have taken him at advantage.

But for such revenge Tressilian was too noble-minded.

He also stood still in surprise, waiting the issue of this strange fit of passion, but holding his weapon ready to defend himself in case of need against some new and sudden attack on the part of Leicester, whom he again suspected to be under the influence of actual frenzy.

The boy, indeed, he easily recognized as his old acquaintance Dickon, whose face, once seen, was scarcely to be forgotten; but how he came hither at so critical a moment, why his interference was so energetic, and, above all, how it came to produce so powerful an effect upon Leicester, were questions which he could not solve.
But the letter was of itself powerful enough to work effects yet more wonderful.

It was that which the unfortunate Amy had written to her husband, in which she alleged the reasons and manner of her flight from Cumnor Place, informed him of her having made her way to Kenilworth to enjoy his protection, and mentioned the circumstances which had compelled her to take refuge in Tressilian's apartment, earnestly requesting he would, without delay, assign her a more suitable asylum.
The letter concluded with the most earnest expressions of devoted attachment and submission to his will in all things, and particularly respecting her situation and place of residence, conjuring him only that she might not be placed under the guardianship or restraint of Varney.
The letter dropped from Leicester's hand when he had perused it.
