Not until I heard him speak, did it rush upon me that I had no business to be there, spying and eavesdropping. I had looked at first, unconscious of the circumstances, like a wandering spirit lingering by the walls of Eden, gazing upon the beauty which is not within its sphere. No sooner did I realize my position than I began to descend from my eyrie; but James had drawn his cousin from her chair, and the pair approached the window, and stood there, their eyes fixed, apparently, upon that very point in the giant oak where I crouched, suddenly fear-blasted, with the square of light from the window illuminating the limb where I lay concealed. I had crawled from my first resting-place, and was about jumping to the ground, when their presence transfixed me, in the most dangerous possible predicament. I dared not move for fear of being discovered. I was paralyzed by a lightning consciousness that should I then and there be betrayed, I would be the victim of a singular combination of _circumstantial evidence_. Found lingering at night, like a thief, upon the premises of those I had injured; stealthily seeking to remove the evidence of my guilt--the weapon with which the murder was committed, hidden by me, at the time, in this tree, and now sought for in order to remove it from possible discovery--why, I tell you, reader, had James Argyll sprung upon me there, seized the knife, accused me, nothing would have saved me from condemnation. The probabilities are, that the case would have been so very conclusive, and the guilt so horribly aggravated, that the populace would have taken the matter in their own hands, and torn me to pieces, to show their love of justice. Even the testimony of Mr. Burton would not have availed to turn the tide in my favor; he would have been accused of seeking to hide my sin, and his reputation would not have saved him from the ban of public opinion. A cold sweat broke over me as I thought of it. Not the fear of death, nor of the horror of the world--but dread of the judgment of the two sisters took possession of me. If this statement of my critical position, when the trembling of a bough might convict an innocent man, should make my reader more thoughtful in the matter of circumstantial evidence, I shall be repaid for the pangs which I then endured. The young couple stepped out upon the sward. I did not trouble myself about what had become of Mr. Burton, for I knew that he was in the shadow, and could retreat with safety; he, doubtless, felt more anxiety about me. "Draw your scarf up over your head, Mary," said James, in that soft, pleasant voice of his, which made me burn with dislike as I heard it--"the night is so warm, it will not harm you to be out a few moments. Do not deny me a little interval of happiness to-night."
