"Why should I make another's sin mine? No one can deplore it as I do; but it is not my place to answer for it. I do not understand you, Anna." _She_ did not understand. What did his words mean? "Did you not kill Robert Hunter?" "_I_ kill him! You are dreaming, Anna! I was not near the spot." "Isaac! ISAAC?" "Child! have you been fearing _that?_" "For nothing else, for nothing else could I have shunned you. Oh, Isaac! my dear husband, how could the mistake arise?" "I know not. A mistake it was; I affirm it to you before God. I was not on the plateau at all that night." He opened his arms, gravely smiling, and she passed into them with a great cry. Trembling, moaning, sobbing; Isaac thought she would have fainted. Placing her by his side on the sofa, he kept still, listening to what she had to say. "As I looked out of the Round Tower in the starlight, I caught a momentary glimpse of--as I thought--you, and I saw the hand that held the pistol take aim and fire. I thought it _was_ you, and I fainted. I have thought it ever since. Mary Anne, in a word or two that we spoke together, seemed to confirm it." "Mary Anne knew it was not I. It is not in my nature to draw a pistol on any man. Surely, Anna, you might have trusted me better!" "Oh, what a relief!" she murmured, "what a relief!" then, as a sudden thought seemed to strike her, she turned her face to his and spoke, her voice hushed. "It must have been Richard. You are alike in figure." "Upon that point we had better be silent," he answered, in quite a solemn tone. "It is a thing that we are not called upon to inquire into; let us avoid it. I am innocent: will not that suffice?" "It will more than suffice for me," she answered. "Since that night I have been most wretched." "You need not have feared me in any way, Anna," was the reply of Isaac Thornycroft. "Were it possible that my hand could become stained with the blood of a fellow-creature, I should hasten to separate from you quicker than you could from me. Whatever else such an unhappy man may covet, let him keep clear of wife and children." "Forgive me, Isaac! Forgive me!" "I have not been exempt from the follies of young men, and I related to you the greater portion of my share of them, after we married," he whispered. "But of dark crime I am innocent--as innocent as you are." "Oh, Isaac! my husband, Isaac!" He bent his face on hers, and she lay there quietly, her head nestling in his bosom. It seemed to her like a dream of heaven after the past; a very paradise. "You will forgive me, won't you?" she softly breathed. "My darling!" But paradise cannot last for ever, as you all know; and one of them at any rate found himself very far on this side it ere the night was much older. As Sarah let herself into the house with her back-door key, Isaac quitted it by the front, and bent his steps across the heath.
