Was there a glimmer of real pity and sadness in those wondrous eyes? She laughed--was it a laugh of despair or of exultation?--and hid her face on his bosom. And what was it that awoke in Leopold? Had the drug resumed its power over him? Was it rage at her mockery, or infinite compassion for her despair? Would he slay a demon, or ransom a spirit from hateful bonds? Would he save a woman from disgrace and misery to come? or punish her for the vilest falsehood? Who can tell? for Leopold himself never could. Whatever the feeling was, its own violence erased it from his memory, and left him with a knife in his hand, and Emmeline lying motionless at his feet. It was a knife the Scotch highlanders call a skean-dhu, sharp-pointed as a needle, sharp-edged as a razor, and with one blow of it he had cleft her heart, and she never cried or laughed any more in that body whose charms she had degraded to the vile servitude of her vanity. The next thing he remembered was standing on the edge of the shaft of a deserted coalpit, ready to cast himself down. Whence came the change of resolve, he could not tell, but he threw in his cloak and mask, and fled. The one thought in his miserable brain was his sister. Having murdered one woman, he was fleeing to another for refuge. Helen would save him. How he had found his way to his haven, he had not an idea. Searching the newspapers, Helen heard that a week had elapsed between the "mysterious murder of a young lady in Yorkshire" and the night on which he came to her window. CHAPTER XXVIII. SISTERHOOD. "Well, Poldie, after all I would rather be you than she!" cried Helen indignantly, when she had learned the whole story. It was far from the wisest thing to say, but she meant it, and clasped her brother to her bosom. Straightway the poor fellow began to search for all that man could utter in excuse, nay in justification, not of himself, but of the woman he had murdered, appropriating all the blame. But Helen had recognised in Emmeline the selfishness which is the essential murderer, nor did it render her more lenient towards her that the same moment, with a start of horror, she caught a transient glimpse of the same in herself. But the discovery wrought in the other direction, and the tenderness she now lavished upon Leopold left all his hopes far behind. Her brother's sin had broken wide the feebly-flowing springs of her conscience, and she saw that in idleness and ease and drowsiness of soul, she had been forgetting and neglecting even the being she loved best in the universe. In the rushing confluence of love, truth, and indignation, to atone for years of half-love, half-indifference, as the past now appeared to her, she would have spoiled him terribly, heaping on him caresses and assurances that he was far the less guilty and the more injured of the two; but Leopold's strength was exhausted, and he fell back in a faint.
