‘If you can doubt me, I have no more to say,’ said the young man; and then they started apart, and the briefest lovers’ quarrel ensued--a quarrel soon made up in the inevitable, universal way, strengthening the position of the one who attacked, and weakening that of the defender. Stapylton drew Isabel’s hand through his arm when she gave it him in reconciliation and led her through the heather farther and farther from home. ‘You are never to utter such cruel words any more,’ he said, ‘nor so much as to think them. Am not I ready to give up everything for you? The old Hall, and my father’s favour, and all I might have if I pleased. It is different from Loch Diarmid, Isabel; but I care for nothing but you; and you will not make the least little sacrifice for me.’ ‘I would make any sacrifice--any sacrifice; there is nothing so hard but I would try to do it--for you, Horace,’ said the girl with tears. ‘And yet you will not come away with me for two or three days, and be made my wife! What are you afraid of, Isabel? Can you not trust me? Do you think I would harm you? Tell me what it is you fear?’ ‘Fear!’ said Isabel surprised, lifting her eyes to his face. ‘When you are with me what can I fear?’ ‘Then why don’t you trust me?’ said the young fellow, with a sudden flush on his face. ‘I trust you as I trust myself,’ said Isabel. ‘Could I care for anyone as I care for you, and not trust him? It is my own folk I am thinking of. I cannot deceive my own folk. Oh, dinna ask me, Horace, and I will do anything else in the world.’ ‘Your own folk!’ said Horace, with a little contempt; ‘Jean Campbell, perhaps, that is not good enough to be your housekeeper. I am deceiving father and mother for you, Isabel, and I never grumble. To think of your father’s widow in comparison with me!’ ‘I think of Margaret,’ said Isabel, ‘my twin sister. Oh, never ask me more! It would kill my Margaret. Me to deceive her that has been part of herself. Oh, Horace, dinna ask me! I would die to please you; but not even to please you, would I hurt her. I canna do it. I would sooner die!’ Young Stapylton’s face grew red all over with a passionate, furious colour: then he drew his breath hard and restrained himself. For one moment he grasped Isabel’s hand, which rested on his arm, with a firm pressure, which would have made her scream had she been less startled. Then he loosed it with a strange little laugh which was not pleasant to hear.
