For some reason this seemed to relieve him. He hung up his hat and stood pulling at his fingers until the joints cracked, which was a trick with him. "She needs to be soothed," he said. "If you read much with her, you must come to me to choose the books; yet she must think she has chosen them herself. We must manage that somehow. The great thing is to keep her mind soothed." Kirstie did not understand. A few minutes later as she went up the stairs to her room the door opposite still remained open. All was dark within, but whether or not Mrs. Johnstone sat there in the darkness she could not tell. The next morning she entered on her duties, which were light enough. Indeed, she soon suspected that her mistress had sought a companion rather than a servant, and at first had much to-do to find employment. Soon, however, Mrs. Johnstone took her into confidence, and began to impart the mysteries of whitening and twisting the famous Balgarnock thread; and so by degrees, without much talk on either side, there grew a strange affection betwixt them. Sure, Kirstie must have been the first of her sex to whom the strange woman showed any softness; and on her part the girl asserts that she was attracted from the first by a sort of pity, without well knowing for what her pity was demanded. The minister went no farther with his confidences: he could see that Kirstie suited, and seemed resolved to let well alone. The wife never spoke of herself; and albeit, if Kirstie's reading happened to touch on the sources of Christian consolation, she showed some eagerness in discussing them, it was done without any personal or particular reference. Yet, even in those days, Kirstie grew to feel that terror was in some way the secret of her mistress's strangeness; that for the present the poor woman knew herself safe and protected from it, but also that there was ever a danger of that barrier falling--whatever it might be--and leaving her exposed to some enemy, from the thought of whom her soul shrank.
