There was no difficulty now as to the way. She knew it, every stair. At the head of each flight she stood and listened, but not a sound was to be heard, and then she went on again. Her heart beat high with anxious desire to achieve her object, and at the same time with fear. What might [Illustration] have been explained so easily at first would now be as difficult of explanation, At last she was in the great public vestibule, which she was now visiting for the third time, and of which, at her last visit, she had taken the bearings accurately. The door was there--closed, indeed, but it opened f to the hand, the hall and on e stairs and o n g the passages there had been gas, but here there was no light beyond that given by the little taper which she carried. When accompanied by the porter she had not feared the darkness, but now there was something in the obscurity which made her dread to walk the length of the room up to the mustard jar. She paused, and listened, and trembled. Then she thought of the glories of Thompson Hall, of the genial warmth of a British Christmas, of that proud legislator who was her first cousin, and with a rush she made good the distance, and laid her hand upon the copious delf. She looked round, but there was no one there; no sound was heard; not the distant creak of a shoe, not a rattle from one of those thousand doors. As she paused with her fair hand upon the top of the jar, while the other held the white cloth on which the medicinal compound was to be placed, she looked like Lady Macbeth as she listened at Duncan’s chamber door. There was no doubt as to the sufficiency of the contents. The jar was full nearly up to the lips. The mixture was, no doubt, very different from that good, wholesome English mustard which your cook makes fresh for you, with a little water, in two minutes. It was impregnated with a sour odor, and was, to English eyes, unwholesome of color. But still it was mustard. She seized the horn spoon, and without further delay spread an ample sufficiency on the folded square of the handkerchief. Then she commenced to hurry her return. But still there was a difficulty, no thought of which had occurred to her before. The candle occupied one hand, so that she had but the other for the sustenance of her treasure. Had she brought a plate or saucer from the salon, it would have been all well. As it was, she was obliged to keep her eye intent on her right hand, and to proceed very slowly on her return journey. She was surprised to find what an aptitude the thing had to slip from her grasp. But still she progressed slowly, and was careful not to miss a turning. At last she was safe at her chamber door. There it was, No. 333. CHAPTER II. MRS. BROWN’S FAILURE.
