Her mind was occupied with various problems. First and foremost, she was extremely anxious to ascertain how much money the man she called her husband actually had, where it was, and how it could be got at, say by one who had a right to get at it. Almost as if he were conscious of what was transpiring in her brain, Cuthbert Grahame took advantage of an opportunity which arose, or which he, perhaps, made himself, to volunteer some information on the subject on his own account. The afternoon on which the conversation took place would have been memorable for something else, even if he had not seen fit to make her the receptacle of some very interesting confidences. Isabel was an active young woman; healthy, full-blooded, vigorous, one in whose veins the blood ran strong. Inaction to her was punishment. So soon as her ankle permitted, and it proceeded to a rapid and complete recovery, she spent a portion of each day in taking the air--that portion of the day which was not spent in prying into everything the house contained. As her researches drew to a conclusion--as even the most thorough investigation allowed them to do in time--that unoccupied portion became more and more. So, having examined the inside of the house she turned her attention to the outside, to learn that her husband's estate was of considerable extent. She wandered up and down it, to and fro, till she began to be almost as intimately acquainted with it as with the contents of the residence. One afternoon she was indulging in one of these rambles when she received what really amounted to a shock. She was passing through one of the woods of which her husband's property seemed chiefly to consist, and was resting on the bole of a tree, when she heard the sound of wheels. She was perhaps in a peculiar mood, because it immediately brought back to her that night on which she had listened--with what an anxious heart!--to the wheels of Dr. Twelves' approaching trap. Passers-by, thereabouts, were few and far between; for days together she would not encounter any. She had grown to love seclusion, possibly for sufficient reasons of her own. She was seated on a slope. The road began at the foot, perhaps thirty feet away. She instinctively altered her position, so that, while she could see herself, the trunk of the tree almost entirely screened her from observation. She wondered who was coming, peeping round to see. When she did see she drew back with a start.
