She took from her pocket a ball of thin string, one end of which was attached to a tiny brad awl. Going into one corner of the room she fixed the brad awl into the woodwork; then, unwinding the ball, proceeded to the other end of the room, straining the string tightly, and tied a knot to mark the length. Then she went back and crossed the room, and again make a knot to mark the width. Then she hastily gathered up the string, pulled the brad awl from the woodwork, and put them in her pocket. While she had been carrying this out she retained a duster in one hand, and dusted the wood work as she moved along, trusting that if Miss Penfold should look in, the string, which was of a dark color, would be unnoticed by her. However she gave a sigh of relief when the operation was complete, and the string and brad awl hidden away. She then continued her work until in about three-quarters of an hour Miss Penfold again appeared.
"I think that will do very well, Anna; it is quite impossible to get all the dust out of the carving. It would take you all day to go over it, and you would need steps for the upper part. That need only be done occasionally." She gave an approving glance round as she noticed that the new housemaid had carefully placed every article in the exact place in which she had found it. Mrs. Conway gathered up the brooms and dusters and left the room, Miss Penfold carefully locking the door after her.
"That is something done," Mrs. Conway said to herself; "and will, I think, save me an immense deal of trouble. To-morrow I will measure the rooms next to it. The passage runs along the side and it is hardly possible that there can be any receptacle there; the wall is not thick enough for a place of any size. It must be at one end or the other, or else under the floor."
The following morning she measured the dining-room, and what was now known as the housekeeper's room, but which in years gone by had been called the still room; and the following day slipped out of doors as soon as she came downstairs and took the outside measurement of the side of the house, marking on the string the position and width of each window. She had only now to make a plan and compare the figures. She found that between the back of the bookcase—for she had taken out a few books to ascertain its depth—and the panel of the dining-room there was a thickness of two feet; but between the library and the housekeeper's room there were fully five feet unaccounted for.
In both were deep old-fashioned fireplaces back to back; and even allowing but six inches between these, the depth there would be accounted for, but on either side of the fireplaces there would be a wide space. There were certainly no cupboards visible in the library, for the bookcases extended from the fireplace to the wall on each side. In the housekeeper's room there were cupboards on each side of the chimney-piece, but these were shallow, not being above nine inches in depth; therefore behind these there was a considerable space unaccounted for. It was evident to Mrs. Conway that her first search must lie in this direction. Here might lie two chambers each three feet wide by eight feet long.
Mrs. Conway's spirits rose at this discovery, and she sighed impatiently at the thought that another month must elapse before she could even commence the search. Brooding over the matter continually, there was one point that did not escape her. These old hiding-places were made either to conceal proscribed priests or hunted fugitives, and were constructed with the greatest care. As she had so easily discovered the spot where a hidden room might be situated, it would be discovered with the same ease by those who were on the search for fugitives, and who would naturally be well acquainted with the positions where hiding-places would be likely to be situated. The moment they looked into the cupboard, its shallowness would suggest to them that there must be a wide empty space behind it, and by setting to work with axes, picks, and crowbars, they would soon discover by force the secret she was trying to penetrate by stratagem.
This reflection considerably damped her hopes; but she thought that possibly from this easily-discoverable hiding-place there might be some access, much more difficult to trace, to another lying below. At any rate she determined that if she did find the secret entrance to these little rooms, and found that they were empty she would not be disheartened, but would search further until she found either some secret closet where the will might be placed, or an entrance to some perhaps larger hiding-place below. Her subsequent search outside showed her that there existed several small iron gratings about six inches long and three deep, close down to the soil of the border. No doubt these were intended to give ventilation underneath the floors, which were some two feet above the outside level, but one of them might also afford ventilation to an underground chamber.
Three months passed, and on the occasion of each of her visits to the room she devoted some time to the examination of the carved woodwork round the fireplace and that of the bookcases, but without making any discovery whatever; and it became evident to her that a far closer search would be needed than the short and hasty examination that was all she dared to make, with the possibility that at any moment Miss Penfold might appear at the door. Accordingly she wrote to Mr. Tallboys, and told him that it would be necessary for her to obtain a cake of very soft wax, four inches long and two inches wide, and asked him to procure it for her, and to send it in a wooden box to her by the carrier's cart that once a week journeyed from Weymouth to the villages in the neighborhood of the Hall.
Ten days later she received the wax, and the next time the day for cleaning the library arrived she quietly withdrew the key from the door as soon as Miss Penfold had left her, laid it on the wax, and pressed it steadily until a deep impression was made upon its surface. Then she carefully examined the key to see that no particle of wax had stuck between the wards, replaced it in the door, closed the lid of the little box in which the wax lay, and put it in her pocket, and then set to at her work of cleaning.
Upon this occasion she spent no time in trying to find the spring. There was danger now as always of Miss Penfold's coming, and as she would soon have the means of entering the room at her will she would run no risk. A few days later she asked for a day to go to Weymouth to purchase some things of which she had need, and when there she called upon Mr. Tallboys.
