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.
