The chapel at Maxwell Hall was in the cloister wing; but a stranger visiting the house would never have suspected it. Opening out of Lady Maxwell's new sitting-room was a little lobby or landing, about four yards square, lighted from above; at the further end of it was the door into her bedroom. This lobby was scarcely more than a broad passage; and would attract no attention from any passing through it. The only piece of furniture in it was a great tall old chest as high as a table, that stood against the inner wall beyond which was the long gallery that looked down upon the cloister garden. The lobby appeared to be practically as broad as the two rooms on either side of it; but this was effected by the outer wall being made to bulge a little; and the inner wall being thinner than inside the two living-rooms. The deception was further increased by the two living-rooms being first wainscoted and then hung with thick tapestry; while the lobby was bare. A curious person who should look in the chest would find there only an old dress and a few pieces of stuff. This lobby, however, was the chapel; and through the chest was the entrance to one of the priest's hiding holes, where also the altar-stone and the ornaments and the vestments were kept. The bottom of the chest was in reality hinged in such a way that it would fall, on the proper pressure being applied in two places at once, sufficiently to allow the side of the chest against the wall to be pushed aside, which in turn gave entrance to a little space some two yards long by a yard wide; and here were kept all the necessaries for divine worship; with room besides for a couple of men at least to be hidden away. There was also a way from this hole on to the roof, but it was a difficult and dangerous way; and was only to be used in case of extreme necessity. It was in this lobby that Isabel found herself the next morning kneeling and waiting for mass. She had been awakened by Mistress Margaret shortly before four o'clock and told in a whisper to dress herself in the dark; for it was impossible under the circumstances to tell whether the house was not watched; and a light seen from outside might conceivably cause trouble and disturbance. So she had dressed herself and come down from her room along the passages, so familiar during the day, so sombre and suggestive now in the black morning with but one shaded light placed at the angles. Other figures were stealing along too; but she could not tell who they were in the gloom. Then she had come through the little sitting-room where the scene of last night had taken place and into the lobby beyond. But the whole place was transformed.
