After a minute or two, Mistress Margaret touched Isabel on the arm and beckoned to her to come up to the altar, which she began immediately to strip of its ornaments and cloth, having first lit another candle on one of the benches. Isabel helped her in this with a trembling dread, as all the others except Lady Maxwell and her son were now gone out silently; and presently the picture was down, and leaning against the wall; the ornaments and sacred vessels packed away in their box, with the vestments and linen in another. Then together they lifted off the heavy altar stone. Mistress Margaret next laid back the lid of the chest; and put her hands within, and presently Isabel saw the back of the chest fall back, apparently into the wall. Mistress Margaret then beckoned to Isabel to climb into the chest and go through; she did so without much difficulty, and found herself in the little room behind. There was a stool or two and some shelves against the wall, with a plate or two upon them and one or two tools. She received the boxes handed through, and followed Mistress Margaret's instructions as to where to place them; and when all was done, she slipped back again through the chest into the lobby. The priest and his mother were still in their places, motionless. Mistress Margaret closed the chest inside and out, beckoned Isabel into the sitting-room and closed the door behind them. Then she threw her arms round the girl and kissed her again and again. "My own darling," said the nun, with tears in her eyes. "God bless you--your first mass. Oh! I have prayed for this. And you know all our secrets now. Now go to your room, and to bed again. It is only a little after five. You shall see him--James--before he goes. God bless you, my dear!" She watched Isabel down the passage; and then turned back again to where the other two were still kneeling, to make her own thanksgiving. Isabel went to her room as one in a dream. She was soon in bed again, but could not sleep; the vision of that strange worship she had assisted at; the pictorial details of it, the glow of the two candles on the shoulders of the crimson chasuble as the priest bent to kiss the altar or to adore; the bowed head of the server at his side; the picture overhead with the Mother and her downcast eyes, and the radiant Child stepping from her knees to bless the world--all this burned on the darkness. With the least effort of imagination too she could recall the steady murmur of the unfamiliar words; hear the rustle of the silken vestment; the stirrings and breathings of the worshippers in the little room.
