She thought thus on her way upstairs, carrying a dress of Lady Henry’s, from which she had been brushing the marks of a muddy carriage-wheel. She laid it on a chair, and saw on another a milliner’s box. Her mistress had not mentioned that she was expecting anything, and Joan’s curiosity was aroused. She untied the fastenings, lifted a layer of tissue paper, and saw a neat, dark green tailor-dress, with a toque made of the same material and a little velvet. There was also a long, plain coat of the green cloth, with gold buttons, and on the breast pocket was embroidered an odd design in gold thread. Joan suddenly became thoughtful. This dress was as unlike as possible to the butterfly style which Lady Henry affected, and all who knew her knew that she detested dark colours. Yet this costume was distinctly sombre and severe; and the name of the milliner was unfamiliar to Joan. "It’s like a disguise," the girl said to herself, "and I’ll bet anything that’s what it’s for. She went to a strange milliner; she made a point of the things being ready to-night; she chose a costume which would absolutely change her appearance, if worn with a thick veil. And then that bit of embroidery on the pocket! Why, it’s a miniature copy of the design they print under the title of _The Beacon_. It is a beacon, flaming! She means to slip out of the house when she’s got the secret safe, and somebody at the office of the paper will have been ordered to take a veiled woman with such a dress as this up to Portheous’ private office, without her speaking a word. Well--a woman will go there, but I hope it won’t be Lady Henry." Without stopping for an instant’s further reflection, Joan caught up the box and flew with it to her own room, where she pushed it under the bed. She then watched her chance, and when no one was in sight, darted into the boudoir, where she squeezed herself behind a screen close to the door. She might have found a more convenient hiding-place, but this, though uncomfortable, gave her an advantage. If the two persons she expected to enter the room elected to sit near the fireplace, as they probably would, Joan might be able to steal noiselessly away without being seen or heard. She had not had much time to spare, for ten minutes after she had plastered herself against the wall, Lord and Lady Henry came in. They went to the sofa in front of the fire and chatted of commonplaces until after the coffee and _Orange Marnier_ had been brought. Then Lady Henry took out her jewelled cigarette-case, gave a cigarette to her husband and took one herself. To light hers from his, she perched on Lord Henry’s knee, remaining in that position to play with his hair, her white fingers flashing with rings. She cooed to her husband prettily, saying how nice it was to be with him alone, and how it grieved her to see him weary and worried.
