And in truth it was a glorious day for a walk. The thermometer had fallen abruptly after a heavy mist, and the great stretch of fields was perfectly white with the deepest hoar-frost Mona had ever seen. From every stone in the dyke, every blade of grass by the wayside, every hardy scrap of moss and lichen, the most exquisite ice-needles stood out in wonderful coruscations, sparkling and blazing in the slanting rays of the afternoon sun; a huge spider's web in the window of an old barn looked like some marvellous piece of fairy lacework; the cart-ruts in the more deserted roads were spanned by tiny rafters of ice; and above all, the moon, modest and retiring as yet, looked down from an infinitely distant expanse of pale, cloudless sky. Very slowly the sun sank below the horizon, and the moon asserted herself more and more; till, when Mona reached the pine-wood, the mystic, unearthly beauty of the scene brought the actual tears into her eyes. The silence was broken only by sounds that served to gauge its depth; the recesses of the wood were as gloomy and mysterious as ever; but the moonlight streamed down on graceful tops and spreading branches, not burdened with massive whiteness, but transformed into crystal. A pine-wood in snow is a sight to be seen, but the work of the snow is only a daub, after all, when compared with the artist touch of a frost like this. Mona scarcely knew how long she stood there, unwilling even to lean against the gate and so destroy its perfect bloom; but she was disturbed at last by the sound of wheels on the carriage-drive. Had the Colonel come back? Was Jenny ill? And then with a quick flash of conviction she knew whom she was going to see. It was Dudley, leading his horse by the bridle, and looking worn and anxious. He brightened up and quickened his step when he saw a woman's figure at the gate; then recognised who it was, and stopped short, with something like a groan. Poor Dudley! A moment before he would have given almost anything he possessed for the presence of a female human creature, and now that his prayer was granted, how he wished that it had been any other woman in the world than just this one whom the Fates had sent! He had no choice, however, and he plunged into the matter at once, with white lips, but with a quick, resolute voice. "I am in a sore dilemma, Miss Maclean," he said. "I was sent for suddenly up country to a case of arsenical poisoning; and, as I went past, they stopped me at those cottar-houses to tell me that there was a poor soul in extremity here. It's your little Maggie, by the way. Poor child! She may well ask herself whether life is worth living now! Of course I had to go on to my man, but I left him before I really ought to have done so, and now I must hurry back. The baby is just born." "Is Jenny here?" Mona found it difficult to speak at all in the deafening rush of sorrow and bitterness that came over her.
