When Isabel came slowly forth at length from the hotel door whither Biddy had conducted her, Scott was sitting alone on a bench in the sunshine.
He rose at once to join her. "Why, how quick you have been! Or else the time flies here. Eustace is still skating. I had no idea he was so accomplished. See, there he is!"
But Isabel set her haggard face towards the mountain-road that wound up beyond the hotel. "I am going to look for Basil," she said.
"It is waste of time," said Scott quietly.
But he did not attempt to withstand her. They turned side by side up the hard, snowy track.
For some time they walked in silence. At a short distance from the hotel, the road ascended steeply through a pine-wood, dark and mysterious as an enchanted forest, through which there rose the sound of a rushing stream.
Scott paused to listen, but instantly his sister laid an imperious hand upon him.
"I can't wait," she said. "I am sure he is just round the corner. I heard him whistle."
He moved on in response to her insistence. "I heard that whistle too," he said. "But it was a mountain-boy."
He was right. At a curve in the road, they met a young Swiss lad who went by them with a smile and salute, and fell to whistling again when he had passed.
Isabel pressed on in silence. She had started in feverish haste, but her speed was gradually slackening. She looked neither to right nor left; her eyes perpetually strained forward as though they sought for something just beyond their range of vision. For a while Scott limped beside her without speaking, but at last as they sighted the end of the pine-wood he gently broke the silence.
"Isabel dear, I think we must turn back very soon."
"Oh, why?" she said. "Why? You always say that when--" There came a break in her voice, and she ceased to speak.
Her pace quickened so that he had some difficulty in keeping up with her, but he made no protest. With the utmost patience he also pressed on.
But it was not long before her strength began to fail. She stumbled once or twice, and he put a supporting hand under her elbow. As they neared the edge of the pines it became evident that the road dwindled to a mere mountain-path winding steeply upwards through the snow. The sun shone dazzlingly upon the great waste of whiteness.
