"It's so much worse now it's dark," groaned Aldred.
She was in a very dejected frame of mind, and would have burst out sobbing like a baby if she had not been too proud. Her friends were also in low spirits, and did not keep up their usual flow of jokes and chatter. All four snuggled as close together as they could, to keep one another warm, and sat silent, listening to the waves and the rain, till kind Mother Nature sent merciful sleep, and for a while at least they were able to forget their troubles.
Aldred had a long and confusing dream. She thought that she saw Mabel in danger of drowning, and that she plunged boldly into the sea, swam easily to her aid, and brought her back to shore amid the cheers of the school; and that Mabel was saying: "I knew you would come to the rescue. It's not the first time you have done a heroic deed!"
She woke with a start. The words seemed so clear, she could almost believe Mabel had really spoken them. Certainly she had done nothing particularly heroic that day; indeed, her conscience told her that she was mainly responsible for that unpleasant adventure. It was she who had begged the others to leave the post office, and urged them to go down the promenade and along the pier. But for her it would not have occurred to them to break bounds; they would have waited until Blanche and Freda returned, walked straight back to school, and considered that they had had an enjoyable afternoon, without transgressing rules. None of them, however, had accused her of this. They appeared perfectly ready to take the full blame—indeed, they had hinted that, as a new girl, she would probably escape the consequences of the escapade more easily than they.
"After all, it's mostly their fault, for they'd no need to come, even if I asked them," she decided hastily. "I'm not bound to explain everything and get into extra trouble. No one is likely to ask who suggested it."
She tried to stretch her cramped limbs, and felt so stiff that it was pain to move. But it was worse to remain in the same position; so, making an effort, she dragged herself up, and crept out from under the rock. The rain had stopped, and a full moon was shining outside, so clearly that she was able to consult her watch and ascertain that it was a little after ten o'clock. She roused the others immediately.
"Look—look!" she cried, shaking them eagerly. "It's bright moonlight! The tide will have gone down. We must try to get on to the sands at once."
Yawning and stretching, the girls emerged from the cave. It was sufficiently light for them to see their way over the rocks, so they set off without further delay in the direction of the shore. They were now able to cross easily at the place where the channel had stretched a few hours earlier, and found themselves, after a considerable amount of scrambling, on the beach at the farther side of the promontory.
It was the queerest walk home that they had ever experienced. Sands are generally associated with blue sky and bright sunshine, and those seemed very eerie and weird and strange in the moonlight, with the deep, dark shadows under the cliffs, and the sea gleaming silver in the distance. With one consent they took each others' arms. Aldred certainly did not feel sufficiently courageous to walk alone; moreover, she was tired, and could contrive to lean upon both Phœbe and Myfanwy, who were kind enough to pull her along without remonstrance.
The sands on this part of the shore were not very firm, and the girls' feet sank with every step, while they stumbled now and then over stones or clumps of seaweed. It took a long time to cover the three miles to Birkwood; the distance seemed twice as far as it would have done by day, and they were thankful when at last they found the path which they knew led up the cliffs to the Grange.
