So they went to the right, through a small thicket of hazel-bushes, over some rocks, and on up the bleak fell-side. The sun had disappeared, and the little golden angels' wings had given place to sombre, grey clouds. It was growing distressingly dark. A spot or two of rain began to fall. The path, degenerated into a mere sheep track, was increasingly difficult to trace. Though neither would admit it, both the girls felt uneasy. They could not recognize any familiar landmarks to show them their whereabouts. Suppose darkness came on, and found them still wandering about on the moor? "Do you think we've come the right way?" asked Diana at last. Wendy looked round in the fading light, hoping against hope to see the corner of Pendlemere gleaming below her in the valley. By now it certainly ought to be visible. Nothing in the shape of a lake, however, appeared in the landscape; only an interminable waste of brown heather under threatening rain-clouds. "No," said Wendy, with a shake in her voice. "As a matter of fact, I believe we're lost." Diana was plucky as a rule, but she was very tired now, and hungry as well. Two somethings that may have been rain-drops splashed down her cheeks; she turned her face away from Wendy as she wiped them off. "What's to be done?" she asked huskily. "Go back, I suppose. Goodness knows where this will lead to!" "We ought to have taken that other turning." "It's too dark to go that way now. We'd better get back to Glenbury, and try for the 'bus." Very soon the girls realized that it was getting too dark even to distinguish the path at all. They stumbled blindly on through the heather, conscious only that they were going downhill, but whether they were really retracing their steps or not, it was impossible to tell. Spot, whose spirits had failed him, followed at their heels. Faster and faster fell the darkness; the girls linked arms to avoid getting separated. They were both thoroughly frightened. Would they be obliged to spend the night upon the moor? If there were only some means of finding the way back to Glenbury! Suddenly, a long distance in front of them, a light flashed out, as though a candle had been placed in a cottage window. Hope revived. If only they could reach some human habitation, they could ask to be directed. They dragged their tired feet along, splashing in the dark through puddles, sinking in soft ground, or stumbling over stones. It seemed an interminable tramp before at last they struck the end of a wall, and, feeling their way with their hands, groped along till they reached a gate. The next moment they were rapping with their knuckles on a door.
