Minutes passed, and she did not reappear. Juliet waited, her nerves stretched in expectation, but nothing happened. Overhead little birds, tomtits and creepers, played about the bark of the fir-trees; a robin came and looked at her consideringly, with a bright sensible eye; from two hundred feet below, the murmur of the burn rose constant and insistent; but no other sound broke the stillness, nor was there any sign of human life upon the top of the cliff. At last the girl could stand it no longer. Her patience was exhausted. Curiosity urged her like a goad; and, if she had not much expectation of making any important discovery, she was at least determined to solve the mystery that now perplexed her. Without more ado she got to her feet, and ran to the holly hedge. There, throwing herself down once more, she parted the leaves with a cautious hand, and followed the path taken by the Russian. The hedge was old and very thick, more than three yards in width at this end of it. In the middle, the trunks of the trees that formed it rose in a close-growing, impassable barrier; but just opposite the place where Julia had vanished Juliet found that there was a gap, caused, perhaps, by the death in earlier days of one of the trees, or, as she afterwards thought more likely, by the intentional omission or destruction of one of the young plants. It was a narrow opening, but she managed to wriggle through it. On the other side, progress was bounded by the wall, whose massive granite blocks presented a smooth unbroken surface. Where, then, had Julia gone? The branches did not grow low on this, as on the outer side of the hedge, and there was room to stand, though not to stand upright. Stooping uncomfortably, the girl looked about her, and saw in the soft brown earth the plain print of many footsteps, both going and coming, between the place where she crouched and the end of the wall. She looked behind her, and there were no marks. Clearly, Julia had gone to the end; but what then? The corner of the wall was at the very edge of the precipice; from what she remembered to have seen from below, the rock was too sheer to offer any foothold; besides why, having just climbed to the summit should anyone immediately descend again, and by such an extraordinary route? While these thoughts followed one another in her mind, Juliet had advanced along the track of the footsteps, and clinging tightly to the trunk of the last holly bush she leant forward and looked down. As she thought, the descent was impossible: the rock fell away at her feet, sheer and smooth; there was no path there that a cat could take. It made her giddy to look, and she drew back hurriedly. Where, then, could Julia have gone? Not to the left, that was certain, for then she would have emerged again into view. To the right? That seemed impossible. Still, Juliet leant forward again, and peered round the corner of the wall.
