There must be small stones somewhere about, and she began to look out for them. She reached the bottom of the circular depression, and pushing aside a bush to make further progress, feeling all the time with her feet for a suitable prop, suddenly she slipped. She was dropping down a sloping shaft into the depths of the earth!

CHAPTER XXXVIII
THE CAVERN OF BONES

Down, down, down she fell, one hand clawing wildly at the soft earth, the other clenching unconsciously at the tiny pistol. She was rolling down a steep slope. Once her feet came violently and painfully into contact with an out-jutting rock, and the shock and the pain of it turned her sick and faint. Whither she was going she dared not think. It seemed an eternity before, at last, she struck a level floor and, rolling over and over, was brought up against a rocky wall with a jolt that shook the breath from her body.

Eternity it seemed, yet it could not have been more than a few seconds. For five minutes she lay, recovering, on the rock floor. She got up with a grimace of pain, felt her hurt ankle, and worked her foot to discover if anything was broken. Looking up, she saw a pale star above, and, guessing that it was the opening through which she had fallen, attempted to climb back; but with every step she took the soft earth gave under her feet and she slipped back again.

She had lost a shoe: that was the first tangible truth that asserted itself. She groped round in the darkness and found it after a while, half embedded in the earth. She shook it empty, dusted her stockinged foot, and put it on. Then she sat down to wonder what she should do next. She guessed that, with the coming of day, she would be able to examine her surroundings, and she must wait, with what philosophy she could summon, for the morning to break.

It was then that she became conscious that she was still gripping the earth-caked Browning, and, with a half-smile, she cleaned it as best she could, pressed down the safety-catch and, putting the weapon inside her blouse, thrust its blunt nose into the waistband of her skirt.

The mystery of Bhag’s reappearance was now a mystery no longer. He had been hiding in the cave, though it was her imagination that supplied the queer animal scent which was peculiarly his.

How far did the cave extend? She peered left and right, but could see nothing; then, groping cautiously, feeling every inch of her way, her hand struck a stone pillar, and she withdrew it quickly, for it was wet and clammy.

And then she made a discovery of the greatest importance to her. She was feeling along the wall when her hand went into a niche, and by the surface of its shelf she knew it was man-fashioned. She put her hand farther along, and her heart leapt as she touched something which had a familiar and homely feel. It was a lantern. Her other hand went up, and presently she opened its glass door and felt a length of candle, and, at the bottom of the lantern, a small box of matches.

It was no miracle, as she was to learn; but for the moment it seemed that that possibility of light had come in answer to her unspoken prayers. Striking a match with a hand that shook so that the light went out immediately, she at last succeeded in kindling the wick. The candle was new, and at first its light was feeble; but presently the wax began to burn, and, closing the lantern door, her surroundings came into view.
