Then suddenly Ora turned cold with the chill of the mine itself, a mere physical attribute that her warm blood had never deigned to notice before. A form was slowly coming into view below the high roof of the cavern, and although it was little more than a blot on the general blackness, Ora’s keen eyes, accustomed to the faint relief given by the candle near the shaft, noted as it descended further that it covered more of the ladder than it should. Miners are almost invariably thin and they wear overalls. This person wore a heavy cape like her own. But it was not alone the garment, which any miner would scorn, that betrayed the sex of the invader; it may have been the physical awkwardness, the shallow breathing, or some subtle psychical emanation--or all--that warned Ora of the approach not only of a woman but of a malignant force. And this woman was following her. There was no doubt in her mind of that. She suffered a moment or two of furious unreasoning terror as she crouched against the wall and watched that shadow against a shadow slowly descend the final rungs of the ladder. Her first impulse had been to flee down the drift, but there was danger of falling into one of the gouge holes and disabling herself. She dared not relight her candle. Shaking, terrified as she never had been in her life--for she was normally brave, and it was not a normal woman she feared but that aura of hate and lust for vengeance--undecided, putting up a frantic prayer that Gregory would come to her rescue, she pulled the hood over her face and almost sank to her knees. The woman, breathing heavily, reached the last rung and touched the ground as warily as a cat. For a moment she stood drawing in deep breaths like sighs, but which escaped, to tormented ears, like a hiss. Ora, her eyelids almost meeting over the intense concentration of her gaze, saw the woman fling back the mantle that covered her, throw out her arms as if to relax the muscles after the strain of the descent. Then she turned suddenly, snatched the candlestick from the wall and held it above her head. For the moment Ora thought her heart had stopped. The woman was Ida. Her heavy lowered brows were like a heavy band across the white ghastliness of her face. Her eyes glittered horribly. Her lips were a mere tight line. Her black hair, loosened, fell over her face. Ora’s hypnotised gaze tore itself from those slowly moving eyes and lowered itself instinctively to Ida’s right hand. It held the stiletto she had given her in Genoa. The slanting rays of the candle fell on the jewels of the hilt. Then she knew that Ida had followed her down into the mine to kill her.
