The fellow lifted his hat, and stepped back into the passage, his manner insolent. She remained motionless, contempt in her eyes, but in truth hopeless and crushed. Silva closed the door silently, although her ears caught the click of the bolt when it was shot home.

No sound of their retreating footsteps reached her through the thick wall. The stillness of her prison seemed to strike her like a blow. For a moment she stood staring at the bare wall, her lips parted, her limbs trembling from the reaction of excitement; then she stepped forward, and felt along the smooth surface of rock.

The door fitted so closely she could not even determine its exact outlines. Baffled, her glance wandered about the cell, seeking vainly for any sign of weakness, and then, giving way utterly to her despair, the girl flung herself on the bench, covering her eyes to shut out those hideous surroundings. What should she do? What could she do? What possibility of hope lay in her own endeavours? From what source could she expect any outside help?

After those first moments of complete despair, there came greater calmness, in which her mind began to grapple with the situation. Life had never been an easy problem, and discouragement was no part of her creed. She sat up once more, her lips pressed tightly together, her eyes dry of tears.

In spite of Cateras's cowardly threats these outlaws would never dare to take her life. There was no occasion for them to resort to so desperate a deed. Besides this Mexican was only an under officer of the band, and would never venture to oppose the will of his chief. Her fate rested not on his word, but upon the decision of Pasqual Mendez, and, if that bandit was associated with Bill Lacy, as undoubtedly he was, then as the prisoner of the American, she was certainly safe until the latter expressed his own wish regarding her.

And why should Lacy desire to take her life? Most assuredly he did not, or the act would have been already accomplished. The very fact of her having been transported such a distance was sufficient evidence of his purpose. The conspirators merely suspected her mission in Haskell; they were afraid she knew more of their plans than she really did. The telegram, stolen by Miss La Rue, had convinced the leaders that she might prove dangerous if left at large, and they had determined to hold her helpless until their scheme had been worked out and they were safely beyond pursuit. That was undoubtedly the one object of her capture. Lacy had no knowledge that Mendez's band was at the rendezvous; he supposed them to be on a cattle raid to the south, with only a man or two of his own left as guard over Cavendish.

Cavendish! Her mind grasped clearly now the fact that the man was not dead. It had not been his body found in the Waldron Apartments, but that of some other man substituted for purposes of crime. Cavendish himself had been lured westward, waylaid in some manner and made prisoner, as she and Westcott had suspected.

Through the co-operation of Lacy he had been brought to this desert den, where he could be held indefinitely, with no chance of discovery—killed if necessary. She had heard of such places as this, read of them, yet never before had she realised the possibility of their real existence. It all seemed more like a delirium of fever than an actual fact. She rubbed her eyes, gazing about on the rock walls, scarcely sure she was actually awake. Why, one might ride across that desert, and pass by within a hundred yards of its rim, and never even be aware of the existence of this sunken valley. Perhaps not a dozen men outside this gang of outlaws had ever gazed down into its green depths, and possibly no others knew of that narrow, winding trail leading down to its level. Yet these men must have made use of it for years, as a place to hide stolen cattle, and into which to retreat whenever pursuit became dangerous.

Those huts without were not newly built, and this underground cavern had been extended and changed by no small labour. What deeds of violence must have happened here; what scenes of unbridled debauchery this desert rendezvous must have witnessed. She shuddered at the thought, comprehending that these cells had never been chiselled without a purpose, and that she was utterly helpless in the hands of a band of thieves and cutthroats, to whom murder meant little enough, if it only served their ends. Mendez, no doubt, was brute and monster, yet it was Juan Cateras whom she really feared—he was cruel, slimy, seeking to hide his hatefulness behind that hideous smile; and he had already chosen her for his victim. Who would save her—Mendez? Lacy? God, she did not know: and somehow neither of these was the name which arose to her lips, almost in the form of prayer; the name she whispered with a faint throb of hope in its utterance—Jim Westcott.

The big miner was all she had to rely upon; he had been in her mind all through the long ride; he arose before her again now, and she welcomed the memory with a conscious throb of expectation. Those people back there could not conceal for long her absence from him; if he lived he would surely seek her again.
