ned. "Is there something wrong?"
He reached back and drew her closer, without answering, until her eyes
also were able to look around the sharp edge of rock. Far away, it
seemed a long distance up that narrow tunnel, a lantern glowed dully,
the light so dim and flickering as to scarcely reveal even its
immediate surroundings; yet from that distance, her eyes accustomed to
the dense gloom, she could distinguish enough to quicken her breathing
and cause her to clutch the sleeve of her companion.
The lantern occupied a niche in the side wall at the bottom of a flight
of rude steps. Not more than a half-dozen of these were revealed, but
at their foot, where the passage had been widened somewhat, extended a
stone bench, on which lounged two men. One was lying back, his head
pillowed on a rolled coat, yet was evidently awake; for the other,
seated below him, with knees drawn up for comfort, kept up conversation
in a low voice, the words being inaudible at that distance. Even in
that dim light the two were clearly Mexican.
"What shall we do?" she asked, her lips at Cavendish's ear. "We cannot
pass them--they are on guard."
"I was wondering how close I could creep in before they saw me," he

chances of surprise. What do you think best?"
"Even if you succeeded in overawing these two, we would have no way of
securing them. An alarm would be given before we could get beyond
reach. Our only hope of escape lies in getting out of here unseen."
"Yes, and before Cateras is discovered."
"He gave no orders to the guard to return?"
"No; but he will be missed after a while and sought for. We cannot
count on any long delay, and when it is found that he has been knocked
out, and we have disappeared, every inch of this cave will be searched.
There is no place to hide, and only the two ways by which to get out."
"Then, let's go back and try the other," she urged. "That opens
directly into the valley and is probably not guarded. What is
happening now?"
A grey gleam of light struck the steps from above, recognised instantly
as a reflection of day, as though some cover had been uplifted
connecting this underground labyrinth with the clear sky. A dim shadow
