m, while we halted till he made an investigation. It was impossible
to see the face of the half-witted guide to gain any information from
his gestures.

Holman stooped and whispered his finding to us. "We're in a covered
passageway," he murmured. "I can just touch the roof by standing on
tiptoe. As we're in the place we might as well walk instead of crawling;
we'll get to the end quicker."

Maru dragged One Eye to his feet, and we pushed on. The air of the place
was much sweeter than the atmosphere of the Cavern of Skulls. The
floor, instead of being covered with thick dust as we had found it in
the former place, was one of clean, smooth rock, and the walls were
perfectly dry.

I had gripped One Eye's left arm while Holman was making the examination
of the passage, and we had not proceeded more than twenty yards when he
intimated that he wished to turn to the right. We allowed him to do so,
and for fully twenty minutes he followed a zigzag course that left us
completely nonplussed as to the way we had come. We could hardly count
the number of the turnings. First to the right, then to the left, then
back again toward the mouth of the place, he trotted forward with
nothing to guide him, yet when we checked him at certain corners to find
out if there was an angle in the path, we found that he was right in
every instance.

"He's counting the number of paces he takes between the turnings,"
muttered Holman. "No man, unless he had the eyes of a cat, could find
his way along this passage. Keep a grip on him or we'll never see
daylight again."

We guessed that we had walked for over half a mile when the guide
stopped abruptly. In the dark we endeavoured to find out what had pulled
him up short, but we tried in vain. A prick from Kaipi's knife blade
would not make him budge an inch, and we clustered together and racked
our brains to find the solution.

"P'raps we're up against something," whispered Holman, "Feel if there's
anything in front, Verslun."

I walked forward a pace and groped in the blackness. My fingers touched
solid rock. It hemmed us in on all sides. One Eye had walked us to the
end of the passage, and we had come up against a blind wall.

I whispered the news to Holman, and he swore softly. Maru's fingers
tightened on the collar of the prisoner till his breath came in short
gasps. Kaipi moved around to the side of the prisoner, but I pushed him
roughly back. The Fijian's desire to use his knife on all occ
