"It's up to us to march," said Harry.

I nodded.

"And step high, Hal; it may be our last one. If we only had our knives! But there are thousands of 'em."

"But if it comes to the worst--"

"Then--I'm with you. Forward!"

We started, and as we did so one of the four who had approached darted from behind and led the way. Not a hand had touched us, and this appeared to me a good sign, without knowing exactly why.

"They seem to have forgotten their manners," Harry observed. "The approved method is to knock us down and carry us. I shall speak to the king about it."

We had just reached the wall of the cavern and entered a pa.s.sage leading from it, when there came a sound, sonorous and ear-destroying, from the farther end. We had heard it once before; it was the same that had ended our desperate fight some days before. Then it had saved our lives; to what did it summon us now?

The pa.s.sage was not a long one. At its end we turned to the right, following our guide. Once I looked back and saw behind us the crowd that had surrounded us in the cave. There was no way but obedience.

We had advanced perhaps a hundred, possibly two hundred yards along the second pa.s.sage when our guide suddenly halted. We stood beside him.

He turned sharply to the left, and, beckoning to us to follow, began to descend a narrow stairway which led directly from the pa.s.sage. It was steep, and the darkness allowed a glimpse only of black walls and the terrace immediately beneath our feet; so we went slowly. I counted the steps; there were ninety-six.

At the bottom we turned again to the right. Just as we turned I heard Harry's voice, quite low:

"There are only a dozen following us, Paul. Now--"

But I shook my head. It would have been mere folly, for, even if we had succeeded in breaking through, we could never have made our way back up the steps. This I told Harry; he admitted reluctantly that I was right.

We now found ourselves in a lane so low and narrow that it was necessary for us to stoop and proceed in single file. Our progress was slow; the guide was continually turning to beckon us on with gestures of impatience.

At length he halted and stood facing us. The guard that followed gathered close in the rear, the guide made a curious upward movement with his arm, and when we stood motionless repeated it several times.

"I suppose he wants us to fly," said Harry with so genuine a tone of sarcasm that I gave an involuntary smile.

The guide's meaning was soon evident. It took some seconds for my eye to penetrate the darkness, and then I saw a spiral stair ascending perpendicularly, apparently carved from the solid rock. Harry must have perceived it at the same moment, for he turned to me with a short laugh:

"Going up? Not for me, thank you. The beggar means for us to go alone."

For a moment I hesitated, glancing round uncertainly at the dusky forms that were ever pressing closer upon us. We were a.s.suredly between the devil and the deep sea.

Then I said, shrugging my shoulders: "It's no good pulling, Harry.

Come on; take a chance. You said it--going up!"

I placed my foot on the first step of the spiral stair.

Harry followed without comment. Up we went together, but slowly. The stair was fearfully steep and narrow, and more than once I barely escaped a fall.

Suddenly I became aware that light was descending on us from above.

With every step upward it became brighter, until finally it was as though a noonday sun shone in upon us.

There came an exclamation from Harry, and we ascended faster. I remember that I counted a hundred and sixty steps--and then, as a glimmering of the truth shot through my brain into certainty, I counted no more.

Harry was crowding me from below, and we took the last few steps almost at a run. Then the end, and we stumbled out into a blaze of light and surveyed the surrounding scene with stupefaction and wonder.

It was not new to us; we had seen it before, but from a different angle.

We were on the top of the column in the center of the lake; on the spot where Desiree had whirled in the dance of the sun.

Chapter X.

THE VERDICT.

For many seconds we stood bewildered, too dazed to speak or move. The light dazzled our eyes; we seemed surrounded by an impenetrable wall of flame. There was no sensation of heat, owing, no doubt, to the immense height of the cavern and our comparatively distant removal from the flames, which mounted upward in narrow tongues.

Then the details began to strike me.

I have said the scene was the same as that we had previously beheld.

Round the walls of the immense circular cavern squatted innumerable rows of the Incas on terraced seats.

Below, at a dizzy distance, was the smooth surface of the lake, black and gloomy save where the reflections from the blazing urns pierced its depths. And directly facing us, set in the wall of the cavern, was the alcove containing the throne of gold.

And on the throne was seated--not the diminutive, misshapen king, but Desiree Le Mire!

She sat motionless, gazing directly at us. Her long gold hair streamed over her shoulders in magnificent waves; a stiffly flowing garment of some unknown texture covered her limbs and the lower part of her body; her shoulders and b.r.e.a.s.t.s and arms were bare, and shone with a dazzling whiteness.

Beside her was a smaller seat, also of gold, and on this crouched the form of an Inca--the king. About them, at a respectful distance, were ranged attendants and guards--a hundred or more, for the alcove was of an impressive size. The light from the four urns shone in upon it with such brightness that I could clearly distinguish the whites of Desiree's eyes.

All this I saw in a single flash, and I turned to Harry:

"Not a word, on your life! This is Desiree's game; trust her to play it."

"But what the deuce is she doing there?"

I shrugged my shoulders.

"She seems to have found another king. You know her fondness for royalty."

"Paul, for Heaven's sake--"

"All right, Hal. But we're safe enough, I think. Most probably our introduction to court. This is what they call 'the dizzy heights of prominence.' Now keep your eyes open--something is going to happen."

There was a movement in the alcove. Four of the attendants came forward, carrying a curious framework apparently composed of reeds and leather, light and flexible, from the top bar of which hung suspended several rope-like ribbons, of various lengths and colors and tied in curious knots. They placed it on the ground before the double throne, at the feet of Desiree.

All doubt was then removed from my mind concerning the ident.i.ty of our captors and their king. For these bundles of knotted cords of different sizes and colors I recognized at once.

They were the famous Inca quipos--the material for their remarkable mnemonic system of communication and historical record. At last we were to receive a message from the Child of the Sun.
