de sac! To our ears was borne a louder shouting.
The first of the pursuing shells had swept over the lip of the great bowl, poised for a moment as we had and then began a cautious descent. Within it, scanning the slopes, I saw Lugur.
“A little closer and I’ll get him!” whispered Larry viciously. He raised his pistol.
His hand was caught in a mighty grip; Rador, eyes blazing, stood beside him.
“No!” rasped the green dwarf. He heaved a shoulder against one of the boulders that formed the pocket. It rocked aside, revealing a slit.
“In!” ordered he, straining against the weight of the stone. O’Keefe slipped through. Olaf at his back, I following. With a lightning leap the dwarf was beside me, the huge rock missing him by a hair breadth as it swung into place!
We were in Cimmerian darkness. I felt for my pocket-flash and recalled with distress that I had left it behind with my medicine kit when we fled from the gardens. But Rador seemed to need no light.
“Grip hands!” he ordered. We crept, single file, holding to each other like children, through the black. At last the green dwarf paused.
“Await me here,” he whispered. “Do not move. And for your lives — be silent!”
And he was gone.
CHAPTER XXIII
DRAGON WORM AND MOSS DEATH
For a small eternity — to me at least — we waited. Then as silent as ever the green dwarf returned. “It is well,” he said, some of the strain gone from his voice. “Grip hands again, and follow.”
“Wait a bit, Rador,” this was Larry. “Does Lugur know this side entrance? If he does, why not let Olaf and me go back to the opening and pick them off as they come in? We could hold the lot — and in the meantime you and Goodwin could go after Lakla for help.”
“Lugur knows the secret of the Portal — if he dare use it,” answered the captain, with a curious indirection. “And now that they have challenged the Silent Ones I think he WILL dare. Also, he will find our tracks — and it may be that he knows this hidden way.”
“Well, for God’s sake!” O’Keefe’s appalled bewilderment was almost ludicrous. “If HE knows all that, and YOU knew all that, why didn’t you let me click him when I had the chance?”
“Larree,” the green dwarf was oddly humble. “It seemed good to me, too — at first. And then I heard a command, heard it clearly, to stop you — that Lugur die not now, lest a greater vengeance fail!”
“Command? From whom?” The Irishman’s voice distilled out of the blackness the very essence of bewilderment.
“I thought,” Rador was whispering —“I thought it came from the Silent Ones!”
“Superstition!” groaned O’Keefe in utter exasperation. “Always superstition! What can you do against it!
“Never mind, Rador.” His sense of humour came to his aid. “It’s too late now, anyway. Where do we go from here, old dear?” he laughed.
“We tread the path of one I am not fain to meet,” answered Rador. “But if meet we must, point the death tubes at the pale shield he bears upon his throat and send the flame into the flower of cold fire that is its centre — nor look into his eyes!”
Again Larry gasped, and I with him.
“It’s getting too deep for me, Doc,” he muttered dejectedly. “Can you make head or tail of it?”
“No,” I answered, shortly enough, “but Rador fears something and that’s his description of it.”
“Sure,” he replied, “only it’s a code I don’t understand.” I could feel his grin. “All right for the flower of cold fire, Rador, and I won’t look into his eyes,” he went on cheerfully. “But hadn’t we better be moving?”
“Come!” said the soldier; again hand in hand we went blindly on.
O’Keefe was muttering to himself.
“Flower of cold fire! Don’t look into his eyes! Some joint! Damned superstition.” Then he chuckled and carolled, softly:
“Oh, mama, pin a cold rose on me;
Two young frog-men are in love with me;
Shut my eyes so I can’t see.”
“Sh!” Rador was warning; he began whispering. “For half a va we go along a way of death. From its peril we pass into another against whose dangers I can guard you. But in part this is in view of the roadway and it may be that Lugur will see us. If so, we must fight as best we can. If we pass these two roads safely, then is the way to the Crimson Sea clear, nor need we fear Lugur nor any. And there is another thing — that Lugur does not know — when he opens the Portal the Silent Ones will hear and Lakla and the Akka will be swift to greet its opener.”
“Rador,” I asked, “how know YOU all this?”
“The handmaiden is my own sister’s child,” he answered quietly.
O’Keefe drew a long breath.
“Uncle,” he remarked casually in English, “meet the man who’s going to be your nephew!”
And thereafter he never addressed the green dwarf except by the avuncular title, which Rador, humorously enough, apparently conceived to be one of respectful endearment.
For me a light broke. Plain now was the reason for his foreknowledge of Lakla’s appearance at the feast where Larry had so narrowly escaped Yolara’s spells; plain the determining factor that had cast his lot with ours, and my confidence, despite his discourse of mysterious perils, experienced a remarkable quickening.
Speculation as to the marked differences in pigmentation and appearance of niece and uncle was dissipated by my consciousness that we were now moving in a dim half-light. We were in a fairly wide tunnel. Not far ahead the gleam filtered, pale yellow like sunlight sifting through the leaves of autumn poplars. And as we drove closer to its source I saw that it did indeed pass through a leafy screen hanging over the passage end. This Rador drew aside cautiously, beckoned us and we stepped through.
It appeared to be a tunnel cut through soft green mould. Its base was a flat strip of pathway a yard wide from which the walls curved out in perfect cylindrical form, smoothed and evened with utmost nicety. Thirty feet wide they were at their widest, then drew toward each other with no break in their symmetry; they did not close. Above was, roughly, a ten-foot rift, ragged edged, through which poured light like that in the heart of pale amber, a buttercup light shot through with curiously evanescent bronze shadows.
“Quick!” commanded Rador, uneasily, and set off at a sharp pace.
Now, my eyes accustomed to the strange light, I saw that the tunnel’s walls were of moss. In them I
