"I may do an even stranger thing than that, once the thing is in my possession!"
"I am not concerned with your mysteries," I shrugged. "All I need to know about you is that you and I have an agreement which we both intend to keep. Now, tell me all you can, that I may surely find that place where the Sapphire Image is hidden."
So for the rest of the night we three sat listening while that gentle-seeming old man told us in detail all he knew about our course—while at the same time he warned us frankly that we were going direct into the worst antechamber of Hell when we reached the entrance to the cavern. And, as we later found out for ourselves, he understated. . . .
"Lord Karan," Koto said, pointing—"unless Agnor Halit lied, yon place is the entrance to the cavern we seek."
We dismounted after one glance, for the marks were unmistakable. Five huge boulders indicated the angles of a pentagon; in the center, a pool, evidently filled with water from the Sea of the Dead through some underground channel. To substantiate this supposition, the surface of the pool heaved with the heaving of the surges along the beach some few hundred yards distant.
Even as we watched, the surface became violently agitated; a vortex formed, became a miniature whirlpool, making queer sucking noises, strange gurglings and whistling moans. This lasted for upward of an hour. After that, the surface became level and still.
Then abruptly came a change. In the very center a huge bubble rose and burst, polluting the atmosphere with a most unholy stench. More bubbles rose and the stench grew worse. Bubbles came continually, and the pool boiled like a cauldron, filling the air with horrible odor. Then again the surface stilled.
Now my courage well-nigh forsook me, and without shame I admit it. For I knew I'd have to dive into that loathly pool while the vortex pulled downward; and come up—if ever I did come up—while the bubbles arose! And it was in nowise a pleasing prospect. After we'd been studying the pool for some time, Zarf evidently came to the same conclusion I had reached, for he said bluntly:
"My King, that old devil, Agnor Halit laid a trap for you! It is well known that King Karan does not lightly break his word. But if I, Zarf, have aught to say about this matter, here is once Karan of Octolan breaks a pledge, nor gives it a second thought. To plunge into that pool is the act of a madman. If that damned sorcerer wants that image so badly, let him come and dive for it himself. He will only go to Hell a little sooner, through a most befitting gateway, and this region of space will be that much improved because of his absence!
"But my memory, Zarf?"
"Once you've gone into that filthy hole, you'll have no need for it, as
