At a spot immediately below the light from the window, he dived. Down he went, the water becoming colder almost with every stroke. His ears began to ache, then to hurt intensely. He blew some bubbles of air out to relieve the pressure, but he was not helped much by this. Just as it seemed that he could go no deeper without his ears bursting, his hand plunged into soft mud. Restraining the desire to turn at once and swim upwards for the blessed relief from pressure and the absolutely needed air, he groped around on the floor of the moat. He found nothing but mud and, once, a bone. He drove himself until he knew he had to have air.
Twice he rose to the surface and then dived again. By now, he knew that even if the horn were lying on the bottom, he might not ever find it. Blind in the murky waters, he could pass within an inch of the horn and never know it. Moreover, it was possible that Smeel had thrown the horn far away from him when he had fallen. Or a water-dragon could have carried it off with Smeel’s corpse, even swallowed the horn.
The third time, he swam a few strokes to the right from his previous dives before plunging under. He dived down at what he hoped was a ninety-degree angle from the bottom. In the blackness, he had no way of determining direction. His hand plowed into the mud; he settled close to it to feel around, and his fingers closed upon cold metal. A quick slide of them along the object passed over seven little buttons.
When he reached the surface, he trod water and gasped for wind. Now to make the trip back, which he hoped he could do. The water-dragons could still show up.
Then he forgot the dragons, for he could see nothing. The torchlight from the drawbridge, the feeble moonglow through the clouds, the light from the window overhead, all these were gone.
Wolff forced himself to keep on treading water while he thought his situation through. For one thing, there was no breeze. The air was stale. Thus, he could only be in one place, and it was his fortune that such a place happened to be just where he had dived. Also, it was his luck that he had come up from the bottom at an oblique angle.
Still, he could not see which way was shoreward and which way was castleward. To find out took only a few strokes. His hand contacted stone—stone bricks. He groped along it until it began to curve inward. Following the curve, he finally came to that which he had hoped for. It was a flight of stone steps that rose out of the water and led upward.
He climbed up it, slowly, his hand out for a sudden obstacle. His feet slid over each step, ready to pause if an opening appeared or a step seemed loose. After twenty steps upward, he came to their end. He was in a corridor cut out of stone.
Von Elgers, or whoever had built the castle, had constructed a means for secret entrance and exit. An opening below water level in the walls led to a chamber, a little port, and from thence into the castle. Now, Wolff had the horn and a way to get unnoticed into the castle. But he did not know what to do. Should he return the horn to the gworl first? Afterward, he and the two others could return this way and search for Chryseis.
He doubted that Ghaghrill would keep his word. However, even if the gworl were to release their captives, if they swam to this place, Kickaha’s wound would draw the saurians and all three would be lost. Chryseis would have no chance of getting free. Kickaha could not be left behind while the other two went back to the castle. He would be exposed as soon as dawn came. He could hide in the woods, but the chances were that another hunting party would be searching that area then. Especially after it was discovered that the three stranger knights were gone.
He decided to go on down the hall. This was too good a chance to pass up. He would do his best before daylight. If he failed, then he would go back with the horn.
The horn! No use taking that with him. Should he be captured without it, his knowledge of its location might help him.
He returned to where the steps came to an end below the water. He dived down to a depth of about ten feet and left the horn on the mud.
Back in the corridor, he shuffled until he came to more steps at its end. The flight led upward on a tight spiraling course. A count of steps led him to think that he had ascended at least five stories. At every estimated story he felt around the narrow walls for doors or releases to open doors. He found none.
At what could have been the seventh story, he saw a tiny beam of light from a hole in the wall. Bending down, he peered through it. By the far end of the room, seated at a table, a bottle of wine before him, was Baron von Elgers. The man seated across the table from the baron was Abiru.
The baron’s face was flushed by more than drink. He snarled at Abiru, “That’s all I intend to say, Khamshem! You will get the horn back from the gworl, or I’ll have your head! Only first you’ll be taken to the dungeon! I have some curious iron devices there that you will be interested in!”
Abiru rose. His face was as pale beneath its dark pigment as the baron’s was crimson.
“Believe me, sire, if the horn has been taken by the gworl, it will be recovered. They can’t have gone far with it—if they have it—and they can easily be tracked down. They can’t pass themselves off as human beings, you know. Besides, they’re stupid.”
The baron roared, stood up, and crashed his fist against the top of the table.
“Stupid! They were clever enough to break out of my dungeon, and I would would have sworn that no one could do that! And they found my room and took the horn! You call that stupid!”
“At least,” Abiru said, “they didn’t steal the girl, too. I’ll get something out of this: She should fetch a fabulous price.”
“She’ll fetch nothing for you! She is mine!”
Abiru glared and said, “She is my property. I obtained her at great peril and brought her all this way at much expense. I am entitled to her. What are you, a man of honor or a thief?”
Von Elgers struck him and knocked him down. Abiru, rubbing his cheek, got to his feet at once. Looking steadily at the baron, his voice tight, he said, “And what about my jewels?”
“They are in my castle!” the baron shouted. “And what is in my castle is the von Elgers’!”
He strode away out of Wolff’s sight but apparently opened a door. He bellowed for the guard, and when they had come they took Abiru away between them.
“You are fortunate I do not kill you!” the baron raged. “I am allowing you to keep your life, you miserable dog! You should get down on your knees and thank me for that! Now get out of the castle at once. If I hear that you are not making all possible speed to another state, I will have you hung on the nearest tree!”
Abiru did not reply. The door closed. The baron paced back and forth for awhile, then abruptly came toward the wall behind which Wolff was crouched. Wolff left the peephole and retreated far down the steps. He hoped he had chosen the right direction in which to go. If the baron came down the staircase, he could force Wolff into the water and perhaps back out into the moat. But he did not think the baron intended to come that way.
For a second the light was cut off. A section of wall swung out with the baron’s finger thrust through the hole. The torch held by von Elgers lit the well. Wolff crouched down behind the shadow cast by a turn of the corkscrew case. Presently, the light became weaker as the baron carried it up the steps. Wolff followed.
He could not keep his eyes on von Elgers all the time, for he had to dodge down behind various turns to keep from being detected if the baron should look downward. So it was that he did not see von Elgers leave the stairs nor know it until the light suddenly went out.
He went swiftly after the baron, although he did pause by the peephole. He stuck his finger in it and lifted upward. A small section gave way, a click sounded, and a door swung open for him. The inner side of the door formed part of the wall of the baron’s quarters. Wolff stepped into the room, chose a thin eight-inch dagger from a rack in the wall, and went back out to the stairs. After shutting the door, he climbed upward.
