Then that second, prying, stand-aside self was banished by the Captain of raiders as Simon caught sight of a branch of a tree, warped by mountain storms, as yet lacking leaves. It was stark against the afternoon sky and the burden it bore, dangling in small, neatly fashioned loops, was starker yet.

He spurred ahead and sat gazing up at the three small bodies swaying in the breeze, the gaping beaks, the glazed eyes, the dangling, crooked claws still bearing their bracelets of scarlet jesses and small, silvery discs. Three of the true falcons, their necks wrung, left to be found by the next traveler along the way. “Why?” Caluf asked.

“A warning, maybe, or something more.” Simon dismounted and tossed his reins to the other. “Wait here. If I am not back within a reasonable time, return to Ingvald and report. Do not follow, we cannot afford to waste men uselessly.”

Both men protested, but Simon silenced them with a decisive order before he entered the brush. There was evidence in plenty of those who had been there, broken twigs, scraps of boots on moss, a piece of torn jess strap. He was moving closer to the shore; the sound of the surf could be heard, and what he sought had certainly come from the cove.

Simon had been over that path twice, and he set himself to recall a mental picture of the country. Unfortunately the small valley which gave on the shore was lacking in cover. And the crags on either side were as bald. He would have to try one of those, which meant a roundabout route and some tough climbing. Doggedly he got to it.

As he had crept up to Volt’s Hole so did he travel now, crevice, ledge, hand and foothold. Then he crawled on his belly to the edge and looked down into the cove.

Simon had expected many things — a bare strip of sand with no sign of any invasion, a party from Karsten, an anchored ship. But what he saw was very different. At first he thought of the illusions of Estcarp — could what lay below be projected from his own mind, some old memory brought to life for his bafflement? Then a closer inspection of that sharp, clean curve of metal told him that, while it bore some faint resemblance to craft he had known, this was as different from anything in his previous experience as the counterfeit hawk was from the real.

The thing was clearly a sea-going craft, though it had no sign of any superstructure, mast, or method of propulsion. Sharply pointed both fore and aft, it was shaped as might be a cross section, taken length-wise, of a torpedo. There was an opening on its flat upper surface and men stood by that, three of them. The outline of their heads against the silver sheen of the ship were those of the Falconer bird helms. But Simon was equally sure no true Falconers wore them.

Once again the eternal mystery of this land, for the traders’ ships at Sulcarkeep had been masted vessels of a nonmechanical civilization; this ship could be taken out of the future of his own world! How could two so widely differing levels of civilization exist side by side?

Were the Kolder responsible here also? Alien, alien — once more he was on the very verge of understanding — of guessing—

And for that instant he relaxed his vigilance. Only a stout helm plundered from Karsten stores saved his life. The blow which struck at him out of nowhere dazed Simon. He smelled wet feathers, something else — half blinded and dizzy he tried to rise — to be struck again. This time he saw the enemy wing out to sea. A falcon, but true or false? That question he carried with him into the black cloud which swallowed him up.

The throbbing beat of a pain drum filled his skull, shaking on through his body. At first, Simon, returning reluctantly to consciousness, could only summon strength enough to endure that punishment. Then he knew that the beat was not only inside him, but without also. That on which he lay shook with a steady rhythmic pound. He was trapped in the black heart of a tom-tom.

When he opened his eyes, there was no light, and when he tried to move Simon speedily discovered that his wrists and ankles were lashed.

The sensation of being enclosed in a coffin became so overpowering that he had to clamp teeth on lips to prevent crying out. And he was so busy fighting his own private war against the unknown that it was minutes before he realized that wherever he might be, he was not alone in captive misery.

To his right someone moaned faintly now and again. On his left another retched in abject sickness, adding a new stench to the thick atmosphere of their confinement. Simon, oddly reassured by those sounds, unpromising as they were, called out:

“Who lies there? And where are we; does anyone know?”

The moaning ended in a quick catch of breath. But the man who was sick either could not control his pangs, or did not understand.

“Who are you?” That came in a weak trail of whisper from his right.

“One from the mountains. And you? Is this some Karsten prison?”

“Better that it were, mountain man! I have lain in the dungeons of Karsten. Yes, I have been in the question room of such a one. But better there than here.”

Simon was busy sorting out recent memories. He had climbed to a cliff top to spy upon a cove. There had been that strange vessel in harbor there, then attack from a bird which might not have been a bird at all!

Now it added up to only one answer — he lay in the very ship he had seen!

“Are we in the hands of the man-buyers out of Gorm?” he asked.

“Just so, mountain man. You were not with us when those devils of Yvian’s following gave us to the Kolder. Are you one of the Falconers they snared later?”

“Falconers! Ho, men of the Winged Ones!” Simon raised his voice, heard it echo hollowly back from unseen walls.”How many of you lie here? I, whom am of the raiders, ask it!”

“Three of us, raider. Though Faltjar was borne hither limp as a death-stricken man, and we do not know if yet he lives.”

“Faltjar! The guard of the southern passes! How was he taken — and you?”

“We heard of a cove where ships dared land and there was a messenger from Estcarp saying that perhaps supplies might be sent to us by sea if such could be found. So the Lord of Wings ordered us to explore. And we were struck down by hawks as we rode. Though they were not our hawks who battled for us. Then we awoke on shore, stripped of our mail and weapons, and they brought us aboard this craft which has no like in the world. I say that, who am Tandis and served five years as a marine to Sulcarmen. Many ports have I seen and more ships than a man can count in a week of steady marking, yet none kin to this one.”

“It is born of the witchery of Kolder,” whispered the weak voice on Simon’s right. “They came, but how can a man reckon time when he is enclosed in the dark without end? Is it night or day, this day or that? I lay in Kars prison because I offered refuge to a woman and child of the old race when the Horning went forth. They took all of us who were young from that prison and brought us to a delta island. There we were examined.”

“By whom?” Simon asked eagerly. Here was some one who might have seen the mysterious Kolder, from whom he might be able to get some positive information concerning them.

“That I cannot remember.” The voice was the merest thread of sound now and Simon edged himself as far as he could in his bonds to catch it at all. “They work some magic, these men from Gorm, so that one’s head spins around, spilling all thoughts out of it. It is said that they are demons of the great cold from the end of the world, and that I can believe!”

“And you, Falconer, did you look upon those who took you?”

“Yes, but you will have little aid from what I saw, raider. For those who brought us here were Karsten men, mere husks without proper wits — hands and strong backs for their owners. And those owners already wore the trappings they had taken from our backs, the better to befool our friends.”
