Tony’s conscience said bitterly that since he was going to be killed anyhow, he might as well make a fight for it; but if he’d only listened at any single instant since Mr. Emurian offered him two thousand dollars for that ten-dirhim piece—

He swore softly. He felt singularly absurd, standing in the middle of a dusty, sandy plain with a cigarette lighter clutched in his hand, two small stones in his pocket, and with a multitude of lunatic shapes watching intently from the mountainsides about, and misty, ghost-like whirlwinds spinning expectantly beyond them.

For a long time, nothing happened.

“War of nerves,” he muttered indignantly.

The small stone which was Abdul quivered, and seemed to inflate like a balloon. Abdul appeared in his customary shape, very much agitated.

“Lord! Do you see him?”

“Not yet,” growled Tony. “I suppose he’ll fly to contact as a mosquito and then materialize as a boa-constrictor at close quarters. Stand clear if he does.”

“He cannot do it, lord,” said Abdul, nervously. “He can take the shape of an insect, but as an insect he will be too heavy to fly. Our weight is the same regardless of our size, lord.”

“Good!” said Tony, gratified. “Then in sand like this he can’t crawl up as a centipede, either. He’d bog down.” Abdul wrung his hands.

“I spoke too soon when I offered you my allegiance,” he said bitterly. “It is my opinion, lord, that he will fly to a great height as a giant bird—he will need great wing-spread to fly—and then turn to a stone and drop upon you. That is an accepted form of combat.”

“Hm… thanks,” said Tony. “If anything else occurs to you, by all means mention it.”

Abdul began to shrink. He wailed again:

“I spoke too soo—”

He was a stone once more. Tony could not possibly identify him among the other small stones scattered about. He began to search the sky, and remembered to wet his finger again and recheck the wind direction. There was very little movement of air, but he walked downwind from Abdul and snapped open his cigarette lighter. Lasf, as prepared in Barkut, had a distinct, slightly aromatic odor. Tony surrounded himself with a faint fragrance of the stuff. He could smash one of the phials of lasf yet remaining and make himself effectually unapproachable by Es-Souk. But he would certainly have to walk home if he did. And besides, Es-Souk could pick up stones and drop them, bomber-fashion, as easily as he could drop himself. Apparently, though, that was not an accepted form of combat. It appeared that djinns were so endowed that they could make anything they chose out of themselves, and therefore did not need to think of using inanimate things. It would not be good strategy to make Es-Souk so desperate that he might begin to have ideas.

And still nothing happened. There was what seemed to be a single dark bird in the sky, far away over the mountain tops. Tony wondered how far away. The larger a pair of wings might be, the more slowly they would tend to flap. Tony watched. The great bird’s wings went downward only once in five seconds—it took five seconds for them to make their downward sweep, and recover, and begin another stroke. It looked as if it were flying in slow motion. Therefore the bird was very large, and very far away.

Tony nodded his head. At a guess, Es-Souk had adopted the outward form of a roc, and would gain an altitude of some ten or twelve thousand feet in that shape.

Then he might transform himself into a heavy small stone and try to brain Tony. But it wasn’t likely that, as a stone, he could see where he was going or correct his line of fall once he was started. Even U.S. Army bombers, equipped with bombsights, suffered a certain amount of dispersion in their shots.

Inspiration struck Tony. He took off the camel’s-hair, belted-in-the-back topcoat. When in human form, djinns wore clothes—when they remembered. Nasim was apt to be forgetful. But the clothes they created were a part of them, like their jewels and their weapons. They might know the theory of clothing, but in practice for Tony to take off his topcoat might confuse Es-Souk. He mightn’t know whether to aim at the coat or at Tony himself. And besides, if that slowly flapping bird was a roc, and if the roc was Es-Souk, he probably couldn’t see too clearly at the height he’d obtained. Tony draped his coat over a small, sparsely leaved bush that startlingly grew in the middle of this waste. He stood back. He was giving Es-Souk two targets to choose from, and the need for choice might be upsetting.

Apparently, it was. The great bird soared in circles for minutes. Then it dived lower, for a better look. Tony stood as still as his topcoat. He could see the shape of the huge flying thing. It was like a giant eagle, only vastly more terrifying. Its body would be seventy or eighty feet long. Its wings would have the spread of a four-motored bomber. Its claws would have the grip of half a dozen steam shovels in one. And its talons would be needle-sharp and more than three feet long. Decidedly, at close quarters, it wouldn’t be anything to argue with.

It vanished. Completely. Es-Souk had turned himself into a small round stone hurtling downward from the sky.

Tony counted:

“One—two—three—”

Give the stone time to pick up speed in free fall. The time a parachuting flier waits before he opens his parachute.

“Eight—nine—ten— Geronimo! ” said Tony.

He ran like the devil for fifty yards, stopped, and watched the spot where he had been. Then his jaw dropped open. His topcoat was running like the devil, too. The bush on which he had draped it was in full flight. As he stared, he saw the twinkling of pink legs under it. Then his topcoat stopped, and turned, and he saw Nasim in human form inside it. She waved gaily to him.

“Hello!” she called brightly. “I’m helping, too!”

WHOOOOOSH!

Something smacked the desert a mighty blow. Dust arose as from a bomb explosion. A concussion wave spread out with such power that Tony felt a puff of wind, and the topcoat went sailing from around Nasim. She had been forgetful again. She went after the coat and picked it up, swinging it cheerily in one hand as she turned to watch.

Es-Souk arose from the crater which he had made as a stone. He had a new form. He was huge and—now—black and terrible to behold. He was a giant of ebony flesh with four-foot tusks and hands whose clawed fingertips were feet in length.

Tony ran toward him, blowing on the wick of the cigarette lighter.

The giant bellowed, but Tony sprinted even faster for hand-to-hand contact. And the djinn could not quite take it. Tony’s challenge had included so furious an insult to the entire djinn nation that it could not possibly be a bluff—and now his confident rush to close in on Es-Souk was daunting.

Es-Souk spurted upward into a whirlwind half a mile high. He materialized as a roc at the top of the column of misty whirling air. The rest of the whirlwind flashed upward to be absorbed in the bird’s body. It was an admirable technical solution of the problem of a quick take-off for so large a flying creature. Gigantic flappings of mighty pinions sent the roc soaring away. Es-Souk was uncertain. He did not quite know what to do. To cover his indecision, he suddenly swooped and made what looked like a dive-bomber plunge for Tony.

It was utterly horrible to watch. The monstrous creature, its incredibly curved beak gaping, plunged for him in ravening ferocity. Its claws were stretched to rend and tear. It was as perfectly calculated to inspire panic as any sight could possibly be.

Tony faced it. He had a phial of lasf in his handkerchief, now. In the handkerchief, too, were the small stones he’d pocketed. He held the cigarette lighter in his left hand. His right gripped that singularly innocuous bomb. At the last instant he’d squeeze, crush the phial between the stones, and hurl the dripping handkerchief—weighted by the stones—deep into the gaping throat. He didn’t know how quickly it would work, but—

The roc zoomed just as Tony was sending the message to his fingers to tense and smash the lasf -phial. The great wings beat horrifically. Sand rose in clouds about Tony, blinding him. He found himself almost buried to his knees as the sand settled about him.

The roc was flapping into the sky again. Nasim ran up to Tony, beaming and offering him the coat.

“You’re wonderful!” she said adoringly. “What are you going to do next? And what do you want me to do?” He said indignantly:

“You shouldn’t mix into a private fight like this, Nasim!”

“Oh, do let me help!” she pleaded.

“Hell!” said Tony. “Put on something! Put on the coat! How do you expect me to keep my mind on fighting?”

The roc which was Es-Souk made a steep, banking turn. It power-dived at Tony again. And this time Es-Souk had a purpose, a new purpose. He’d seen Tony struggling up out of the sand. So Es-Souk came back only yards above the desert’s surface, his monstrous wings beating almost straight back to give him the absolute maximum of speed. Then, only fifty feet from Tony, he swept his wings violently ahead, and not only checked his own speed and sent himself hurtling upward, but set up such a furious smother of swirling sand that Tony was buried breast-deep before he realized what was happening. Es-Souk had made a sizable sand dune with one stroke of his mighty roc’s wings. It was sheer fortune that its deepest part did not overwhelm Tony.

He worked his way clear, Nasim pulling anxiously at him—with the topcoat lost again. Tony swore furiously. Something like a bubble appeared in the sand dune’s flank. Abdul appeared and arose, with sand grains dripping from his turban. He sputtered and wailed:

“I know I spoke too soon!… Lord! Next time he will bury you, and you will smother, and then what will I do?”

Es-Souk whirled again, low down, and shot back toward Tony again. Nasim said firmly:

“Don’t be so stupid, Abdul! Turn yourself into a griffin, with a saddle, and let him ride you to fight Es-Souk in the air!”

Abdul blinked and hastily drew a deep breath. He expanded, to a large round object with no identifiable features. He contracted to something that Tony could not identify, and which at the moment he did not examine. He saw wings and a saddle and a long, serpentine tail. He made a dash for the saddle, swung into it, and hung on.
