The Khad Tambur held up a hand. The order was repeated and carried back and the marching column of Mongs came to a gradual halt. Twenty miles of horses, men, and wagons stretched far back into the pass.

Blade and Sadda moved their ponies up to the crest, off to one side of the Khad. No one paid them any attention. The Khad, slumped in his saddle, his malformed back bent half over in constant pain, stared at the scene with his good eye.

Blade, with two excellent eyes, was seeing it differently. This, he knew immediately, would not be easy. He understood why the Sea Caths had not reinforced the fort at the mouth of the pass. They thought themselves secure enough in their city.

Below them the land sloped away to level into a great green plain. Perfect terrain for the Mong horsemen - if the Sea Caths would come out and fight.

They would not be such fools. Blade was sure of it. The city below was perfectly situated for defense. It stood at the mouth of a harbor shaped like an hourglass. An enormous chain, glistening now in the sun, stretched across the narrow waist. The inner harbor was crowded with craft of every description from tiny fishing boats to tall clumsy-looking men of war. They floated placidly at anchor, with no sign of bustle or alarm. As well they might. The Sea Caths had nothing to fear from that direction.

High cliffs ran around the inner harbor, right up to the waterfront of the city. There was no approach that way. The cliffs were effective flank guards. The only feasible line of attack was the direct frontal, across the broad green plain which lay below them. It was inviting - until you got to within two hundred yards of the low city wall.

First there was a wide ditch that sloped gradually down until it met the perpendicular back wall. Blade guessed the wall at twenty feet. From the lip of the ditch to the wall, the slope was covered with sharp-pointed stakes set firmly into the earth and pointing at the lip. Men could move among those stakes. Not horses.

Beyond the ditch - Blade saw immediately and understood, and knew the Mongs would not comprehend - was the trap. The real defensive trickery. A wide moat. Dry now.

Blade traced the moat around the city and his lips twitched in a dry smile. Those were sluice gates where the moat ended in the harbor, and those long poles and levers would open them and let in the sea. A quick glance and rapid calculation convinced him. The sea wall fronting the city was keeping the harbor in its place. Open the sluice gates and gravity would do the rest.

For an hour the Khad and his Captains studied the town and the terrain. Blade saw Rahstum and the Khad in deep debate. Meantime he and Sadda had ridden even more to one side and were safely out of earshot.

Sadda, her knee touching his as the horses stood patiently, said, "We must make ready now, Blade. The time is coming again. I know my brother as few do, and I see signs of the madness returning. Not yet, but soon. And when he takes this city there will be a great feast and celebration. Greater, and wilder than would have been on his birth date. That will be our chance. Be ready."

He masked his eyes and nodded. "I will be ready. I have forgotten nothing and I know what I have to do."

Kill the dwarf after Morpho had killed the Khad! Blade knew it was not going to work out that way, but he still puzzled about how Sadda expected to force the dwarf into killing her brother?

She laid a hand on his, whispering. "I will tell you the other half of my secret now. You will see how clever I have been, and how perfectly everything fits."

A child bragging and wanting praise.

"Before this battle, Blade, I am going to ask the Khad for your freedom, that he let you break the golden collar. He will ask me why, in that sly way of his, and I will tell him truth - up to a point.

"I will say that I have love for you, which is true, and that I mean to marry you. He will shake with rage and scream at me, but in the end I think he will permit it. It has been done before, as I shall remind him. Not often, but royal women have married their slaves before."

Blade was watching her face. She was veiled, as always when they rode abroad, but he had come to read her beneath the veil. Her coronet of black hair glistened in the sun as she leaned to tap his knee with her whip. Her eyes were narrowed in speculation.

"There must be no mention of the child I carry. No one must know of that yet. But you see it, Blade? If my brother permits the marriage, and it is done according to Mong law, then our child is a legal prince or princess. Our marriage is legal. And when he is dead you will sit by me as legal Consort. We will have many children, Blade, and so found a new line of great warriors and conquerors the like of which has never been seen before."

Blade had not thought her so ambitious, and had deemed her much too selfish to be concerned with her posterity. It was another facet of this diamond-hard lady.

The Khad wasted no time in sending a courier to demand the immediate and abject surrender of the Sea Caths. Unconditional surrender! He promised them nothing but their lives, which would then belong to the Mongs.

Meantime the Mongs were on the march again, moving from the pass out onto the broad green plain before the city. They debouched and spread in their thousands, covering the plain like a dark tidal wave. Tents were pitched and fires built and horses slaughtered for food. There was a great furbishing of weapons and much laughter and song. After the bitter defeats at the wall, and the horrible trek over the mountains, the warriors were primed for blood and booty. For killing until they were surfeited with killing. To none, save Blade and possibly Rahstum, did it occur that the attack might be beaten back.

While they waited for the courier's return, the Khad entertained a small party in his tent. Blade was included.

He kept well in the background and watched. The Khad was in high good humor, drinking often of bross, and though Blade could discern no sign of the madness yet he judged that Sadda was right. It was on the way. Now and again the Khad's voice would reach a high pitch, nearly a scream, and his laughter was shrill. He demanded constant entertainment. Belly dancers were summoned, and acrobats and eaters of fire, and Morpho had to run through his entire gamut of tricks. The Khad's beloved melons, packed in snow, had been kept in supply at great expense of time and men, and now the dwarf must throw his voice into a melon and beg, in a whimper, to be eaten by the Scourge of the World.

Morpho performed skillfully, without a glance at Blade, who wondered at the little man's thoughts. As the madness grew the Khad would once again be casting about for little girls. But surely Nantee, in her rags and dung gatherer's filth, would be safe enough.

Seeing the Khad in such high good humor, Sadda leaned and spoke to him from her throne. Blade, noting this, felt himself tense. He knew, even before the Khad crooked a finger at him, that Sadda was beginning to carry out the first part of her plan.

Blade went to the throne and bowed with dignity. His nerves were jumping but he kept his face impassive. He was not, as he well knew, an unimpressive sight. He towered over them all, but Rahstum, and his leather armor was as well fitted and burnished as any. His beard, though kept well trimmed by Baber, bristled fiercely and he wore a sword as though he had been born with it.

After his bow Blade met the Khad's eye without flinching, matching that single orb stare for stare.

"You summon me, Lord of the World? I am at your command."

The single eye narrowed and something fanatic gleamed for a moment, then it widened and the Khad struck his knee and laughed harshly.

"Are you now, Blade? Hah. I had thought you only at the command of my sister - and Obi knows she commands enough of you, eh? How do you fare, Blade? How is it to bed my sister?"

Hate and jealousy in that eye now. The Khad was impotent, except with small girls, and he was remembering.

Blade, walking on eggs, felt them crackling beneath his tread.

He bowed again. "I have no complaint, Khad Tambur. No complaint at all."

There was a moment of silence. Rahstum crossed his arms and stared stonily at Blade. Morpho juggled. The Khad inched his tortured spine forward to peer at Blade. Then he went into a gale of laughter.

"No complaints, eh? No complaints! I think not, Blade, and I know! Or once knew. But it is most generous of you to acknowledge that you have no complaints."

The company, taking their cue, joined in the laughter. They ceased abruptly as the Khad raised a hand.

"Be still, all. I want you to hear this. Hear my sister's request - and hear my answer. She would have me free Blade. Strike the golden collar from his neck! What think you of that?"

Murmurs of puzzlement. None of them knew what to think - the Khad not having yet told them.

The Khad raised his hand again. "But wait. My sister tells me more, makes another request of me, her beloved brother. Would you hear it?"

Assent from the crowd. They knew what was expected.

The Khad, Blade admitted, was not a bad showman. He waited until the murmurs and whispering died away, then went on: "Sadda wishes to marry this man Blade! After he is freed, of course, for no Mong princess can marry a slave. And what think you of that?"

Blade, watching for reaction from Rahstum and the dwarf, saw them glance swiftly at each other, then at him. Their blank faces told him nothing.

The tent was buzzing like a beehive. Everyone was darting glances at Blade and Sadda. He got the impression that some of the company were not too much surprised.

And now madness did flare in the Khad's eye. It glittered at Blade and the Khad's grin was that of a carrion ape.

"I will permit this marriage," the Khad said. "I will free you, Blade, of your collar. After the town of the Sea Catlis has been taken, and after you play a part in taking it. An important part, my friend, for I would have you in the foremost rank!"

Blade bowed and nodded. "That is most generous of you, great Khad. I will try not to disappoint you."

The Khad snarled and pointed to his sister. "Just be sure that you do not disappoint her! I know you are a great warrior, Blade, or so I am constantly told. And I saw you defeat Cossa, so there may be some truth to it. But tomorrow we will see if your victory over my champion was a freak of luck."

Rahstum, without looking at Blade, spoke up. "A wise decision, great Lord. But I would have a favor also. I would have this Blade fight with me and my men, and in the foremost rank as you say. I will give him such a testing as he has never had."
