The troop halted, and the captain of the guard swaggered forth, a giant with bulging muscles and a henna-stained beard.
"Thy names and business!" he roared, glaring intolerantly at Brent.
"My name you know as well as you know your own," growled Muhammad ez Zahir. "I am taking a prisoner into the city, by order of Abd el Khafid."
"Pass, Muhammad ez Zahir," growled the captain. "But who is this Kurd?"
Muhammad grinned wolfishly, as if at a secret jest.
"An adventurer who seeks admission—Shirkuh, of the Jebel Jawur."
While they were speaking, a richly clad, powerfully built man on a white mare rode out of the gate and halted, unnoticed, behind the guardsmen. The henna-bearded captain turned toward Shirkuh who had dismounted to get a pebble out of his stallion's hoof.
"Are you one of the clan?" he demanded. "Do you know the secret signs?"
"I have not yet been accepted," answered Shirkuh, turning to face him. "Men tell me I must be passed upon by the council of imams."
"Aye, if you reach them! Does any chief of the city speak for you?"
"I am a stranger," replied Shirkuh shortly.
"We like not strangers in Rub el Harami," said the captain. "There are but three ways a stranger may enter the city. As a captive, like that infidel dog yonder; as one vouched for and indorsed by some established chief of the city; or"—he showed yellow fangs in an evil grin—"as the slayer of some fighting man of the city!"
He shifted the rifle to his right hand and slapped the butt with his left palm. Sardonic laughter rose about them, the dry, strident, cruel cackling of the hills. Those who laughed knew that in any kind of fight between a stranger and a man of the city every foul advantage would be taken. For a stranger to be forced into a formal duel with a Black Tiger was tantamount to signing his death warrant. Brent, rigid with sudden concern, guessed this from the vicious laughter.
But Shirkuh did not seem abashed.
"It is an ancient custom?" he asked naively, dropping a hand to his girdle.
"Ancient as Islam!" assured the giant captain, towering above him. "A tried warrior, with weapons in his hands, thou must slay!"
"Why, then—"
Shirkuh laughed, and as he laughed, he struck. His motion was as quick as the blurring stroke of a cobra. In one movement he whipped the dagger from his girdle and struck upward under the captain's bearded chin. The Afghan had no opportunity to defend himself, no chance to lift rifle or draw sword. Before he realized Shirkuh's intention, he was down, his life gushing out of his sliced jugular.
An instant of stunned silence was broken by wild yells of laughter from the lookers-on and the men of the troop. It was just such a devilish jest as the bloodthirsty hill natures appreciated. There is humor in the hills, but it is a fiendish humor. The strange youth had shown a glint of the hard wolfish sophistication that underlay his apparent callowness.
But the other guardsmen cried out angrily and surged forward, with a sharp rattle of rifle bolts. Shirkuh sprang back and tore his rifle from its saddle scabbard. Muhammad and his men looked on cynically. It was none of their affair. They had enjoyed Shirkuh's grim and bitter jest; they would equally enjoy the sight of him being shot down by his victim's comrades.
But before a finger could crook on a trigger, the man on the white mare rode forward, beating down the rifles of the guards with a riding whip.
"Stop!" he commanded. "The Kurd is in the right. He slew according to the law. The man's weapons were in his hands, and he was a tried warrior."
"But he was taken unaware!" they clamored.
"The more fool he!" was the callous retort. "The law makes no point of that. I speak for the Kurd. And I am Alafdal Khan, once of Waziristan."
"Nay, we know you, my lord!" The guardsmen salaamed profoundly.
Muhammad ez Zahir gathered up his reins and spoke to Shirkuh.
"You luck still holds, Kurd!"
"Allah loves brave men!" Shirkuh laughed, swinging into the saddle.
Muhammad ez Zahir rode under the arch, and the troop streamed after him, their captive in their midst. They traversed a short narrow street, winding between walls of mud and wood, where overhanging balconies almost touched each other over the crooked way. Brent saw women staring at them through the lattices. The cavalcade emerged into a square much like that of any other hill town, Open shops and stalls lined it, and it was thronged by a colorful crowd. But there was a difference. The crowd was too heterogeneous, for one thing; then there was too much wealth in sight. The town was prosperous, but with a sinister, unnatural prosperity. Gold and silk gleamed on barefooted ruffians whose proper garb was rags, and the goods displayed in the shops seemed mute evidence of murder and pillage. This was in truth a city of thieves.
The throng was lawless and turbulent, its temper set on a hair trigger. There were human skulls nailed above the gate, and in an iron cage made fast to the wall Brent saw a human skeleton. Vultures perched on the bars. Brent felt cold sweat bead his flesh. That might well be his own fate—to starve slowly in an iron cage hung above the heads of the jeering crowd. A sick abhorrence and a fierce hatred of this vile city swept over him.
As they rode into the city, Alafdal Khan drew his mare alongside Shirkuh's stallion. The Waziri was a bull-shouldered man with a bushy purple- stained beard and wide, ox-like eyes.
"I like you, Kurd," he announced. "You are in truth a mountain lion. Take service with me. A masterless man is a broken blade in Rub el Harami."
"I thought Abd el Khafid was master of Rub el Harami," said Shirkuh.
"Aye! But the city is divided into factions, and each man who is wise follows one chief or the other. Only picked men with long years of service behind them are chosen for Abd el Khafid's house troops. The others follow various lords, who are each responsible to the emir."
"I am my own man!" boasted Shirkuh. "But you spoke for me at the gate. What devil's custom is this, when a stranger must kill a man to enter?"
"In old times it was meant to test a stranger's valor, and make sure that each man who came into Rub el Harami was a tried warrior," said Alafdal. "For generations, however, it has become merely an excuse to murder strangers. Few come uninvited. You should have secured the patronage of some chief of the clan before you came. Then you could have entered the city peacefully."
"I knew no man in the clan," muttered Shirkuh. "There are no Black Tigers in the Jebel Jawur. But men say the clan is coming to life, after slumbering in idleness for a hundred years, and—"
A disturbance in the crowd ahead of them interrupted him. The people in the square had massed thickly about the troop, slowing their progress, and growling ominously at the sight of Brent. Curses were howled, and bits of offal and refuse thrown, and now a scarred Shinwari stooped and caught up a stone which he cast at the white man. The missile grazed Brent's ear, drawing blood, and with a curse Shirkuh drove his horse against the fellow, knocking him down. A deep roar rose from the mob, and it surged forward menacingly. Shirkuh dragged his rifle from under his knee, but Alafdal Khan caught his arm
"Nay, brother! Do not fire. Leave these dogs to me."
He lifted his voice in a bull's bellow which carried across the square.
"Peace, my children! This is Shirkuh, of Jebel Jawur, who has come to be one of us. I speak for him—I, Alafdal Khan!"
A cheer rose from the crowd whose spirit was as vagrant and changeable as a leaf tossed in the wind. Obviously the Waziri was popular in Rub el Harami, and Brent guessed why as he saw Alafdal thrust a hand into a money pouch he carried at his girdle. But before the chief could completely mollify the mob by flinging a handful of coins among them, another figure entered the central drama. It was a Ghilzai who reined his horse through the crowd—a slim man, but tall and broad-shouldered, and one who looked as though his frame were of woven steel wires. He wore a rose-colored turban; a rich girdle clasped his supple waist, and his caftan was embroidered with gilt thread. A clump of ruffians on horseback followed him.
