"Do not tell me my duty," said Mahmoud. "Have you forgotten what my cane feels like?"

"You would use the cane on me?" Daoud exclaimed, outraged. "When Kassar is cheating?"

There were a thousand tiny wrinkles around Mahmoud's blue Circassian eyes, from a lifetime of squinting into the sun.

"Daoud, I will tell you what my duty is. My duty is to take miserable julbans and make Mamelukes of you. When you are a full-fledged Mameluke, there will be no naqeeb over you to right your wrongs. Among Mamelukes, he who is strongest rules. If Kassar is the strongest among you, you must be ruled by him."

Daoud growled with disgust and ran back to the fight.

Nicetas had somehow gotten back on his feet, though his face was a mass of blood and dirt and his breath was coming in gasps. His eyes were glazed, but he managed to stagger forward and hit Kassar in the nose with his fist. Blood began to flow from the young Tartar's wide nostrils into his mustache.

Kassar put his fingers to his upper lip, took them away and stared at the blood. His eyes widened in fury. His head swung right and left; then he sidestepped to a boy in front of the circle. From the boy's sash he pulled a dabbus, a fluted iron cylinder mounted on a wooden staff.

Swinging the dabbus so it whistled through the air, Kassar charged at Nicetas. The boys fell back, opening the circle wider.

For the first time, Daoud saw fear in Nicetas's eyes. He ducked as Kassar swung the mace at his head, but his movements were slow and awkward. He had been hit too many times. He fell, stood up, and staggered backward.

The naqeeb would not interfere. This could end only one way.
