The head was wedge-shaped and made of steel, with sword-sharp edges. Sudanese tribesmen had no such arrows. Even Mamelukes had only a few. Each Mameluke carried two or three, to use against a well-armored opponent.

"Oh, God, help me find Nicetas," he prayed.

Nicetas was out there somewhere. Daoud pushed out of his mind the thought that he might be dead.

Was this punishment for their sin of loving each other, he wondered as he mounted his little horse. God frowned on men lying with men, the mullahs said, but everyone knew that men, especially young men far from women, often took comfort in one another.

He pulled his burnoose farther down over his eyes to shade them better against the sun. He wanted water, but he would not let himself drink until he had reached the hills. He might find Nicetas there, and Nicetas might need the water.

The hills thrust abruptly out of the sand in long vertical folds. Half blinded by the glare, he could see only opaque blackness where the sun did not strike them.

He thought he saw movement in one shadow. He kicked the pony, driving it to struggle faster through the sand, keeping his eyes fixed on the spot.

A deep crevice sliced into the hillside. Daoud rode into it cautiously. Whoever killed Nicetas's mount might still be somewhere about.

Once out of the sun, he slid down from the saddle. He saw no water, but there was a dead tamarisk, its branches like supplicating arms, at the mouth of the crevice. He tied the pony to a limb and moved, slowly, deeper into the shadow.

He looked down at the floor of the crevice, paved with drifting sand and tiny pebbles. He felt a pain in his heart as he saw a trail of dark circular spots, each about the size of his hand. It could be a wounded animal, he told himself.
