That last command was unnecessary. No man in that host could have been bribed to approach that mysterious black silken pavilion, the door-flaps of which were always closely drawn. None but Xaltotun ever entered it, yet voices were often heard issuing from it; its walls billowed sometimes without a wind, and weird music came from it. Sometimes, deep in midnight, its silken walls were lit red by flames flickering within, limning misshapen silhouettes that passed to and fro. Lying in his own tent that night, Amalric heard the steady rumble of a drum in Xaltotun's tent; through the darkness it boomed steadily, and occasionally the Nemedian could have sworn that a deep, croaking voice mingled with the pulse of the drum. And he shuddered, for he knew that voice was not the voice of Xaltotun. The drum rustled and muttered on like deep thunder, heard afar off, and before dawn Amalric glancing from his tent, caught the red flicker of lightning afar on the northern horizon. In all other parts of the sky the great stars blazed whitely. But the distant lightning flickered incessantly, like the crimson glint of firelight on a tiny, turning blade. * * * * * At sunset of the next day Tarascus came up with his host, dusty and weary from hard marching, the footmen straggling hours behind the horsemen. They camped in the plain near Amalric's camp, and at dawn the combined army moved westward. Ahead of him roved a swarm of scouts, and Amalric waited impatiently for them to return and tell of the Poitanians trapped beside a furious flood. But when the scouts met the column it was with the news that Conan had crossed the river! 'What?' exclaimed Amalric. 'Did he cross before the flood?' 'There was no flood,' answered the scouts, puzzled. 'Late last night he came up to Tanasul and flung his army across.' 'No flood?' exclaimed Xaltotun, taken aback for the first time in Amalric's knowledge. 'Impossible! There were mighty rains upon the headwaters of the Shirki last night and the night before that!' 'That may be your lordship,' answered the scout. 'It is true the water was muddy, and the people of Tanasul said that the river rose perhaps a foot yesterday; but that was not enough to prevent Conan's crossing.' Xaltotun's sorcery had failed! The thought hammered in Amalric's brain. His horror of this strange man out of the past had grown steadily since that night in Belverus when he had seen a brown, shriveled mummy swell and grow into a living man. And the death of Orastes had changed lurking horror into active fear. In his heart was a grisly conviction that the man--or devil--was invincible. Yet now he had undeniable proof of his failure.
