Presently he became aware of vague noises somewhere in the distance. He fancied he heard shots fired and a loud tumult of voices.
He thought it might be imagination, but suddenly the sounds increased, and once or twice footsteps hurried past the dungeon. The noise now woke Melton, and together they listened, convinced that it was a presentiment of coming evil. The strange sounds rose and fell, at times nearly dying away and then bursting out with renewed violence.
"I can't understand it at all," said Guy. "It can't be a rejoicing over the capture of Zaila, for they are plainly cries of anger."
"We'll know pretty soon what it means," returned Melton; "it concerns us, you may be sure."
In his excitement he arose and began to pace the floor. His wound was giving him no pain, he said, adding that he really felt pretty well again.
At last the shouts seemed to come a little nearer, and before long the fierce, angry cries were heard close at hand.
"They are surrounding the prison," said Guy, huskily.
He was right. A howling mob was on all sides of them now, and it was quite clear that they were beginning to attack the walls of the courtyard, for suddenly half a dozen shots were fired as though the guards were resisting the invaders.
It was a period of terrible suspense. The shouts increased, the firing grew heavier, powder-smoke drifted into the prison; but just when they expected to see their dungeon door torn open by a mad swarm of fanatics the uproar suddenly ceased.
A full minute of silence followed, and then on the night air rose a howl of triumph, so savage, so vindictive, that Guy and Melton shivered from head to foot. For some reason the attack had been suddenly abandoned. What that reason was they could only surmise.
