"There's nothing wrong with me; but I'm in a desperate hurry!" cried Jim again. "Bring your gun, and come along quickly, for we haven't a moment to lose."

"But the prisoner, your father?"

"He's here. I've managed to get him safely out of his cell, and now we must fly for our lives. Ah——"

At that moment Jim became aware of the fact that a tall figure was rushing down upon them from the direction of the Mullah's house, and instantly realized that it must be the sentry who for a short period of time had claimed him as a comrade that evening. Already the man was within a few paces of him, and, with lowered spear-point, and shield held well forward so as to protect his body, came headlong towards them.

"Look out!" shouted John Margetson.

But Jim needed no warning, for, hazardous though the position was, he had never for one moment allowed his coolness to desert him. Without moving, therefore, from the spot upon which he stood, he turned slightly, and whipping the revolver from his waistcloth, levelled it at the advancing sentry. Click! Back went the lock as he gave the first pressure upon the trigger. Snap! The hammer fell; but there was no explosion, no bullet flew from the muzzle, for by an evil chance a splash of the river had damped the cap.

Undaunted, however, Jim gave vent to an exclamation of annoyance, and then, without lowering his arm, jerked at the trigger again. Bang! This time the hammer had fallen upon an undamaged cartridge. Jim heard the bullet strike the man's breast, and then, ere the flash of the powder had died down, he saw him suddenly plunge forward, with arms thrown out before him, while spear and shield were cast high into the air. A second later, with a clatter which could be heard all over the village, the muscular figure of the unfortunate sentry came crashing to the ground, where it lay motionless.

And now the Mullah's village, which a moment before had been peacefully slumbering, was suddenly plunged into a state of wildest turmoil. A very pandemonium seemed to have broken loose, for in all directions doors were flung wide open with a series of resounding bangs, while loud voices rent the silence of the night. Then, just as had happened on a previous evening, a tall figure suddenly appeared beside the flagstaff which stood upon the roof of the central dwelling, and the voice of the Mullah rang out clearly, drowning every other sound.

"Catch them!" he shouted. "After them, every one of you! For if these impudent dogs escape this time we shall be for ever disgraced. Follow them, I say! Pick up their tracks, and when you have done so, I myself will lead you."

"Come down, then, and show us the way now!" called out one of the few men who had been left in the village. "We can see no sign of them, though here, in front of the store-hut, are the bodies of two of our comrades."
