Then, just as he was about to creep back from that detestable flame, he saw a stirring among the vague dark forms and heard a peculiar and unmistakable sound. It was the frightened meeping of a ghoul, and in a moment it had swelled to a veritable chorus of anguish. Secure as he was in the shadow of monstrous ruins, Carter allowed his curiosity to conquer his fear, and crept forward again instead of retreating. Once in crossing an open street he wriggled worm-like on his stomach, and in another place he had to rise to his feet to avoid making a noise among heaps of fallen marble. But always he succeeded in avoiding discovery, so that in a short time he had found a spot behind a titan pillar where he could watch the whole green-litten scene of action. There around a hideous fire fed by the obnoxious stems of lunar fungi, there squatted a stinking circle of the toadlike moonbeasts and their almost-human slaves. Some of these slaves were heating curious iron spears in the leaping flames, and at intervals applying their white-hot points to three tightly trussed prisoners that lay writhing before the leaders of the party. From the motions of their tentacles Carter could see that the blunt-snouted moonbeasts were enjoying the spectacle hugely, and vast was his horror when he suddenly recognised the frantic meeping and knew that the tortured ghouls were none other than the faithful trio which had guided him safely from the abyss, and had thereafter set out from the enchanted wood to find Sarkomand and the gate to their native deeps.
