Three gorillas had fallen before Tarzan's knife, but the fourth seized his wrist and struck at him with the haft of his pike. The ape-man closed; his teeth sought the jugular of his antagonist and fastened there. The brute screamed and sought to tear himself free; then one of his companions stepped in and struck Tarzan heavily across one temple with the butt of a battle axe.
The lord of the jungle sank senseless to the roof amid the victorious shouts of his foemen. The gorilla god pushed forward.
"Do not kill him!" he screamed again.
"He is already dead, My Lord," said one of the gorillas.
The god trembled with disappointment and rage, and was about to speak when the gorilla that had recaptured Rhonda forced its way through the crowd.
"The castle is afire, My Lord!" he cried. "The smudge that was built to smoke out the prisoners spread to the dry grass on the floor of their cell, and now the beams and floor above are all ablaze—the first floor of the castle is a roaring furnace. If you are not to be trapped, My Lord, you must escape at once."
Those who heard him looked quickly about. A dense volume of smoke was pouring from the tower from which Tarzan and Rhonda had come; smoke was coming from other towers nearby; it was rising from beyond the parapet, evidently coming from the windows of the lower floors.
There was instant uneasiness. The gorillas rushed uncertainly this way and that. All beasts are terrified by fire, and the instincts of beasts dominated these aberrant creatures. Presently, realizing that they might be cut off from all escape, panic seized them.
Screaming and roaring, they bolted for safety, deserting their prisoners and their god. Some rushed headlong down blazing stairways to death, others leaped the parapet to an end less horrible, perhaps, but equally certain.
Their piercing shrieks, their terrified roars rose above the crackling and the roaring of the flames, above the screamed commands of their gorilla god, who, seeing himself deserted by his creatures, completely lost his head and joined in the mad rush for safety.
