This lower roof on which they were was but ten feet above the level of the ground; and, using the rope again, it was only a matter of seconds before the two stood in comparative safety between the castle and the towering cliff.
"Come now," said the ape-man; "we will go around to the front of the castle and find out if the girl escaped."
"We shall have to be careful," cautioned the gorilla god. "This fire will have attracted a crowd from the city. I have many enemies in the palace of the king who would be glad to capture us both. Then we should be killed and the girl lost—if she is not already dead."
"What do you suggest, then?" Tarzan was suspicious. He saw a trap, he saw duplicity in everything conceived by the mind of man.
"The fire has not reached this low wing yet," explained the other. "In it is the entrance to a shaft leading down to the quarters of a faithful priest who dwells in a cave at the foot of the cliff on a level with the city. If we can reach him we shall be safe. He will hide us and do my bidding."
Tarzan scowled. He had the wild beast's aversion to entering an unfamiliar enclosure, but he had overheard enough of the conversation between the gorilla god and Cranmer to know that the former's statement was at least partially true—his enemies in the palace might gladly embrace an opportunity to imprison or destroy him.
"Very well," he assented; "but I am going to tie this rope around your neck so that you may not escape me, and remind you that I still have the knife with which I killed several of your gorillas. I and the knife will be always near you."
The gorilla god made no reply; but he submitted to being secured, and then led the way into the building and to a cleverly concealed trap opening into the top of a shaft descending into darkness.
Here a ladder led downward, and Tarzan let his companion precede him into the Stygian blackness of the shaft. They descended for a short distance to a horizontal corridor which terminated at another vertical shaft. These shafts and corridors alternated until the gorilla god finally announced that they had reached the bottom of the cliff.
Here they proceeded along a corridor until a heavy wooden door blocked their progress. The gorilla god listened intently for a moment, his ear close to the planking of the door. Finally he raised the latch and pushed the door silently ajar. Through the crack the ape-man saw a rough cave lighted by a single smoky torch.
