Presently he saw a bull gorilla roll within the range of his vision. The beast carried a pike. Behind him came another similarly armed, and another and another and another until twenty of the great anthropoids were gathered on the castle roof.
They clustered about Cranmer and the gorilla god for a minute or two. The latter was talking to them. Tarzan could recognize the tones if not the words. Then the twenty approached the tower and grouped themselves in a semicircle before the low aperture leading into it.
Both Rhonda Terry and the lord of the jungle were assured that their hiding place was guessed if not known, yet they could not be certain. They would wait. That was all that they could do. However, it was an easy place to defend; and they might remain there awaiting some happy circumstance that would give them a better chance of escape than was presented to them at the moment.
The gorillas on the roof seemed only to be waiting. They did not appear to be contemplating an investigation of the interior of the tower. Perhaps, thought Tarzan, they were there for some other purpose than that which he had imagined. They might have been gathered in preparation for the coming of the king to his death in the morning.
By the parapet stood the gorilla god with the bull called Cranmer. The weird chuckle of the former was the only sound that broke the silence of the night. The ape-man wondered why the thing was chuckling.
A sudden upward draft from the shaft below them brought a puff of acrid smoke and a wave of heat. Tarzan felt the girl clutch his arm. Now he knew why the gorillas waited so patiently before the entrance to the tower. Now he knew why the gorilla god chuckled.

HOLOCAUST
Tarzan considered the problem that confronted him. It was evident that they could not long endure the stifling, blinding smoke. To make a sudden attack upon the gorillas would be but to jeopardize the life of his companion without offering her any hope of escape. Had he been alone it would have been different, but now there seemed no alternative to coming quietly out and giving themselves up.
On the other hand he knew that the gorilla god purposed death for him and either death or a worse fate for the girl. Whatever course he pursued, then, would evidently prove disastrous. The ape-man, seldom hesitant in reaching a decision, was frankly in a quandary.
