When night had fallen Tarzan donned the mask and the dead tail of the priest he had slain in the vaults beneath the temple. He judged that it would not do to attempt again to pass the guard, especially so late at night as it would be likely to arouse comment and suspicion, and so he swung into the tree that overhung the garden wall and from its branches dropped to the ground beyond.

Avoiding too grave risk of apprehension the ape–man passed through the grounds to the court of the palace, approaching the temple from the side opposite to that at which he had left it at the time of his escape. He came thus it is true through a portion of the grounds with which he was unfamiliar but he preferred this to the danger of following the beaten track between the palace apartments and those of the temple. Having a definite goal in mind and endowed as he was with an almost miraculous sense of location he moved with great assurance through the shadows of the temple yard.

Taking advantage of the denser shadows close to the walls and of what shrubs and trees there were he came without mishap at last to the ornate building concerning the purpose of which he had asked Lu-don only to be put off with the assertion that it was forgotten - nothing strange in itself but given possible importance by the apparent hesitancy of the priest to discuss its use and the impression the ape–man had gained at the time that Lu-don lied.

And now he stood at last alone before the structure which was three stories in height and detached from all the other temple buildings. It had a single barred entrance which was carved from the living rock in representation of the head of a GRYF, whose wide-open mouth constituted the doorway. The head, hood, and front paws of the creature were depicted as though it lay crouching with its lower jaw on the ground between its outspread paws. Small oval windows, which were likewise barred, flanked the doorway.
