`` If this Koj Burton suspects who we are , do you not think , Appoyas , that he may also have gained some idea of the Cave of Hydas ? '' a voice asked . `` It may be so , and we will have the cave well guarded . Do not forget that to-morrow night at ten o'clock it will be , according to the records , exactly fifty years since the offerings in the Temple of Atlas were removed to the Temple of Hydas . This has been done every fifty years , and only on those occasions is the inner temple opened , and -- '' the speaker stopped abruptly , and then , after a moment 's pause , continued -- `` and , brothers , you may now go . '' On hearing the last words so suddenly spoken the Fakir began quickly and noiselessly to retreat along the passage , but , as no one appeared to be following , he stopped . For some minutes he heard men talking , and dimly saw some figures come into the passage and go in the opposite direction , and in a short time the sound of footsteps died away and the Fakir was left alone in the silent darkness .
