Question: After what seemed an eternity to Tibo, they arrived at the mouth of a cave between two rocky hills. The opening was low and narrow. A few saplings bound together with strips of rawhide closed it against stray beasts. Bukawai removed the primitive door and pushed Tibo within. The hyenas, snarling, rushed past him and were lost to view in the blackness of the interior. Bukawai replaced the saplings and seizing Tibo roughly by the arm, dragged him along a narrow, rocky passage. The floor was comparatively smooth, for the dirt which lay thick upon it had been trodden and tramped by many feet until few inequalities remained. The passage was tortuous, and as it was very dark and the walls rough and rocky, Tibo was scratched and bruised from the many bumps he received. Bukawai walked as rapidly through the winding gallery as one would traverse a familiar lane by daylight. He knew every twist and turn as a mother knows the face of her child, and he seemed to be in a hurry. He jerked poor little Tibo possibly a trifle more ruthlessly than necessary even at the pace Bukawai set; but the old witch-doctor, an outcast from the society of man, diseased, shunned, hated, feared, was far from possessing an angelic temper. Nature had given him few of the kindlier characteristics of man, and these few Fate had eradicated entirely. Shrewd, cunning, cruel, vindictive, was Bukawai, the witch-doctor. <sep>Who knew every twist and turn of the gallery?<sep>Bukawai

Answer: Yes
