“ A long-stemmed key on the ring fitted the keyhole, but before Finnerty could shoot the bolt the native whispered: "Not yet, sahib." He produced two candles and a box of matches. "Remember, sahib, that no man owns the light of a fire; here is an eye that makes no betraying light." And he placed in Finnerty's fingers a slim male-bamboo rod.At a twist from Finnerty's hand a heavy bolt in the lock glided back with noiseless ease; a pull caused the stone-faced door to swing forward in the same frictionless quiet, and beyond was a gloom as deep as that of the cave. ”
