That almost superstitious respect for the powers of Sin Sin Wa, which had led Chief Inspector Kerry to look upon the Chinaman as a being more than humanly endowed, began to take possession of Seton Pasha.  He regretted having entered the place so overtly, he regretted having shown a light.  Keen eyes, vigilant, regarded him.  It was perhaps a delusion, bred of the mournful night sounds, the gloom, and the uncanny resourcefulness, already proven, of the Kazmah group.  But it operated powerfully.

Theories, wild, improbable, flocked to his mind.  The great dope cache lay beneath his feet—­and there must be some hidden entrance to it which had escaped the attention of the search-party.  This in itself was not improbable, since they had devoted no more time to this building than to any other in the vicinity.  That wild cry in the night which had struck so mournful a chill to the hearts of the watchers on the river had seemed to come out of the void of the blackness, had given but slight clue to the location of the place of captivity.  Indeed, they could only surmise that it had been uttered by the missing woman.  Yet in their hearts neither had doubted it.

He determined to cause the place to be searched again, as secretly as possible; he determined to set so close a guard over it and over its approaches that none could enter or leave unobserved.

Yet Kismet, in whose omnipotence he more than half believed, had ordained otherwise; for man is merely an instrument in the hand of Fate.

CHAPTER XL

COIL OF THE PIGTAIL

The inner room was in darkness and the fume-laden air almost unbreathable.  A dull and regular moaning sound proceeded from the corner where the bed was situated, but of the contents of the place and of its other occupant or occupants Kerry had no more than a hazy idea.  His imagination supplied those details which he had failed to observe.  Mrs. Monte Irvin, in a dying condition, lay upon the bed, and someone or some thing crouched on the divan behind Kerry as he lay stretched upon the matting-covered floor.  His wrists, tied behind him, gave him great pain; and since his ankles were also fastened and the end of the rope drawn taut and attached to that binding his wrists, he was rendered absolutely helpless.  For one of his fiery temperament this physical impotence was maddening, and because his own handkerchief had been tied tightly around his head so as to secure between his teeth a wooden stopper of considerable size which possessed an unpleasant chemical taste and smell, even speech was denied him.
