Luke Soames, buttoning up his black coat, stood in the darkness, listening.  
His constitutional distaste for leaping blindfolded had been over-ridden by circumstance. He felt himself to be a puppet of Fate, and he drifted with the tide because he lacked the strength to swim against it. That will-o'-the-wisp sense of security which had cheered him when first he had realized how much he owed to the protective wings of Mr. King had been rudely extinguished upon the very day of its birth; he had learnt that Mr. King was a sinister protector; and almost hourly he lived again through the events of that night when, all unwittingly, he had become a witness of strange happenings in the catacombs.
 
Soames had counted himself a lost man that night; the only point which he had considered debatable was whether he should be strangled or poisoned. That his employers were determined upon his death, he was assured; yet he had lived through the night, had learnt from his watch that the morning was arrived... and had seen the flecks at the roots of his dyed hair, blanched by the terrors of that vigil—of that watching, from moment to moment, for the second coming of Ho-Pin.
 
Yes, the morning had dawned, and with it a faint courage. He had shaved and prepared himself for his singular duties, and Said had brought him his breakfast as usual. The day had passed uneventfully, and once, meeting Ho-Pin, he had found himself greeted with the same mirthless smile but with no menace. Perhaps they had believed his story, or had disbelieved it but realized that he was too closely bound to them to be dangerous.
 
Then his mind had reverted to the conversation overheard in the music-hall. Should he seek to curry favor with his employers by acquainting them with the fact that, contrary to Gianapolis' assertion, an important clue had fallen into the hands of the police? Did they know this already? So profound was his belief in the omniscience of the invisible Mr. King that he could not believe that Power ignorant of anything appertaining to himself.
 
Yet it was possible that those in the catacombs were unaware how Scotland Yard, night and day, quested for Mr. King. The papers made no mention of it; but then the papers made no mention of another fact—the absence of Mrs. Leroux. Now that he was no longer panic-ridden, he could mentally reconstruct that scene of horror, could hear again, imaginatively, the shrieks of the maltreated woman. Perhaps this same active imagination of his was playing him tricks, but, her voice... Always he preferred to dismiss these ideas.
 
He feared Ho-Pin in the same way that an average man fears a tarantula, and he was only too happy to avoid the ever smiling Chinaman; so that the days passed on, and, finding himself unmolested and the affairs of the catacombs proceeding apparently as usual, he kept his information to himself, uncertain if he shared it with his employers or otherwise, but hesitating to put the matter to the test—always fearful to approach Ho-Pin, the beetlesque.
 
But this could not continue indefinitely; at least he must speak to Ho-Pin in order to obtain leave of absence. For, since that unforgettable night, he had lived the life of a cave-man indeed, and now began to pine for the wider vault of heaven. Meeting the impassive Chinaman in the corridor one morning, on his way to valet one of the living dead, Soames ventured to stop him.
 
“Excuse me, sir,” he said, confusedly, “but would there be any objection to my going out on Friday evening for an hour?”
 
“Not at all, Soames,” replied Ho-Pin, with his mirthless smile: “you may go at six, wreturn at ten.”
 
Ho-Pin passed on.
 
Soames heaved a gentle sigh of relief. The painful incident was forgotten, then. He hurried into the room, the door of which Said was holding open, quite eager for his unsavory work.
 
In crossing its threshold, he crossed out of his new peace into a mental turmoil greater in its complexities than any he yet had known; he met M. Gaston Max, and his vague doubts respecting the omniscience of Mr. King were suddenly reinforced.
 
Soames' perturbation was so great on that occasion that he feared it must unfailingly be noticed. He realized that now he was definitely in communication with the enemies of Mr. King! Ah; but Mr. King did not know how formidable was the armament of those enemies! He (Soames) had overrated Mr. King; and because that invisible being could inspire Fear in an inconceivable degree, he had thought him all-powerful. Now, he realized that Mr. King was unaware of the existence of at least one clue held by the police; was unaware that his name was associated with the Palace Mansions murder.
 
The catacombs of Ho-Pin were a sinking ship, and Soames was first of the rats to leave.
 
He kept his appointment at the “Three Nuns” as has appeared; he accepted the blood-money that was offered him, and he returned to the garage adjoining Kan-Suh Concessions, that night, hugging in his bosom a leather case containing implements by means whereof his new accomplice designed to admit the police to the cave of the golden dragon.
 
Also, in the pocket of his overcoat, he had a neat Browning pistol; and when the door at the back of the garage was opened for him by Said, he found that the touch of this little weapon sent a thrill of assurance through him, and he began to conceive a sentiment for the unknown investigator to whom he was bound, akin to that which formerly he had cherished for Mr. King!
 
Now the time was come.
 
The people of the catacombs acquired a super-sensitive power of hearing, and Soames was able at this time to detect, as he sat or lay in his own room, the movements of persons in the corridor outside and even in the cave of the golden dragon. That mysterious trap in the wall gave him many qualms, and to-night he had glanced at it a thousand times. He held the pistol in his hand, and buttoned up within his coat was the leather case. Only remained the opening of his door in order to learn if the lights were extinguished in the corridor.
 
He did not anticipate any serious difficulty, provided he could overcome his constitutional nervousness. In his waistcoat pocket was a brand new Yale key which, his latest employer had assured him, fitted the lock of the end door of Block A. The door between the cave of the dragon and Block A was never locked, so far as Soames was aware, nor was that opening from the corridor in which his own room was situated. Therefore, only a few moments—fearful moments, certainly—need intervene, ere he should have a companion; and within a few minutes of that time, the police—his friends!—would be there to protect him! He recognized that the law, after all, was omnipotent, and of all masters was the master to be served.
 
There was no light in the corridor. Leaving his door ajar, he tiptoed cautiously along toward the cave. Assur............
