For a habitual opium-smoker to abstain when the fumes of chandu actually reach his nostrils is a feat of will-power difficult adequately to appraise. An ordinary tobacco smoker cannot remain for long among those who are enjoying the fragrant weed without catching the infection and beginning to smoke also. Twice to redouble the lure of my lady Nicotine would be but loosely to estimate the seductiveness of the Spirit of the Poppy; yet Sir Lucien Pyne smoked one pipe with Mrs. Sin, and perceiving her to be already in a state of dreamy abstraction, loaded a second, but in his own case with a fragment of cigarette stump which smouldered in a tray upon the table. His was that rare type of character whose possessor remains master of his vices.  
Following the fourth pipe—Pyne, after the second, had ceased to trouble to repeat his feat of legerdemain, “The sleep” claimed Mrs. Sin. Her languorous eyes closed, and her face assumed that rapt expression of Buddha-like beatitude which Rita had observed at Kilfane's flat. According to some scientific works on the subject, sleep is not invariably induced in the case of Europeans by the use of chandu. Loosely, this is true. But this type of European never becomes an habitue; the habitue always sleeps. That dream-world to which opium alone holds the key becomes the real world “for the delights of which the smoker gladly resigns all mundane interests.” The exiled Chinaman returns again to the sampan of his boyhood, floating joyously on the waters of some willow-lined canal; the Malay hears once more the mystic whispering in the mangrove swamps, or scents the fragrance of nutmeg and cinnamon in the far-off golden Chersonese. Mrs. Sin doubtless lived anew the triumphs of earlier days in Buenos Ayres, when she had been La Belle Lola, the greatly beloved, and before she had met and married Sin Sin Wa. Gives much, but claims all, and he who would open the poppy-gates must close the door of ambition and bid farewell to manhood.
 
Sir Lucien stood looking at the woman, and although one pipe had affected him but slightly, his imagination momentarily ran riot and a pageant of his life swept before him, so that his jaw grew hard and grim and he clenched his hands convulsively. An unbroken stillness prevailed in the opium-house of Sin Sin Wa.
 
Recovering from his fit of abstraction, Pyne, casting a final keen glance at the sleeper, walked out of the room. He looked along the carpeted corridor in the direction of the cubicles, paused, and then opened the heavy door masking the recess behind the cupboard. Next opening the false back of the cupboard, he passed through to the lumber-room beyond, and partly closed the second door.
 
He descended the stair and went along the passage; but ere he reached the door of the room on the ground floor:
 
“Hello! hello! Sin Sin! Sin Sin Wa!” croaked the raven. “Number one p'lice chop, lo!” The note of a police whistle followed, rendered with uncanny fidelity.
 
Pyne entered the room. It presented the same aspect as when he had left it. The ship's lantern stood upon the table, and Sin Sin Wa sat upon the tea-chest, the great black bird perched on his shoulder. The fire in the stove had burned lower, and its downcast glow revealed less mercilessly the dirty condition of the floor. Otherwise no one, nothing, seemed to have been disturbed. Pyne leaned against the doorpost, taking out and lighting a cigarette. The eye of Sin Sin Wa glanced sideways at him.
 
“Well, Sin Sin,” said Sir Lucien, dropping a match and extinguishing it under his foot, “you see I am not smoking tonight.”
 
“No smokee,” murmured the Chinaman. “Velly good stuff.”
 
“Yes, the stuff is all right, Sin.”
 
“Number one proper,” crooned Sin Sin Wa, and relapsed into smiling silence.
 
“Number one p'lice,” croaked the raven sleepily. “Smartest—” He even attempted the castanets imitation, but was overcome by drowsiness.
 
For a while Sir Lucien stood watching the singular pair and smiling in his ironical fashion. The motive which had prompted him to leave the neighboring house and to seek the companionship of Sin Sin Wa was so obscure and belonged so peculiarly to the superdelicacies of chivalry, that already he was laughing at himself. But, nevertheless, in this house and not in its secret annex of a Hundred Raptures he designed to spend the night. Presently:
 
“Hon'lable p'lice patrol come 'long plenty soon,” murmured Sin Sin Wa.
 
“Indeed?” said Sir Lucien, glancing at his wristwatch. “The door is open above.”
 
Sin Sin Wa raised one yellow forefinger, without moving either hand from the knee upon which it rested, and shook it slightly to and fro.
 
“Allee lightee,” he murmured. “No bhobbery. Allee peaceful fellers.”
 
“Will they want to come in?”
 
“Wantchee dlink,” replied Sin Sin Wa.
 
“Oh, I see. If I go out into the passage it will be all right?”
 
“Allee lightee.”
 
Even as he softly crooned the words came a heavy squelch of rubbers upon the wet pavement outside, followed by a rapping on the door. Sin Sin Wa glanced aside at Sir Lucien, and the latter immediately withdrew, partly closing the door. The Chinaman shuffled across and admitted two constables. The raven, remaining perched upon his shoulder, shrieked, “Smartest leg in Buenos Ayres,” and, fully awakened, rattled invisible castanets.
 
The police strode into the stuffy little room without ceremony, a pair of burly fellows, fresh-complexioned, and genial as men are wont to be who have reached a welcome resting-place on a damp and cheerless night. They stood by the stove, warming their hands; and one of them stooped, took up the little poker, and stirred the embers to a brighter glow.
 
“Been havin' a pipe, Sin?” he asked, winking at his companion. “I can smell something like opium!”
 
“No smokee opium,” murmured Sin Sin Wa complacently. “Smokee Woodbine.”
 
“Ho, ho!” laughed the other constable. “I don't think.”
 
“You likee tly one piecee pipee one time?” inquired the Chinaman. “Gotchee fliend makee smokee.”
 
The man who had poked the fire slapped his companion on the back.
 
“Now's your chance, Jim!” he cried. “You always said you'd like to have a cut at it.”
 
“H'm!” muttered the other. “A 'double' o' that fifteen over-proof Jamaica of yours, Sin, would hit me in a tender spot tonight.”
 
“Lum?” murmured Sin Sin blandly. “No hate got.”
 
He resumed his seat on the tea-chest, and the raven muttered sleepily, “Sin Sin—Sin.”
 
“H'm!” repeated the constable.
 
He raised the skirt of his heavy top-coat, and from his trouser-pocket drew out a leather purse. The eye of Sin Sin Wa remained fixed upon a distant corner of the room. From the purse the constable took a shilling, ringing it loudly upon the table.
 
“Double rum, miss, please!” he said, facetiously. “There's no treason allowed nowada............
