Dusk had drawn a grey mantle over the East-End streets when Miska, discharging the cab in which she had come from Victoria, hurried furtively along a narrow alley tending Thamesward. Unconsciously she crossed a certain line—a line invisible except upon a map of London which lay upon the table of the Assistant Commissioner in New Scotland Yard—the line forming the "red circle" of M. Gaston Max. And, crossing this line, she became the focus upon which four pairs of watchful eyes were directed.  
Arriving at the door of a mean house some little distance removed from that of Ah-Fang-Fu, Miska entered, for the door was open, and disappeared from the view of the four detectives who were watching the street. Her heart was beating rapidly. For she had thought, as she had stood up to leave the restaurant, that the fierce eyes of Chunda Lal had looked in through the glass panel of one of the doors.
 
This gloomy house seemed to swallow her up, and the men who watched wondered more and more what had become of the elegant figure, grotesque in such a setting, which had vanished into the narrow doorway—and which did not reappear. Even Inspector Kelly, who knew so much about Chinatown, did not know that the cellars of the three houses left and right of Ah-Fang-Fu's were connected by a series of doors planned and masked with Chinese cunning.
 
Half an hour after Miska had disappeared into the little house near the corner, the hidden door in the damp cellar below "The Pidgin House" opened and a bent old woman, a ragged, grey-haired and dirty figure, walked slowly up the rickety wooden stair and entered a bare room behind and below the shop and to the immediate left of the den of the opium-smoker. This room, which was windowless, was lighted by a tin paraffin lamp hung upon a nail in the dirty plaster wall. The floor presented a litter of straw, paper and broken packing-cases. Two steps led up to a second door, a square heavy door of great strength. The old woman, by means of a key which she carried, was about to open this door when it was opened from the other side.
 
Lowering his head as he came through, Chunda Lal descended. He wore European clothes and a white turban. Save for his ardent eyes and the handsome fanatical face of the man, he might have passed for a lascar. He turned and half closed the door. The woman shrank from him, but extending a lean brown hand he gripped her arm. His eyes glittered feverishly.
 
"So!" he said, "we are all leaving England? Five of the Chinese sail with the P. and O. boat to-night. Ali Khan goes to-morrow, and Rama Dass, with Miguel, and the Andaman. I meet them at Singapore. But you?"
 
The woman raised her finger to her lips, glancing fearfully towards the open door. But the Hindu, drawing her nearer, repeated with subdued fierceness:
 
"I ask it again—but you?"
 
"I do not know," muttered the woman, keeping her head lowered and moving in the direction of the steps.
 
But Chunda Lal intercepted her.
 
"Stop!" he said—"not yet are you going. There is something I have to speak to you."
 
"Ssh!" she whispered, half turning and pointing up toward the door.
 
"Those!" said the Hindu contemptuously—"the poor slaves of the black smoke! Ah! they are floating in their dream paradise; they have no ears to hear, no eyes to see!" He grasped her wrist again. "They contest for shadow smiles and dream kisses, but Chunda Lal have eyes to see and ears to hear. He dream, too but of lips more sweet than honey, of a voice like the Song of the Daood! Inshalla!"
 
Suddenly he clutched the grey hair of the bent old woman and with one angry jerk snatched it from her head—for it was a cunning wig. Disordered, hair gleaming like bronze waves in the dim lamplight was revealed and the great dark eyes of Miska looked out from the artificially haggard face—eyes wide open and fearful.
 
"Bend not that beautiful body so," whispered Chunda Lal, "that is straight and supple as the willow branch. O, Miska"—his voice trembled emotionally and he that had been but a moment since so fierce stood abashed before her—"for you I become as the meanest and the lowest; for you I die!"
 
Miska started back from him as a muffled outcry sounded in the room beyond the half-open door. Chunda Las started also, but almost immediately smiled—and his smile was tender as a woman's.
 
"It is the voice of the black smoke that speaks, Miska. We are alone.
Those are dead men speaking from their tombs."
 
"Ah-Fang-Fu is in the shop," whispered Miska.
 
"And there he remain."
 
"But what of … him!"
 
Miska pointed toward the eastern wall of the room in which they stood.
 
Chunda Lal clenched his hands convulsively and turned his eyes in the same direction.
 
"It is of him," he replied in a voice of suppressed vehemence, "it is of him I would speak." He bent close to Miska's ear. "In the creek, below the house, is lying the motor-boat. I go to-day to bring it down for him. He goes to-night to the other house up the river. To-morrow I am gone. Only you remaining."
 
"Yes, yes. He also leaves England to-morrow."
 
"And you?"
 
"I go with him," she whispered.
 
Chunda Lal glanced apprehensively toward the door. Then:
 
"Do not go with him!" he said, and sought to draw Miska into his arms.
"O, light of my eyes, do not go with him!"
 
Miska repulsed him, but not harshly.
 
"No, no, it is no good, Chunda Lal. I cannot hear you."
 
"You think"—the Hindu's voice was hoarse with emotion—"that he will trace you—and kill you?"
 
"Trace me!" exclaimed Miska with sudden scorn. "Is it necessary for him to trace me? Am I not already dead except for him! Would I be his servant, his lure, his slave for one little hour, for one short minute, if my life was my own!"
 
Beads of perspiration gleamed upon the brown forehead of the Hindu, and his eyes turned from the door to the eastern wall and back again to Miska. He was torn by conflicting desires, but suddenly came resolution.
 
"Listen, then." His voice was barely audible. "If I tell you that your life is your own—if I reveal to you a secret which I learned in the house of Abdul Rozan in Cairo——"
 
Miska watched him with eyes in which a new, a wild expression was dawning.
 
"If I te............
