"All right. I give him one little kiss if he good boy!"

Tossing the tray in the air she caught it, rested its edge upon her hip, turned, and walked away down the room, puffing her cigarette.

"Listen," I said, bending across the table, "it was Zarmi who drove the cab that came for Nayland Smith to-day!"

"My God!" whispered Fletcher, "then it was nothing less than the hand of Providence that brought us here to-night. Yes! I know how you feel, Doctor!—but we must play our cards as they're dealt to us. We must wait—wait."

Out from the den of the opium-smokers came Zarmi, one hand resting upon her hip and the other uplifted, a smoldering yellow cigarette held between the first and second fingers. With a movement of her eyes she summoned us to join her, then turned and disappeared again through the low doorway.

The time for action was arrived—we were to see behind the scenes of the Joy-Shop! Our chance to revenge poor Smith even if we could not save him. I became conscious of an inward and suppressed excitement; surreptitiously I felt the hilt of the Browning pistol in my pocket. The shadow of the dead Fu-Manchu seemed to be upon me. God! how I loathed and feared that memory!

"We can make no plans," I whispered to Fletcher, as together we rose from the table; "we must be guided by circumstance."

In order to enter the little room laden with those sickly opium fumes we had to lower our heads. Two steps led down into the place, which was so dark that I hesitated, momentarily, peering about me.

Apparently some four of five persons squatted and lay in the darkness about me. Some were couched upon rough wooden shelves ranged around the walls, others sprawled upon the floor, in the center whereof, upon a small tea-chest, stood a smoky brass lamp. The room and its occupants alike were indeterminate, sketchy; its deadly atmosphere seemed to be suffocating me. A sort of choking sound came from one of the bunks; a vague, obscene murmuring filled the whole place revoltingly.

Zarmi stood at the further end, her lithe figure silhouetted against the vague light coming through an open doorway. I saw her raise her hand, beckoning to us.
