The C.I.D. men having departed, the remaining pair saluted again.
"Well, you're on special duty to-night. You've been prompt, but don't stick your chests out so much. Do you know of a back way to Shen-Yan's?"
The men looked at one another, and both shook their heads.
"There's an empty shop nearly opposite, sir," replied one of them. "I know a broken window at the back where we could climb in. Then we could get through to the front and watch from there."
"Good!" cried the Inspector. "See you are not spotted, though; and if you hear the whistle, don't mind doing a bit of damage, but be inside Shen-Yan's like lightning. Otherwise, wait for orders."
Inspector Ryman came in, glancing at the clock.
"Launch is waiting," he said.
"Right," replied Smith thoughtfully. "I am half afraid, though, that the recent alarms may have scared our quarry-your man, Mason, and then Cadby. Against which we have that, so far as he is likely to know, there has been no clew pointing to this opium den. Remember, he thinks Cadby's notes are destroyed."
"The whole business is an utter mystery to me," confessed Ryman. "I'm told that there's some dangerous Chinese devil hiding somewhere in London, and that you expect to find him at Shen-Yan's. Supposing he uses that place, which is possible, how do you know he's there to-night?"
"I don't," said Smith; "but it is the first clew we have had pointing to one of his haunts, and time means precious lives where Dr. Fu-Manchu is concerned."
"Who is he, sir, exactly, this Dr. Fu-Manchu?"
"I have only the vaguest idea, Inspector; but he is no ordinary criminal. He is the greatest genius which the powers of evil have put on earth for centuries. He has the backing of a political group whose wealth is enormous, and his mission in Europe is to PAVE THE WAY! Do you follow me? He is the advance-agent of a movement so epoch-making that not one Britisher, and not one American, in fifty thousand has ever dreamed of it."
Ryman stared, but made no reply, and we went out, passing down to the breakwater and boarding the waiting launch. With her crew of three, the party numbered seven that swung out into the Pool, and, clearing the pier, drew in again and hugged the murky shore.
The night had been clear enough hitherto, but now came scudding rainbanks to curtain the crescent moon, and anon to unveil her again and show the muddy swirls about us. The view was not extensive from the launch. Sometimes a deepening of the near shadows would tell of a moored barge, or lights high above our heads mark the deck of a large vessel. In the floods of moonlight gaunt shapes towered above; in the ensuing darkness only the oily glitter of the tide occupied the foreground of the night-piece.
The Surrey shore was a broken wall of blackness, patched with lights about which moved hazy suggestions of human activity. The bank we were following offered a prospect even more gloomy-a dense, dark mass, amid which, sometimes, mysterious half-tones told of a dock gate, or sudden high lights leapt flaring to the eye.
Then, out of the mystery ahead, a green light grew and crept down upon us. A giant shape loomed up, and frowned crushingly upon the little craft. A blaze of light, the jangle of a bell, and it was past. We were dancing in the wash of one of the Scotch steamers, and the murk had fallen again.
Discords of remote activity rose above the more intimate throbbing of our screw, and we seemed a pigmy company floating past the workshops of Brobdingnagian toilers. The chill of the near water communicated itself to me, and I felt the protection of my shabby garments inadequate against it.
Far over on the Surrey shore a blue light-vaporous, mysterious-flicked translucent tongues against the night's curtain. It was a weird, elusive flame, leaping, wavering, magically changing from blue to a yellowed violet, rising, falling.
"Only a gasworks," came Smith's voice, and I knew that he, too, had been watching those elfin fires. "But it always reminds me of a Mexican teocalli, and the altar of sacrifice."
The simile was apt, but gruesome. I thought of Dr. Fu-Manchu and the severed fingers, and could not repress a shudder.
"On your left, past the wooden pier! Not where the lamp is-beyond that; next to the dark, square building-Shen-Yan's."
It was Inspector Ryman speaking.
"Drop us somewhere handy, then," replied Smith, "and lie close in, with your ears wide open. We may have to run for it, so don't go far away."
From the tone of his voice I knew that the night mystery of the Thames had claimed at least one other victim.
"Dead slow," came Ryman's order. "We'll put in to the Stone Stairs."
Chapter 6
A seemingly drunken voice was droning from a neighboring alleyway as Smith lurched in hulking fashion to the door of a little shop above which, crudely painted, were the words:
SHEN-YAN, Barber
I shuffled along behind him, and had time to note the box of studs, German shaving tackle and rolls of twist which lay untidily in the window ere Smith kicked the door open, clattered down three wooden steps, and pulled himself up with a jerk, seizing my arm for support.
We stood in a bare and very dirty room, which could only claim kinship with a civilized shaving-saloon by virtue of the grimy towel thrown across the back of the solitary chair. A Yiddish theatrical bill of some kind, illustrated, adorned one of the walls, and another bill, in what may have been Chinese, completed the decorations. From behind a curtain heavily brocaded with filth a little Chinaman appeared, dressed in a loose smock, black trousers and thick-soled slippers, and, advancing, shook his head vigorously.
"No shavee-no shavee," he chattered, simian fashion, squinting from one to the other of us with his twinkling eyes. "Too late! Shuttee shop!"
"Don't you come none of it wi' me!" roared Smith, in a voice of amazing gruffness, and shook an artificially dirtied fist under the Chinaman's nose. "Get inside and gimme an' my mate a couple o' pipes. Smokee pipe, you yellow scum-savvy?"
My friend bent forward and glared into the other's eyes with a vindictiveness that amazed me, unfamiliar as I was with this form of gentle persuasion.
"Kop 'old o' that," he said, and thrust a coin into the Chinaman's yellow paw. "Keep me waitin' an' I'll pull the dam' shop down, Charlie. You can lay to it."
"No hab got pipee-" began the other.
Smith raised his fist, and Yan capitulated.
"Allee lightee," he said. "Full up-no loom. You come see."
He dived behind the dirty curtain, Smith and I following, and ran up a dark stair. The next moment I found myself in an atmosphere which was literally poisonous. It was all but unbreathable, being loaded with opium fumes. Never before had I experienced anything like it. Every breath was an effort. A tin oil-lamp on a box in the middle of the floor dimly illuminated the horrible place, about the walls of which ten or twelve bunks were ranged and all of them occupied. Most of the occupants were lying motionless, but one or two were squatting in their bunks noisily sucking at the little metal pipes. These had not yet attained to the opium-smoker's Nirvana.
"No loom-samee tella you," said Shen-Yan, complacently testing Smith's shilling with his yellow, decayed teeth.
Smith walked to a corner and dropped cross-legged, on the floor, pulling me down with him.
"Two pipe quick," he said. "Plenty room. Two piecee pipe-or plenty heap trouble."
A dreary voice from one of the bunks came:
"Give 'im a pipe, Charlie, curse yer! an' stop 'is palaver."
Yan performed a curious little shrug, rather of the back than of the shoulders, and shuffled to the box which bore the smoky lamp. Holding a needle in the flame, he dipped it, when red-hot, into an old cocoa tin, and withdrew it with a bead of opium adhering to the end. Slowly roasting this over the lamp, he dropped it into the bowl of the metal pipe which he held ready, where it burned with a spirituous blue flame.
