Dr. Fu-Manchu was entering the room immediately beyond.
Snatching up the bunch of keys, I turned and ran, for in another instant my retreat would be cut off. As I burst once more into the darkened room I became aware that a door on the further side of it was open; and framed in the opening was the tall, high-shouldered figure of the Chinaman, still enveloped in his fur coat and wearing the grotesque cap. As I saw him, so he perceived me; and as I sprang to the window, he advanced.
I turned desperately and hurled the bunch of keys with all my force into the dimly-seen face…
Either because they possessed a chatoyant quality of their own (as I had often suspected), or by reason of the light reflected through the open window, the green eyes gleamed upon me vividly like those of a giant cat. One short guttural exclamation paid tribute to the accuracy of my aim; then I had the crossbar in my hand. I threw one leg across the sill, and dire as was my extremity, hesitated for an instant ere trusting myself to the flight…
A vise-like grip fastened upon my left ankle.
Hazily I became aware that the dark room was flooded with figures. The whole yellow gang were upon me—the entire murder-group composed of units recruited from the darkest place of the East!
I have never counted myself a man of resource, and have always envied Nayland Smith his possession of that quality, in him extraordinarily developed; but on this occasion the gods were kind to me, and I resorted to the only device, perhaps, which could have saved me. Without releasing my hold upon the crossbar, I clutched at the ledge with the fingers of both hands and swung back into the room my right leg, which was already across the sill. With all my strength I kicked out. My heel came in contact, in sickening contact, with a human head; beyond doubt that I had split the skull of the man who held me.
The grip upon my ankle was released automatically; and now consigning all my weight to the rope I slipped forward, as a diver, across the broad ledge and found myself sweeping through the night like a winged thing…
The line, as Karamaneh had assured me, was of well-judged length. Down I swept to within six or seven feet of the street level, then up, at ever decreasing speed, toward the vague oblong of the open window beyond.
I hope I have been successful, in some measure, in portraying the varied emotions which it was my lot to experience that night, and it may well seem that nothing more exquisite could remain for me. Yet it was written otherwise; for as I swept up to my goal, describing the inevitable arc which I had no power to check, I saw that one awaited me.
Crouching forward half out of the open window was a Burmese dacoit, a cross-eyed, leering being whom I well remembered to have encountered two years before in my dealings with Dr. Fu-Manchu. One bare, sinewy arm held rigidly at right angles before his breast, he clutched a long curved knife and waited—waited—for the critical moment when my throat should be at his mercy!
I have said that a strange coolness had come to my aid; even now it did not fail me, and so incalculably rapid are the workings of the human mind that I remember complimenting myself upon an achievement which Smith himself could not have bettered, and this in the immeasurable interval which intervened between the commencement of my upward swing and my arrival on a level with the window.
I threw my body back and thrust my feet forward. As my legs went through the opening, an acute pain in one calf told me that I was not to escape scatheless from the night's melee. But the dacoit went rolling over in the darkness of the room, as helpless in face of that ramrod stroke as the veriest infant…
Back I swept upon my trapeze, a sight to have induced any passing citizen to question his sanity. With might and main I sought to check the swing of the pendulum, for if I should come within reach of the window behind I doubted not that other knives awaited me. It was no difficult feat, and I succeeded in checking my flight. Swinging there above Museum Street I could even appreciate, so lucid was my mind, the ludicrous element of the situation.
I dropped. My wounded leg almost failed me; and greatly shaken, but with no other serious damage, I picked myself up from the dust of the roadway. It was a mockery of Fate that the problem which Nayland Smith had set me to solve, should have been solved thus; for I could not doubt that by means of the branch of a tall tree or some other suitable object situated opposite to Smith's house in Rangoon, Karamaneh had made her escape as tonight I had made mine.
Apart from the acute pain in my calf I knew that the dacoit's knife had bitten deeply, by reason of the fact that a warm liquid was trickling down into my boot. Like any drunkard I stood there in the middle of the road looking up at the vacant window where the dacoit had been, and up at the window above the shop of J. Salaman where I knew Fu-Manchu to be. But for some reason the latter window had been closed or almost closed, and as I stood there this reason became apparent to me.
The sound of running footsteps came from the direction of New Oxford Street. I turned—to see two policemen bearing down upon me!
This was a time for quick decisions and prompt action. I weighed all the circumstances in the balance, and made the last vital choice of the night; I turned and ran toward the British Museum as though the worst of Fu-Manchu's creatures, and not my allies the police, were at my heels!
No one else was in sight, but, as I whirled into the Square, the red lamp of a slowly retreating taxi became visible some hundred yards to the left. My leg was paining me greatly, but the nature of the wound did not interfere with my progress; therefore I continued my headlong career, and ere the police had reached the end of Museum Street I had my hand upon the door handle of the cab—for, the Fates being persistently kind to me, the vehicle was for hire.
"Dr. Cleeve's, Harley Street!" I shouted at the man. "Drive like hell! It's an urgent case."
I leaped into the cab.
Within five seconds from the time that I slammed the door and dropped back panting upon the cushions, we were speeding westward toward the house of the famous pathologist, thereby throwing the police hopelessly off the track.
Faintly to my ears came the purr of a police whistle. The taxi-man evidently did not hear the significant sound. Merciful Providence had rung down the curtain; for to-night my role in the yellow drama was finished.
Chapter 21 CRAGMIRE TOWER
Less than two hours later, Inspector Weymouth and a party of men from Scotland Yard raided the house in Museum Street. They found the stock of J. Salaman practically intact, and, in the strangely appointed rooms above, every evidence of a hasty outgoing. But of the instruments, drugs and other laboratory paraphernalia not one item remained. I would gladly have given my income for a year, to have gained possession of the books, alone; for, beyond all shadow of doubt, I knew them to contain formula calculated to revolutionize the science of medicine.
Exhausted, physically and mentally, and with my mind a whispering-gallery of conjectures (it were needless for me to mention whom respecting) I turned in, gratefully, having patched up the slight wound in my calf.
I seemed scarcely to have closed my eyes, when Nayland Smith was shaking me into wakefulness.
"You are probably tired out," he said; "but your crazy expedition of last night entitles you to no sympathy. Read this; there is a train in an hour. We will reserve a compartment and you can resume your interrupted slumbers in a corner seat."
As I struggled upright in bed, rubbing my eyes sleepily, Smith handed me the Daily Telegraph, pointing to the following paragraph upon the literary page:
