The fog plucked at me with ghostly fingers, cold as the hands of dead men, as I raced down the street. I had no plan, but one was forming in my mind, beginning to seethe in the stimulated cauldron that was my brain. I halted at the sight of a policeman pacing his beat, and beckoning him to me, scribbled a terse note on a piece of paper torn from a notebook and handed it to him.

"Get this to Scotland Yard; it's a matter of life and death and it has to do with the business of John Gordon."

At that name, a gloved hand came up in swift assent, but his assurance of haste died out behind me as I renewed my flight. The note stated briefly that Gordon was a prisoner at Soho 48 and advised an immediate raid in force—advised, nay, in Gordon's name, commanded it.

My reason for my actions was simple; I knew that the first noise of the raid sealed John Gordon's doom. Somehow I first must reach him and protect or free him before the police arrived.

The time seemed endless, but at last the grim gaunt outlines of the house that was Soho 48 rose up before me, a giant ghost in the fog. The hour grew late; few people dared the mists and the dampness as I came to a halt in the street before this forbidding building. No lights showed from the windows, either upstairs or down. It seemed deserted. But the lair of the scorpion often seems deserted until the silent death strikes suddenly.

Here I halted and a wild thought struck me. One way or another, the drama would be over by dawn. Tonight was the climax of my career, the ultimate top of life. Tonight I was the strongest link in the strange chain of events. Tomorrow it would not matter whether I lived or died. I drew the flask of elixir from my pocket and gazed at it. Enough for two more days if properly eked out. Two more days of life! Or—I needed stimulation as I never needed it before; the task in front of me was one no mere human could hope to accomplish. If I drank the entire remainder of the elixir, I had no idea as to the duration of its effect, but it would last the night through. And my legs were shaky; my mind had curious periods of utter vacuity; weakness of brain and body assailed me. I raised the flask and with one draft drained it.

For an instant I thought it was death. Never had I taken such an amount.

Sky and world reeled and I felt as if I would fly into a million vibrating fragments, like the bursting of a globe of brittle steel. Like fire, like hell-fire the elixir raced along my veins and I was a giant! monster! a superman!

Turning, I strode to the menacing, shadowy doorway. I had no plan; I felt the need of none. As a drunken man walks blithely into danger, I strode to the lair of the Scorpion, magnificently aware of my superiority, imperially confident of my stimulation and sure as the unchanging stars that the way would open before me.

Oh, there never was a superman like that who knocked commandingly on the door of Soho 48 that night in the rain and the fog!
