The white serpents coiled past the pillars, brushed the low ceiling, moistly caressed the backs of their devotees and source, and then in turn coalesced to pour up the curving black hole of a narrow spiral stairway, the stone steps of which were worn almost to chutelike smoothness — a sinuously billowing white cylinder in which a redness lurked. And all the while the drums and cymbals did not falter for a single beat, nor did the Hell-light tenders cease to crank the wooden wheels on which shielded, red-burning candles were affixed, nor did the eyes of the Archpriest flicker once sideways in their wooden mask, nor did one mesmerized bent soul look up.

Along a misted alley overhead there was hurrying home to the thieves’ quarter a beggar girl, skinny-frail of limb and with eyes big as a lemur's peering fearfully from a tiny face of elfin beauty. She saw the white pillar, slug-flat now, pouring out between the bars of a window-slit level with the pavement, and although there were thick chilly tendrils of river-fog already following her, she knew that this was different.

She tried to run around the thing, but swift almost as a serpent striking, it whipped across to the opposite wall, barring her way. She ran back, but it outraced her and made a U, penning her against the unyielding wall. Then she only stood still and shook as the fog-serpent narrowed and grew denser and came wreathing around her. Its tip swayed like the head of a poisonous snake preparing to strike and then suddenly dipped toward her breast. She stopped shaking then and her head fell back and the pupils rolled up in her lemurlike eyes so that they showed only great whites, and she dropped to the pavement limp as a rag.
