again—fighting the invader. "Almost it eluded me then, Effulgent Lord. Link with this lowly one!" "Impossible! Do you forget all my teachings? Cling, though you expend the last filament of your life-force!" Free from all distraction, at a level where comprehension and retention are instantaneous and total, my monitoring basic personality fraction followed the skillful Gool mind as it engraved its commands deep in my subconscious. Then the touch withdrew, erasing the scars of its passage, to leave me unaware of its tampering—at a conscious level. Watching the Gool mind, I learned. The insinuating probe—a concept regarding which psychodynamicists had theorized—was no more than a pattern in emptiness.... But a pattern which I could duplicate, now that I had seen what had been done to me. Hesitantly, I felt for the immaterial fabric of the continuum, warping and manipulating it, copying the Gool probe. Like planes of paper-thin crystal, the polyfinite aspects of reality shifted into focus, aligning themselves. Abruptly, a channel lay open. As easily as I would stretch out my hand to pluck a moth from a night-flower, I reached across the unimaginable void—and sensed a pit blacker than the bottom floor of hell, and a glistening dark shape. There was a soundless shriek. "Effulgence! It reached out—touched me!" Using the technique I had grasped from the Gool itself, I struck, stifling the outcry, invaded the fetid blackness and grappled the obscene gelatinous immensity of the Gool spy as it spasmed in a frenzy of xenophobia—a ton of liver writhing at the bottom of a dark well. I clamped down control. The Gool mind folded in on itself, gibbering. Not pausing to rest, I followed up, probed along my channel of contact, tracing patterns, scanning the flaccid Gool mind....

The Gool clustered at its rim, feeding, each monstrous shape heaving against its neighbors for a more favorable position. I probed farther, saw the great cables of living nervous tissue that linked each eating organ with the brain-mass far
