The book turned out to be mostly satisfying, as I recall; all the stories included are Campbell's (mostly) Lovecraftian tales. There are efforts from the '60s with the requisite "Noun preposition Place" ("The Church in High Street," "The Insects from Shaggai," "The Inhabitant of the Lake") and then later pieces from the '70s and '80s such as "The Face at Pine Dunes" (see? it's addicting), "The Tugging," and the masterful "The Voice of the Beach." In these we are treated to Campbell's penchant for intertwining intimate stories of drab workaday British life with his own style of cosmic horror. A few stories did leave me a little bewildered due to his sometimes well-known vague prose stylings. He also wrote a must-read intro about the incalculable influence Lovecraft had, and has, on him since he was 14 years old: "I read [Lovecraft's] book in a single malingering day off school; for a year or more I thought H.P. Lovecraft was not merely the greatest horror writer of all time, but was the greatest writer I had ever read."
But don't expect more octopoid gods with gibberish for names, strange batrachian races of semi-humans, or ancient tomes of unknown binding; what Campbell does in these dense, carefully-wrought stories is create an overwhelming mood of dis-ease and fetid decay, of perception widened and skewed just so, so that one suddenly and for only a moment becomes aware of that chitinous skittering of something like claws at the cosmic rim.
I dozed gratefully, for I felt more delirious, my head felt packed with grains of sand that gritted together; in fact the whole of me was made of sand. Of course it was true that I was was composed of particles, and I thought my delirium had found a metaphor for that. But the grains that floated through my vision were neither sand nor atoms. A member, dark and vague, was reaching for them. I struggled to awaken; I didn't want to distinguish its shape... for as the member sucked them into itself, engulfing them in a way that I refused to perceive, I saw that the grains were worlds and stars.
