When I first read THE TERROR & OTHER TALES, I was under the impression from ST Joshi's introduction that he thought Arthur Machen's remaining works (the ones printed in this volume) were of poor quality. I spent the rest of the book determined to prove him wrong. Although I like Joshi as an editor (much better than Robert Price and his higher-criticism hangups), I think that academics sometimes become too focused on purity of form and lose sight of otherwise good writing. I personally like all of Arthur Machen's writing, both the cosmic horror and the everyday gone wrong. I was pleased to see, however, than when I reread the introduction I found that Joshi now agreed with me :)
Chaosium has previously produced 2 novels of Arthur Machen's fiction: THE THREE IMPOSTERS AND OTHER STORIES (which primarily contains "The Great God Pan" and the title story "The Three Imposters", which is actually a series of short stories) and THE WHITE PEOPLE AND OTHER STORIES (which contains "The White People" which heavily influenced HPL, "Ornaments in Jade", and "A Fragment of Life"). THE TERROR is the third (and presumably last) of the Arthur Machen line; I would call it a grab bag of anything remaining of Machen's work that is fit to print.
Machen's story "The Terror" is the title piece for this collection, and oddly it was the story I liked the least. It's about the animal kingdom turning on humanity during WW I, but the government is doing a coverup. Frankly it is somewhat slow and dry, and Machen seemed to be making a point rather than telling a story. Interestingly, at the end of "The Terror", the investigators find a farmhouse where some people took refuge from the "Terror" and read their diary - I was struck by the similarity to zombie movies (!) of all things, and I now wonder if George Romero had this story in mind when scripting "Night of the Living Dead"? Stranger things have happened...
The rest of the collected stories seem to me to be quieter, more prosaic stories where something has gone weird and it may be beyond the power of anyone to fix. Sometimes Machen will insert himself into the story as an ordinary journalist, a man interested in the story but with little power to affect the outcome. In style and substance, the remainder reminds me of MR James, which is high praise indeed.
Some of the better stories here are "The Lost Club" (which is distinctly eerie in finding the secret group of wealthy and famous, where at each gathering one member disappears), "The Dover Road" (which is sort of a ghost story but involves something more like spiritualism), and "Change" (where the children encounter something like "the White People" of Machen's earlier work). Some, like "The Islington Mystery", "Out of the Picture", and "The Bright Boy" are about criminals and their misdeeds, but there is some supernatural element that twists the whole thing into some horrible aspect. I can defintiely see hints and phrases that HPL would pick up on and use in some of his work; also, the two were writing at the same time towards the end of Machen's life, so perhaps there was a common style of the times for them to use.
I can highly recommend this anthology as being worth collecting.
