The Fontana Book of Great Ghost Stories (1964): edited by Robert Aickman: Solid 'Best of' collection apart from the annual, numbered Fontana Ghost Stories paperbacks.
Edited by the great and idiosyncratic 'strange story' writer (and English Inland Waterway enthusiast) Robert Aickman, this collection contains many great stories, including Algernon Blackwood's "The Wendigo" and Walter de la Mare's "Seaton's Aunt" along with Aickman's own "The Trains." It includes one stinker, the twee and mostly unfunny funny ghost story "The Ghost Ship." Highly recommended.
In the Shadow of the Master: Classic Tales by Edgar Allan Poe (2009): edited by Michael Connelly: A tribute to Poe from the Mystery Writers of America, whose annual award(s) is named the Edgar, after Poe.
The early-20th-century illustrations by Harry Clarke are really nice. The stories are pretty much a 'Best of' Poe's greatest stories, along with poems "The Raven" and "The Bells" and an excerpt from Poe's great, truncated novel The Narrative of Arthur Gordon Pym. Also included are essays from members of the MWA on what Poe means (or doesn't mean) to them. As a Poe collection, you can certainly do worse. Highly recommended.
The Reddening (2019) by Adam L.G. Nevill: Gripping, grueling, visionary work of cosmic folk horror from the author of The Ritual and Last Days. Archaeological discoveries in modern-day Devon draw a grieving sister and a depressed Lifestyle reporter into an ancient mystery and an ancient horror.
Mysterious underground sounds, a long line of disappearances and unexpected suicides, and the run-down farm of a minor rock-folk star of the 1960's figure in the narrative. So, too, people high and low lacking all empathy.
The mysteries of the ancient cult and its supernatural progenitors are vividly imagined and described, as are the psychologies of protagonists and antagonists alike. While not for the squeamish, the violence is modulated and necessary to the depiction of the cult and to the larger questions about humanity's love for ultra-violence.
Nevill weaves social commentary into the horrible imaginings, with the worst instincts of humanity being linked to Brexit and austerity measures and the overall rise of xenophobia and fascism throughout the world. It's the sort of novel that justifies my recent blurby observation that Nevill's two clearest forerunners in British horror are James Herbert and Ramsey Campbell. Highly recommended.
