Not all of the stories were 5 ⭐, but those that were were *so* 5⭐ that I've no hesitation in giving a maximum rating to the collection as a whole.
Blackwood's ability to evoke a liminal sense of something other impinging on the ordinary is wonderful, and this overlay of one reality with another is probably most fully developed in the classic "Ancient Sorceries", but is evident throughout in degrees. ⬇️
