This is one I have read before, and was glad to read again. It's Strete's most famous story, I believe, now collected in If All Else Fails. Strete's images and ideas are extroardinary, which is a good thing as his characters tend to cardboard, other than the mystical ones. This story is the best example, a completely inexplicable man, bleeding continuously at a rate no one could sustain. Very simply described and told, yet complete. The characters' reaction is revulsion, yet the way Strete describes him is not overly horrific. Mostly it's the simplicity, the lack of over-the-top adjectives and creepy tension. It's a man in an institution.
Read this for a thoughtful horror fix, it's a good surrealism example. 3 stars.
