It's been quite some time since I've read it, but I've found how few people know Robert W. Chambers to be rather shocking. You can see where Lovecraft got some of his ideas and the stories--both the Gothic and the Romantic--are quite entertaining.
I personally like The Yellow Sign where the weird tales are concerned, and I would perhaps say where the romantic tales are concerned, Rue Baree and Our Lady of the Fields are about equal. The latter two stories I love because the dialogue is great, and The Yellow Sign is just flat-out eerie.
Anybody else have a favorite or two?
