Seabury Quinn was Weird Tales' most popular author. It can be argued that a lot of what he wrote was hackwork, but he could do quality in a pinch. One example is his novella, Roads, which saw print in the January 1938 Weird Tales (which actually went on sale in December 1937). I had low expectations when I read it, but I have to say this is one of the better Christmas stories I've read. It is definitely the best "Sword & Sorcery Christmas" tale I've ever read. Quinn seems to be channeling/paying homage to REH, who had been dead little over a year
It's considered a minor classic amongst WT aficionados and was the first illustrated book Arkham House ever published. If you can find it, check it out this Yuletide season.
