JD, I have to disagree with you on The Squaw and The Judge's House. They're the opposite of you claimed they were. I've read those two several times before. Same with Dracula's Guest.
That's quite interesting. I can almost see it with "The Judge's House", as there are moments when it does achieve a certain tensity of atmosphere... but having very recently reread "The Squaw", I stand by my assessment. It's an horrific situation, no question, but to me it comes off as contrived rather than having any sort of genuine artistry, and the writing itself varies between being extremely flat and prosaic to overheated and overcolored... while maintaining at all times a certain hackneyed journalistic feel very much like the penny dreadfuls. Actually, I found a comic adaptation of it I read when young to be much more powerful as far as atmosphere, because of the fine use of chiaroscuro. But Stoker's actual writing style overall is often his weakest point, IMO...
Dracula being something of an exception. As for "Dracula's Guest"... as that was a chapter of the novel which was excerpted from earlier editions, it's not surprising that it has something of the same eeriness as the novel itself, and I think it's a pity it wasn't left where it belonged....
Lair of the White Worm, on the other hand -- again, a very good idea, but his often crude, almost always uneven prose simply robs it of most of its potential as it stands... the idea remains a powerful one, but the execution is, frankly, more than disappointing.
