So, was August Derleth dim?
I've always assumed the answer was "no" -- after all, he was a correspondent of the quirkily erudite Lovecraft, who did not suffer fools gladly; the founder and manager of a successful small press, who got into print some authors of real talent who might otherwise have languished; and the author of many books on a wide variety of topics. Granted, a lot of what he wrote was pastiche, which takes a lot less talent than writing original works, but good pastiche takes not just panache but a good deal of knowledge about the original being imitated. But now I'm beginning to wonder.
Most people know him mainly through his "posthumous collaborations" with Lovecraft, which were in fact written entirely by Derleth under the pretext (i.e., deliberate deceit) that he was finishing a Lovecraft manuscript (a Lovecraft story sold for more than a Derleth story, which is why he often tried to pass his work off as someone else's). And while he's been duly credited for preserving Lovecraft's memory and keeping him in print*, it's universally agreed that he deliberately misrepresented Lovecraft's underlying philosophy and substituted his own beliefs instead. But what if he simply grossly misunderstood Lovecraft on a fundamental level?
I suppose what's shaken me is my just having finished THE CHRONICLES OF SOLAR PONS , a (posthumous) collection of Derleth's Sherlock Holmes pastiche, and it's made me realize that Derleth didn't know nearly as much about literature, particularly detective literature, as I'd assumed. I'd picked up a library discard of MEMOIRS OF SOLAR PONS  years ago at a library sale for a quarter and, more recently, MR. FAIRLIE'S FINAL JOURNEY , the only novel in the series, at the latest Seattle Antiquarian Book Fair. Both are amusing mainly in the shamelessness of their direct borrowings, which far exceeds that of his 'Cthulhu' stories -- as an analogy, if Derleth is to Lovecraft as Terry Brooks is to Tolkien, then Derleth is to Conan Doyle as Dennis McKiernan is to JRRT. But what's more surprising is that in this latest collection at least Derleth gets things wrong.
"Wrong" not in the general sense of misrepresenting the spirit of the stories, though that's there too (as when Pons shoots a woman dead in a fashion more suitable to a psychopath like Matt Helm than a consulting detective of the old school, or in the story in which Fu Manchu is the beneficent defender of wronged womanhood). Rather, wrong as in presenting Hercule Poirot as French ("The Adventure of the Orient Express", p. 58), or when a book collector displays some of his treasures, including a signed copy of EDWIN DROOD ("The Adventure of the Unique Dickensians", p. 233). There's nothing wrong in making mistakes -- we all slip up once in a while -- but to write an adventure intended to display your knowledge of Dickens and not get the Dickens parts right is dumbfounding.
So, I'm currently at a bit of a loss. Perhaps I'll be in a more charitable mood later, but right now I'm entertaining the thought that Derleth had energy and enthusiasm but not erudition, and it might be this that separates him from HPL more than anything else.
