Have read all of Doyle's Sherlock Holmes and probably others as well, just never bothered to put them in to amazon or goodreads, so dates wrong. Some KU some paperback some hardback some collections.
Twin works - The Adventure of the Speckled Band and The Hound of Baskerville explicates, science-wise, wherefore Sir Arthur Conan Doyle a spiritual arden became his twilight years.
Way those double mysteries merge twi an exotic com romantic context, that thru them is twice its solution solved scientifically, yet its setting found in the linking context above. For what could source and or a-force a-science (figuratively) funneling thru to solution, but those outer limits beyond, connecting superbly unknowably, still scientifically yet mysteriously - those twin works. .
A great bedtime book full of rollicking adventure stories, occasionally hilariously overwrought but fun nonetheless.
The Sherlock Holmes stories are so perfect that it's jarring to read his other stuff, which is often juvenile, derivative or sloppy by comparison. Draws directly from Poe, Stevenson, etc. However, the entertainment value is undeniable, and it's hard not to love some of these tales, which cover a wide swath of contemporary genres.
