What is the author's style in The Adventure of the Speckled Band by Arthur Conan Doyle?

The language in "The Adventure of the Speckled Band" is lurid and colorful. Conan Doyle does his best to paint vivid, often eerie, and sometimes gruesome images in the reader's mind. His description of Dr. Grimesby Roylott's death cry goes on for an entire paragraph and manages to convey the horrific nature of the death itself, which is never described in the narrative. Conan Doyle's audience when he wrote stories for The Strand was middle class British adventure story enthusiasts.
