The hound of the Baskervilles is a story that combines the realms of the logical Darwinian sciences and the supernatural. There are many clear and apparent examples of these two topics throughout the story and they play a prevalent role in the theme of the book. .
One example of a supernatural idea in this story is the whole legend of "The Hound". This can be clearly seen on p.6 when out of an old manuscript it is read "a foul thing, a great black beast, larger than any other beast with great blazing eyes and a jaw dripping with blood". This quote shows us the fear the common man had for this supernatural beast and conveys a sense of bewilderment and confusion regarding its origin.
Another example of a supernatural event would be on p.44 when Dr. Watson and Sir Henry Baskervill are both awakened in the middle of the night by the sound of a woman crying. "It was the sobbing of a woman, the muffled strangling gasp of one who is torn by uncontrollable sorrow" p. 44 was Dr. Watson's account of the incident. What makes this even qualify as supernatural is that after Dr. Watson goes looking for the woman he finds that the only female sleeping in the house is Mrs. Stapleton who claims to have not been crying and eludes to the possibility of s supernatural explanation of the sounds. .
My third, and final example of a supernatural occurrence in the story would be when Dr. Watson and Mr. Stapleton are walking through the Moore and hear as Watson describes "A low moan, incredibly sad swept over the Moore" p. 49. When Stapleton offers the explanation "The peasants say it is the Hound of the Baskervilles calling for it's prey" p. 50 we are tricked into believing that the roar that was heard by Dr. Watson was that of the supernatural beast known as "The Hound". .
Darwinian logic also plays a grand role in this story. Mostly through the great detective Sherlock Holmes and his feats of defeating the supernatural and other forms of mystery with a logical explanation.
