Many of us are cautious around dogs. However friendly they seem their energy and open panting jaws seem to summon some primitive instinct within us to be aware.
Once we advance to wolves those fears become rather more persuasive. Their wild and seemingly vicious, determined natures can induce panic in even the most foolhardy of us. Nature admires winners.
From there it is but a short step to the supernatural evil of Werewolves. Now fear is definitely the thing we feel pulsing through our veins summoning a flight response. But no matter what our hopes are werewolves, whether real or in the imaginations of this cast of chilling unrepentant authors, stroke knowing chords of terror into every sentence, as the pages turn our uneasiness begins to escalate. Terror begins to track our every step.
With such literary craftsmen as Saki, Hugh Walpole, Ambrose Bierce, Rudyard Kipling, Arthur Conan Doyle and others, that feeling happens time and time again.
