Arthur Conan Doyle was a Scottish writer and physician. In addition to the series of stories chronicling the activities of Sherlock Holmes and his friend Dr John Watson for which he is well-known, Doyle wrote on a wide range of topics, both fictional and non-fictional. Though Sir Arthur Conan Doyle is best known for his detective stories, he also wrote other short stories that are masterpieces of mystery and suspense. In some of the stories, a supressed uneasiness gradually builds up and evolves into sheer terror; in others, the story line unexpectedly changes and comes to an unlikely conclusion. In a mystery story "The Beetle-Hunter", a beginning doctor is employed by a British gentleman because of his strength, his medical degree, and his extreme knowledge of beetles.
