As far as I am concerned, nothing is more admirable and surprising in the hero Sherlock Homes than his profound knowledge which has certainly assisted him a lot when he was studying the case. Take the bicycle tyres for instance, Holmes actually is capable of recognizing 42 different varieties of bicycle tyres. What’s more, according to his other stories, Holmes has studied different kinds of newspapers, cigarettes, people’s footprints and other special things as well. Therefore, he seems to have the mastery of anything relevant to the cases he deals with. Except for his illimitable knowledge, Holmes also specializes in arranging the facts in order and then finding the fact leading him to a great discovery or even the truth itself. From his speaking “Every mystery has an answer”, we can readily shape the impression of a man with great intelligence and inflexible will. In this case, after getting rid of unrelated facts, Sherlock Homes eventually grasped the clue and discovered the amazing fact.

    Needless to say, as a world-renowned masterpiece, Sherlock Holmes and the Duke’s Son has attracted and is still charming numerous readers from all corners of the world and people from all walks of life. The “Holmes series” has already set up a standard against which all the following detective fictions are measured. Sherlock Holmes, beyond all doubt, has become a name firmly rooted in people’s memories. Although Dr. Watson’s closing The Case Book of Sherlock Holmes in 1927 was a great pity to the readers, the discontinuance of the entire “Holmes series” may have actually added to the legendary stature of Sherlock Holmes.
