    In 1885, a young doctor named Arthur Conan Doyle opened offices in London.

    He wanted to be a successful doctor, but for some reasons he never found enough patients.

To pass the time, he began to write stories and send them to the newspapers.

    Conan Doyle's stories were about a clever detective, Sherlock Holmes.Conan Doyle wrote

that Sherlock Holmes lived in Baker Street in London, and people with problems came to

Sherlock Holmes with their problems, too.He was able to solve mysteries (疑难案件) that the

cleverest policemen in England were unable to figure out (解决)．

    Sometimes Sherlock Holmes could solve a mystery without leaving his chair.He listened

carefully to the information his client (委托人) gave and figured out the answer.At other times he

spent days or weeks looking for clues (线索)．Sherlock Holmes travelled to different cities and

countries to solve the mysteries.Sometimes he wore_disguises,_pretending to be an old man, or a

sailor.Holmes did anything to find out the answer to the mysteries he was working on.

    Sherlock Holmes is the most famous detective in English literature (文学),but many people don't

understand that he is a fictional (小说的) character, not a real person.The English post offices report

that people still send mail to Sherlock Holmes in Baker Street.Even he gets more than 2,000 letters

every year.
