歇洛克·福尔摩斯（Sherlock Holmes）是一个虚构的侦探人物，是由19世纪末的英国侦探小说家阿瑟·柯南·道尔所塑造的一个非常聪明的侦探形象。福尔摩斯自己称自己是一名“咨询侦探”，也就是说当其他私人或官方侦探遇到困难时常常向他求救。故事透露福尔摩斯经常能够足不出户就可以解决很多疑难问题，但是大部分故事都集中讲述一些比较困难、需要福尔摩斯出门调查的案子。福尔摩斯善于通过观察与演绎法来解决问题。柯南·道尔是从自己就读的爱丁堡大学一名善于观察的老师的身上获得灵感，创造了福尔摩斯这一人物的。

Sherlock Holmes was transformed when he was hot upon such a scent as this. Men who had only known the quiet thinker and logician of Baker Street would have failed to recognize him. His face flushed and darkened. His brows were drawn into two hard black lines, while his eyes shone out from beneath them with a steely glitter.

Set against the foggy, mysterious backdrops of London and the English countryside, these are the first twelve stories ever published to feature the infamous Detective Sherlock Holmes and his side kick Doctor Watson.

They first appeared as stories in the Strand Magazine and feature some of his most famous and enjoyable cases, including 'A Scandal in Bohemia','The Adventure of the Blue Carbuncle' and 'The Red-headed League'.
