Sherlock Holmes is a fictional character of the late nineteenth and early twentieth centuries who first appeared in publication in 1887. He is the creation of Scottish author and physician Sir Arthur Conan Doyle. The Holmes stories are narrated by Holmes' friend and roommate Dr. John Watson.
A brilliant London-based "consulting detective", Holmes is famous for his intellectual prowess and is renowned for his skillful use of astute observation, deductive reasoning and forensic skills to solve difficult cases.
Holmes is famous for using small details, such as mud or water stains, to piece together the solution to a crime. He can use the same method to figure out someone's occupation. When he first met Watson, he was able to tell with a glance and a handshake that he was an army surgeon and had been to Afghanistan. He was also quite physically fit, skilled at boxing, fencing, and baritsu.
Although a fictional character, Shinichi Kudo looks up to him as the world's greatest detective. Shinichi admires his deductive skills, physical abilities, and even his love for the violin. It was to be more like Holmes that Shinichi played soccer and picked up the violin.
- In the Roller Coaster Murder Case Shinichi tells Ran about Holmes' deduction about Watson when they first met and proceeds to demonstrate the process by grabbing the hand of the girl waiting in line in front of him for the Mystery Coaster, deducing that she's a gymnast. Ran is surprised until Shinichi explains that the calluses on her hand are from performing on the uneven bars and that he had seen odd bruising above the girl's legs when the wind lifted her skirt earlier.
- In the Company President's Daughter Kidnapping Case a shrunken Shinichi uses Holmes' method of deduction (including recognizing mud stains) to prove to Agasa that he really is Shinichi. The main clue in the episode was that the family's dogs did not bark, as in "Silver Blaze" with its "curious incident of the dog in the night-time."
- In the Holmes Freak Murder Case there are several allusions to the Holmes stories. "Mycroft" is the name of Sherlock's older brother, the characters complete a test that only true Holmes fans would be able to answer, and the murderer's motive was due to one of the victims sullying the character of Irene Adler.
- In Chinatown Deja Vu in the Rain the name of the Chinese restaurant which Conan, Ran and Kogoro visits literally translates as "Conan Doyle Tower".
- In The Convenience Store Trap Ran remembers a quote from Holmes that Shinichi told her: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." Using this quote to help her, Ran deduces who has been stealing items from the convenience store.
- In Holmes' Revelation the bomber used titles and quotes from Holmes' stories to give clues as to where his next bombing would take place.
- In The Phantom of Baker Street, the setting is a virtual reality of Holmes' London with many references to characters, situations, and quotes.
