In Sherlock Holmes: The Red-Headed League by Sir Arthur Conan Doyle, our favourite detectives Sherlock Holmes and Dr. Watson take on a red headed client.
Mr. Wilson answered a newspaper advertisement for a job which seems to perfect to be true. All he has to do is go to a certain office for 4 hours a day in the afternoon and copy out the encyclopedia. The hours also happen to work out so perfectly with his evening home business that he does not even have to give that up. Perhaps the best of the deal is that his only qualification is that he has flaming red hair.
Sherlock Holmes: The Red-Headed League is another example of where you don’t try to solve the mystery itself but you try to decipher Sherlock Holme’s thought process in solving the mystery. Why does he bang his cane on the sidewalk before entering Mr. Wilson’s home?
