Sherlock Holmes in London: Observation, Deduction & Knowledge.

It happens in every city -- when we read fiction, it is often based in reality, and when it is tied to a specific place.

The places are real, even though the characters are fictional. People love to visit places described in books; it how I started my digital story. 

The Sherlock Holmes Museum is the most popular privately run museum in London. The address is 221B Baker Street is the world's most famous address, even though 221 Baker Street existed only in Conan Doyle's imagination.  Still, if you're planning to visit the museum, prepare to pay 6 pounds, climb a very narrow stairs to see for yourself how imagination, stories, & descriptions recreate a real atmosphere of Sherlock Holmes house.

 Observation, deduction and knowledge are main steps of Sherlock's Holmes problem solving method.  Still, no one can solved mystery as well as Sherlock Holmes did: discovering clues, deducting the cause, and finding solution.
