No fictional character has been portrayed more often on stage and screen than Sherlock Holmes. Fans flock from all over the world to see the locations where he lived, worked and brought justice to Victorian London. The BBC’s Sherlock series starring Benedict Cumberbatch and Martin Freeman has only increased his popularity.

London is a "world class" city on many levels, and attracts visitors for a wide variety of reasons, and none more so than for its theatrical reputation, credentials and concentration of West End theatres, known as "Theatreland." Today there are well over sixty theatres both large and small located in a fairly tight geographical area.
