Today, time, the Blitz, and urban redevelopment have taken their toll, but much of what Sherlock "saw" is still there. Conan Doyle was unusually precise in his London addresses and locations, only occasionally disguising a site. To help find Sherlock's London, Thomas B. Wheeler, a London expert and owner of London Secrets, has identified an "astonishing" 200 sites, and cross-referenced them by adventure, and by the closest modern underground station.
"Finding Sherlock's London" is a London guidebook for Sherlock Holmes enthusiasts. To get the most out of it, reread your favorite Sherlock Holmes adventures before leaving home, and buy a pocket magnifying glass. After you arrive in London, purchase a modern street guide (for which you will need the magnifying glass), and a TravelCard for unlimited travel on London's Underground. Then, enjoy--the game is afoot!
