Alchemy Trail
Step into London's medieval past.
↑ Tower Hill Station
The game begins at Baker Street. From there, it's deduction all the way.
Solving crime is just a walk in the park.
Walk with Holmes through literary London. Collect clues, piece them together and deduce the solution. The story is fiction — but the setting is entirely real. From Baker Street through Marylebone, every corner holds another piece of the puzzle. Elementary? We'll see.
The puzzle begins with a stolen document and ends somewhere you won't expect. Along the way, you'll test your powers of observation against a story designed by writers who take Holmes seriously — not as a costume, but as a method. Every clue has a logical solution. Every detail matters. The trail covers real locations from the original Conan Doyle stories, and you'll leave knowing Baker Street considerably better than you did going in.
★★★★★"A brilliant afternoon — the clues are genuinely clever, not patronising. We were properly stumped at stage four."
★★★★★"As a Holmes obsessive, this was everything I hoped for. The locations are spot on and the mystery is first-rate."
