Elementary?  Maybe for Sherlock Holmes, but how will you fare when you try to solve a captivating, original murder mystery in the tradition of the master detective?  Come inside and find out!

More than a century ago, in 1886, a struggling young doctor named Arthur Conan Doyle wrote a story about a brilliant and enigmatic detective. The 26-year-old author would probably have been amazed to know that Sherlock Holmes would become one of the most inspiring and influential characters of all time.

The legendary sleuth of Baker Street, a chemistry and forensics expert ahead of his time, used seemingly trivial observations of evidence that others missed to solve the most baffling mysteries imaginable. His practices and techniques changed the way police work was conducted in the real world, lighting the way to the modern forensics of today.

The International Exhibition of Sherlock Holmes brings this world to life as never before as you step into Conan Doyle’s Victorian London and work side-by-side with his legendary detective.  You will become Holmes’ eyes and ears as he tackles a baffling new case in a world steeped in innovation and experimentation. Along the way you’ll see a dazzling array of original manuscripts, publications, period artifacts, film and television props and costumes.  You’ll learn to use investigative tools and techniques from Holmes himself, and test yourself with exciting, interactive crime-solving opportunities.

Hurry along!  The game’s afoot!
