Footprints, splatter patterns and magnifying glasses: Journey into the mind of the world’s most iconic detective and be transported to Sherlock Holmes’ London from the more convenient locale of St. Paul. The highly anticipated and visually stunning exhibition opens Oct. 20 at the Minnesota History Center. Visitors will unlock the storied sleuth’s revolutionary investigative secrets through the interactive exhibit that combines history, science and culture to reveal the historic underpinnings of author Sir Arthur Conan Doyle’s rich and vibrant stories. Just as historians study history, visitors will follow clues, examine evidence and use powers of observation, but this time to solve a mystery in Sherlock’s world filled with innovation and experimentation. “I can’t think of a more fun or engaging way to learn about the historical process,” said Kent Whitworth, director and CEO of the Minnesota Historical Society.” For more information, visit minnesotahistorycenter.org, call 651-259-3000 or 1-800-657-3773.
