Watson Adventures’ Murder at the Museum of American History Scavenger Hunt

Someone, or some “thing,” has been bumping off National Museum of American History staffers involved in the recent discovery of a long-lost invention by Benjamin Franklin. This “infernal machine” has a murky past: Freemasons supposedly used it as part of a secret ritual. Are the deaths caused by the invention, or part of the fabled “Curse of the Freemasons”? Or is a serial killer on the loose? Your team of sleuths will have to crack a secret code and uncover the museum’s secrets to solve the mystery and stop the killings. Advance purchase is required.
