Finding clues, testing evidence, uncovering secrets—it’s all part of the game at this month’s mystery-themed First Friday!

Join us for a night of “whodunits” and solve a historical forensics murder mystery. We’ll gather clues around the museum in your detective’s notebook and test our answers against a panel of experts. Play matching games, tour a new rare book exhibition about the science of blood, and enjoy chills and thrills…if you dare!
