Sleuths & Secrets

A most curious, mind-tingling late night adventure at HMNS.

Are you good at solving mysteries? Can you untangle a web of clues, evidence, history and mystery? Are you looking for an out-of-the-ordinary adventure for you and your family, friends, co-workers or group? Then HMNS Sleuths & Secrets is for you! It all starts when you unlock a series of clues, riddles and objects found in a one of our HMNS Hermann Park exhibit halls for an escape room style experience. We currently have two options listed below to choose from!

In the Morian Cabinet Of Curiosities, you can explore the hall belonging to Ferrante Imperato, a 16th Century resident of Naples, Italy. While many believe he was merely an apothecary who liked to display his collections of unusual specimens, others speculate that in reality he was a dedicated alchemist. Did he solve the mysteries of transformation? Did he, in fact, turn a lowly base metal into pure gold? Will his specimens lead you to a hidden treasure?

In the Hall of Ancient Egypt, can you save the paranoid archeologist from the famed curse of the Mummy? After the discovery of King Tut’s Tomb in 1922 the media popularized the idea of ancient Egyptian curses. Egyptomania swept the globe! Can you escape the curse of the mummy and save the world while working together through puzzles and clues left behind by the archeologist who triggered the curse? Perfect for Young Professionals, family reunions, birthday parties, scout groups, teams, science clubs, student councils, sorority and fraternity councils and friends. Great for corporate team-building!
