Gentlemen's Escape Room

We find ourselves in 1841. Thomas Ainsworth is the successful director of the local agency of the Dutch Trading Company (NHM), with his own textile factory on the banks of the Regge. He is 45 and in the prime of his life. Until he, on February 13, 1841, is found dead in the Gentlemen's Room of Havezate Eversberg, the place where he lives and has his office... What happened to the man who has spent the past decades establishing the textile industry in Twente? Is it a coincidence that Thomas nearly fell victim to multiple accidents that month? What is the role of the NHM? And why does the name of Douwes Dekker, the writer of the famous book 'Max Havelaar, the coffee auction of the Dutch Trading Company', appear in this story?
