Seasonal escape room type games set at the Mill.

Murder at the Mill is back for its third year at Mill Green Watermill & Museum, and we'll be running Friday to Sunday from July 11th to August 24th 2025!

Mill Green is a sleepy village where nothing much ever happens… that is, until a murder is discovered! The local constabulary are baffled—there's only one thing to be done. They call on Clue Company, the world's greatest detective agency, to see if its super-sleuths can crack the case. Are you and your fellow investigators up to the challenge?

This intriguing escape room whodunnit will take you around the beautiful grounds of Hatfield's 18th Century working watermill as you race against the clock to solve the crime! Choose your own route around the mill, tackling the challenges in whatever order you wish. Each puzzle you solve will give you another clue to the mystery: once you've gathered them all, it's time to put your detective skills to the test!

Who committed the murder? Where did they do the deed? Which weapon did they use? These are the questions you and your team will need to answer. You'll have exactly one hour to unravel the mystery and close the case.

Entrance to the award-winning Mill Green Museum is included in your booking, so once you've solved the mystery, you can explore the exhibitions at your leisure, or celebrate your win with a cream tea at the Miller's Kitchen Cafe! Our players can enjoy an exclusive discount on cream teas if they book a 'cream tea' ticket in advance.

Murder at the Mill is an original experience created by Pier Pressure Welwyn, inspired by a beloved classic board game and Pier Pressure Brighton's Clue Company game. It is NOT the same game as Clue Company Brighton, and has all-new puzzles and challenges.

Mill Green Museum has separate opening hours to our escape room experience, so if you would like to see the museum as part of your visit, please check their website before you book!
