Can you solve the crime committed at St John's Gate 280 years ago?

About this event

Someone has been leaking parliamentary debates to The Gentleman's Magazine, a treasonable offence in the 1740s. Come and solve this 280-year-old crime in the very room that it occurred!

For a limited time only, the Museum of the Order of St John opens up its Council Chamber and revisits the room’s historic use as the editorial hub of The Gentleman's Magazine, one of the most widely read publications in Georgian London.

Players will have 60 minutes while the editors are out to lunch to snoop around and figure out who has been causing international uproar by leaking parliamentary reports. By using your powers of deduction and lateral thinking, can you solve the mystery?

Even historians have struggled to uncover this secret over the years. No previous knowledge needed. Keen observation and exceptional teamwork will serve you well in identifying the rogue reporter.

The Council Chamber is on the first floor at the heart of the historic Tudor gateway, accessible by stairs only. Please contact us if you require level access as it is possible to relocate the Escape Room to the ground floor out-of-hours:


What is an Escape Room?

An Escape Room – sometimes called a Puzzle Room, a Crystal Maze, or an Exit Game – is an exciting game in which a team of players are ‘locked’ in a room and work together to solve a series of puzzles and uncover clues that lead to a final answer to win the game and escape the room, within 60 minutes.

What to expect

On arrival, you will have a 5-minute briefing with our Games Master who will assign your task and explain the house rules. After that, you will be escorted into the Council Chamber, where the 60-minute timer will commence. To escape the room, start searching the space for clues! Look for patterns and connections and share your findings with your teammates. If you need any assistance you can go to the video camera and ask for a hint. For adult groups we give out 3 hints, so use them wisely!


We will be running the Escape Room one Saturday a month but we can also arrange games at other times to suit your group. Email us at with your preferred timings. We recommend arriving 10 minutes before your game is due to start.

How do I get to the Escape Room? 

You can find information on how to get to the Museum of the Order of St John here. Please let reception know that you have come for the Escape Room and a member of staff will collect you.  

Are you locked in a room?

No, you are never going to be physical trapped inside a room! If you feel overwhelmed at any time, you are very welcome to exit the room and sit with our Games Master.

How do you escape?

To escape the room, start searching the space for clues! Anything attached to the walls and the paintings are not part of the game, so look at the objects in the room and share your findings with your teammates.

I experience claustrophobia, can I play?

There is opportunity to exit the room at any point if you feel uncomfortable. If you would like more information or to see photographs of the space in advance, please contact us at

Do I need to know a lot about history?

No previous historical knowledge is required to play the game. It’s all about solving puzzles and thinking laterally.

What happens if you can’t complete the puzzle within 60 minutes?

If you don’t complete in time, don’t worry! It is exciting to finish within the time, but it is still a lot of fun for your whole team. Once the 60 minutes are up, you can go over the missing pieces with the Games Master.

Can I arrange a time outside of the times I see online?

Yes, please email us at and we will arrange a time that works for you and your team.

Can you cater for Corporate or Private Events?

Yes absolutely. Please get in touch with us with your requirements and we can create a bespoke package.

What age do you need to be to play?

The game is targeted at ages 18+. Children aged 8+ are very welcome too but must be accompanied at all times by their parent/guardian. Please let us know in advance if you’d like to bring a younger group. The Games Master can provide additional clues as needed.

How many players can be within a team?

The maximum number we allow within a team is 6 people.

How much does it cost?

Each game costs £120. With six players that is £20 per person.

Do you offer concession rates?

Visitors with a disability may bring a carer for free. Otherwise, there is one set price for all groups.

I require level access, can I still take part in the Escape Room?

The Council Chamber is located on the first floor of the historic Tudor Gateway and is only accessible by stairs. However, please contact us if you require level access. We can set the Escape Room up in an alternative location on the ground floor Museum Galleries out-of-hours. The Galleries have step-free access throughout and accessible toilet facilities.

What is your cancellation policy?

If you wish to reschedule or cancel your booking please let us know by emailing at least 14 days in advance to receive a full refund.

Covid-19 secure procedures?

Although legal restrictions have now been relaxed, we continue to encourage visitors to wear a face covering when visiting the Museum if they can. Hand sanitiser is available  on arrival. If you become unwell before your visit, we encourage you not to attend. We will do our best to reschedule your game.

How can I let you know if I am running late?  

If you are running late, please phone our museum reception on 020 7324 4005 and let us know how delayed you expect to be. 

Can I take photos or videos in the Escape Room? 

We do not allow photos or videos to be taken inside the Escape Room in order to maintain the mystery for future players. We do, however, allow for a team photo afterwards next to the timer to show how long it took you to complete the room.  

Is there a dress code? 

There is no dress code, but all heels thinner than 20mm must have plastic coverings in order to protect our historic floors.
