Cover picture PLAN52 Escape Room in London

clueQuest's escape room mission

PLAN52 is one of our top secret locations and a fortress for highly classified archives and data. However, something terrible has happened: four of our agents who were stationed there have vanished without a trace. We now have proof that this was the work of Professor BlackSheep who had help from a clueQuest insider.

Mission Brief

It is up to you and your team to investigate this risky matter and learn the identity of the double agent. But be careful, Mr Q has confirmed that the traitor has managed to reset the security device of the facility! From the moment you set foot inside PLAN52 you will have just 60 Minutes to learn who the double agent was and deactivate the device before the entire facility detonates.

Super fun for families

This was brilliant. Sadie was really fun, kind and patient. She helped us get the right balance between challenge and progress (I was playing alone with my 7 year old son). She made it a really special occasion for us.

Mission Bees Success

Found this place via the Room Escape Artist blog. Plan 52 was an excellent mission to do with my parents, who are less experiences with escape rooms. It's super newbie friendly, but different enough to entertain veterean players. Super charming aesth... more


One of my favourite escape rooms, can't wait to go back and do the others. Ok to do in any size group - we did as a three which seemed good but would be fine to do as a two.

Room? Escaped…

Had a great time for a friend’s birthday! Senna was lovely and got us really into the storyline. Her enthusiasm became ours, and we know Central is counting on us. We will be back…

Great fun!

Great fun! First time I'd done an escape room - would definitely do it again! Was challenging but there was also help available, if needed. Really enjoyed it!


Is good for all ages and builds team work and eas very entertaining would happily go again and am sad that it is over


Plan52 was amazing, it was so well planned and put together and it was so satisfying to solve. Ez was fabulous as well, they really got us into the part and were so welcoming, it made such a difference. If I could give more than 5 stars I would.

Great activity solving puzzles

Great fun and enjoyed afternoon working together solving the puzzles. Rowen from the control room was very friendly and extremely helpful. Her hints weren’t patronising and were very helpful as this was our first time.

Lovely experience

My first escape room experience in a while and it was super fun! The storyline was creative and all the props in the room were so well-planned and innovative. Definitely worth every penny

Great! Will definitely do another one soon!

This was my first time and I really enjoyed it! It was challenging without being too difficult and I loved that we had to work as a team. Rowen was a great host.


My first experience of an escape room and it was brilliant.
You get some help if you struggle with anything but I would def recommend it

Amazing 11th birthday experience

I took our daughter and 4 of her friends to Clue Quest for her 11th birthday. They loved every minute of Plan 52 (especially the last 5 minutes with the increasingly tense countdown to our escape in the nick of time!).

The puzzles were pitched ju... more


The room was so much fun and Trudi was beyond brilliant! Would absolutely come back for the other rooms

Great teambuilding experience

A great teambuilding experience! Rowan was very attentive and fun. Explained everything properly. We managed to escape at the end with a little help!

Christmas Cracker

The Christmas version of this game was the perfect way to end our visit. Decorated with garlands, baubles, and Christmas stockings there were also 2 striking nutcrackers and an unassuming gingerbread man to test your wits. Unmasking the fiendish Pro... more

It’s quite a challenge ! The crew , especially agent Senna ,were so entertaining and welcoming ! Thanks for making it a great experience ! Sinéad Ireland

Great experience - highly recommended

I booked this so me and my mum would have something fun to do over Christmas. We had a fantastic time even though we are complete rookies. We were given just the right amount of hints to nudge us along, and even an extra 10 mins at the end because we... more

Christmas Cluequest

Fantastic experience from start to finish. The team look after you, especially those new to escape rooms.

We visited for our work Xmas Do and were able to have teams compete against each other at the same time. Everyone left buzzing!

Adrenaline rush

Had such a blast, there was an abundance of clues/tasks, our group of young teens were so excited each time something was right, the clue quest staff was helpful and when we finally got out it was such an adrenaline rush. Thanks so much clue quest ,... more
