Illicit Signals Bletchley

Step back in time to 1940s Bletchley Park, a world of espionage, code breaking and secrets. It was here that men and women, both young and old, cracked German codes and unveiled war winning secrets, but these men and women kept secrets of their own, both from each other and the public. 

Mechanical Thought is back with their hit show Illicit Signals Bletchley for another month long run at the Crypt! Follow in the footsteps of real life cryptologists as Bletchley Park goes through its most pivotal moment. Crack codes and decipher messages to uncover their private lives and make the tough decision of whether to keep their secrets or spill the beans.

When it comes to an illicit past; is it better to be honest or stay silent?

How far could you take a white lie?

Illicit Signals Bletchley combines historical drama with rewarding codebreaking to create a fun, stimulating evening.

'There is nothing about Illicit Signals Bletchley that can be faulted... quite simply perfection.'
