Fiona here. This weekend I'm running a contest to win a free escape room experience at International School of Spies. The prize is a free game for one team, with runners-up winning a free game for one player.
GCHQ, the UK's code-breaking intelligence service, is celebrating its centenary in 2019. What was its name when the agency formed in 1919? Send your answer by 19:19 on Monday (send a message via the Escape from Britz page, not to kumamoto-i) and the winning team can play their game anytime in November. Please don't answer in the comments!
