Sitcom by James Cary, set in Bletchley Park in 1941. Three code-breakers are forced to share a draughty wooden hut as they try to break German ciphers. Unfortunately, they hate each other. Gordon is convinced that Hut 33's recent run of luck is thanks to his lucky mascot, Mr Pickles. But Archie is determined to prove that it's all down to natural intelligence and decides to put an end to Gordon's childish superstitions. At which point their luck promptly runs out; none of the codes make even the slightest sense. They are forced to move into Hut 13 - although a mystery surrounds the whereabouts of the former inhabitants. Perhaps the rumours about the Devil's Equation are true after all. Charles ......
