SUPERSLEUTHS grab your magnifying glass for a family fun day in Letchworth GC this weekend which gives visitors the chance to try to ‘crack the code’.

The First Garden City Heritage Museum’s Code Breaking Fun Day comes to the town on Saturday promising games, trails and puzzles.

It’s your chance to find out all about the code breaking at Bletchley Park, with volunteers demonstrating a genuine wartime Enigma machine, explaining how it worked and how the ‘unbreakable’ German code was cracked.

There will also be members of the Bombe Rebuild Team present, who helped produce a replica of the original Bombe machine made in Letchworth GC.

Open from 11am to 4pm with no need to book, entry at the Norton Way South museum costs �1 for non residents, 50p for residents and students, while under 16s go free.

All children must be accompanied by an adult - for more information on this and other museum events visit www.gardencitymuseum.org or call 01462 482710.
