http://www.bbc.co.uk/news/uk-20456782 Britain's top code-breakers say they are stumped by a secret code found on the leg of a dead pigeon. The remains of the bird were found in a chimney in Surrey with a message from World War II attached. Experts at the intelligence agency GCHQ have been struggling to decipher the message since they were provided with it a few weeks ago. They say it may be impossible to decode it without more information - some of which could come from the public. The message was discovered by David Martin when he was renovating the chimney of his house in Surrey. Among the rubbish, he found parts of a dead pigeon including a leg. Attached to the leg was a red canister. Inside the canister was a thin piece of paper with the words "Pigeon Service" at the top and 27 handwritten blocks of code.
