Calling all code breakers, can you crack this secret wartime message, because spy chiefs certainly can’t…

Experts admit the note attached to the leg of a dead pigeon found in a chimney has left them baffled.

And they have asked any former code crackers to help.

Homeowner David Martin discovered the bird’s remains when he was refurbishing his house in Surrey and spotted a little red canister containing the message on Pigeon Service paper.

Spooks at GCHQ have spent weeks trying to fathom out what it means.

One said: “We didn’t hold out any hopes because the sort of codes that were constructed to be used during these operations were designed only to be able to be read by the senders and recipients.

"Unless you get rather more idea than we have of who actually sent this message, and who it was sent to, we are not going to find out what the code being used was.

“There are still quite a lot of people alive who worked in ­communications centres during the war and who might have some knowledge about this.

“It would be very interesting if anyone did have information if they could put it in the pot and we could see if we could get any further with it.”

About 250,000 pigeons were used during the Second World War to pass on vital messages by the military.

The one found in David’s chimney has 27 handwritten blocks of letters.

It may be based on a specific code book put together for a particular ­operation, which would probably have now been destroyed.

So what could the 70-year-old secret mean?

Perhaps the pigeon was bringing back information of the Loft-waffe or movements in the Bird Reich…
