British intelligence agents are working on deciphering a coded message
that has remained a secret for nearly 70 years — attached to the leg of
a hero World War II carrier pigeon. Found in the chimney of 17th-century
home in Bletchingley, Surrey, the bird’s skeleton was found in 1982 when
the home’s current owner David Martin decided to restore the fireplace.
“I started finding bits of a dead pigeon. We thought it might be a racing pigeon
until we spotted a red capsule,” Martin told reporters. The small red cylinder
contained a mysterious cigarette paper-sized encrypted message.
