The Secret Service

The Feathered Spies (1x4)

Data di messa in onda: Ott 12, 1969

Aerial photos of a secret experimental World Air Force fighter plane are being offered on the black market, so Father Unwin and Matthew are assigned to determine how the photographer has managed to breach the restricted overhead access to Crayfield airbase. Their investigations lead them to pigeon fancier John Masden, who seems an unlikely candidate for espionage.
