were there any really notable successes in German espionage?
i can't recall the name of the individual but one german agent that comes to mind was a Portuguese fellow who radioed ship traffic in the Mediterranean and helped tip off the Germans about operations.
I like reading the declassified materials from the british, with their 65 year release policy, it has certainly opened up alot of information for us. It also amazes me that there is still such a compulsion to protect the secrets of what has long since become an obsolete war.
