Foreign Intrigue (1951-1955, syndicated) First Jerome Thor, then James Daly, then Gerald Mohr as European-based journalists often involved with bad guys and spies.
Syndicated under various titles including Overseas Adventure, Dateline Europe and Cross Currents. Some interesting street scenes in major European cities.  Definitely a period piece.
