Although the show is U.S. (more like six TV movies than a series at seventy minutes each) three of the episodes are Euro affairs, one set in London, one in Lisbon and one in Rome.
Plenty of known faces in them, in the one in London you see the likes of George Cole, Fiona Lewis, Garfield Morgan, Michael Shears, Irene Handl, Tommy Godfrey and Alan Lake, in Lisbon there's Peter Vaughn, Tom Adams and Bruce Boa and in Italy Rossano Brazzi, Raf Vallone, Luciano Pigozzi and Agostina Belli.
