I don't think Israel can be ruled out due to 'European ancestry'. Israel did not exist until WW2 and in those post war years anyone in Europe with Jewish ancestry could migrate to Israel and get citizenship, complete with a passport. The 'English with an accent' would fit with Israel too. Around twenty years ago I did have some friends where all kinds of unusual contraband items were exchanged, up to and including passports. I was not in the market for buying one myself, however, this just seemed to be standard capitalism as applied to the black market - you could get a good fake passport or pay more and get an even better fake passport, i.e. from a decent country. I doubt that the lady was an international cocaine dealer on the run and in need of lots of passports to get across Europe but stranger things have happened and you cannot just assume the lady was a spy. I have not studied the story any more than the article, however, the travel pattern is that of someone on the run. If you are up against a police (or intel. service) that has proper resources to track you then you are obligated to move every day. This is the most expensive lifestyle to have, not a sustainable existence. In this existence you need to be totally unpredictable, so where you stay may not have much significance other than a need to hide. In this mode of existence you also run out of friends quite quickly so staying in hotels becomes how it is done until the money runs out or you get caught.
