Authored by an American writer who went to Denmark in the early 60's for a CBS documentary on the rescue of the Danish Jews. While he interviewed many of the relevant personae in the October 1943 flight to Sweden that rescued some 7200 Jews from the claws of the Nazis, his version, though it makes good reading is a bit overly dramatic in spots and now somewhat out-of-date with more recent and more authoritative historical record. But in its day, it became a sort of "classic".
