Great cast (Cary Grant, Ginger Rogers, Walter Slezak in his first American film) in an amusing comedy-drama about WWII intrigue across Europe at the start of the war. The plot at times gets dark and complicated, but the many touches of humor keep it from getting too heavy.

I was not aware of this film until I happened to catch it on TCM, but it's really worth seeing if you get the chance. As always, Grant and Rogers are captivating, and Slezak makes for the perfect bad guy. Good supporting cast, too.
