A Door Fell Shut — Martha Albrand

Berlin, where U.S. agents await a defecting Soviet official who has mysteriously disappeared in the Eastern sector. Berlin, where a pampered young maestro with an aging mistress and a brilliant future is persuaded to play a spotlight role in a deadly little game of Who's Got the Spy. Berlin, twilight world of the Wall, where intrigue and espionage breed fear, suspicion and sudden death.
