The Tightening String — Ann Bridge

This novel records the lives of a group of English diplomats in Budapest from the Spring of 1940, up to the entry of the Germans which compels them to leave in Easter 1941. Crossing the Russian frontier en route for Moscow and the U.S.A., an episode at once dramatic and distinctly comic, sees the characters' main pre-occupation as less about their own predicament than the desperate and sustained endeavour to send food and clothing to the 44,000 British prisoners-of-war in Germany, during those first months when no Red Cross Parcels from England reached the camps. A touching love-story, a personal tragedy, and a disconcerting glimpse of treachery are skilfully interwoven in this revealing book.
