Voices in the Garden (1993)

Sir Archie and Cuckoo Peveril have lived in elegant splendour on Cap Ferrat since the end of the war. But the heady days of extravagant socialising have gradually dwindled, and for Cuckoo the villa has become a prison. Then an attractive young couple arrive, resurrecting the tensions and sexual rivalry between Archie and Cuckoo, and forcing all four to learn about themselves.
