When Mum and her three children rent a country cottage, the arrival of Dad coincides with the manifestation of a ghostly crying woman on the telephone, radio, record player and television. Made for ITV Schools' 'Middle English' strand, this three-part drama was later turned into a stage play by writer Jan Mark and published in Longman's 'Star Plays' series in 1987. (From IMDb).
