Mary Harter, an old lady in her seventies, has a consultation with her doctor, who advises her that she has something of a weak heart and should avoid undue exertion to ensure many more years of life. Dr Meynall also tells Mrs Harter's beloved resident nephew, Charles Ridgeway, of the advice he has given, adding that Mrs Harter should be cheerfully distracted and avoid brooding. To this end, Charles persuades his aunt to have a radio installed. She resists at first, but quickly comes to enjoy the programmes that are broadcast. One evening, when Charles is out with friends, the radio suddenly emits the voice of her dead husband, Patrick, who tells her that he is coming for her soon. Although naturally shocked, Mrs Harter remains composed but thoughtful.
