It was lilting and wistful, and she could have sung the melody if she had wished.'Alright?' He raised his eyebrows inquiringly.'Yes. Exactly.'It was effortless and perfect, and he played it through to the end, closing with the softest and most delicate chords, which hung and faded in the quiet hall like the grains of dust raining through the evening light. Ruth was touched. It was all she had wanted. He did not move until there was complete silence again, then he closed the lid without saying anything, and stood up, shoving back the chair. ... 'What was that piece?''A Brahms waltz.''Hasn't it got a name?' she wanted it to remember.'Number fifteen. Opus thirty-nine.'It hadn't sounded like numbers to Ruth.
