Musical tales

Kazuo Ishiguro's latest book, Nocturnes has left me thinking, which isn't a bad thing. It is made up of five short stories, all following a musical theme, and although the tales were involved, and the characters were realistic, the endings were left for the reader to imagine. I suppose this is a clever way of writing and involves your reader, but sometimes, you just want to know what the author wants to happen. Anyway, I might try reading it again and find what I am missing.
