Humphreys is a great writer (Nocturne, The Evening Chorus, The Lost Garden). Her new book is fascinating because the first half is a personal account of her writing process: start with an idea, in this case an obituary of a reclusive Scottish woman who was a renowned salmon-fly dresser. Humphreys describes the essential questions: What is the story? Whose Story is it? How are you going to tell the story? The second half of the book is the imagined life of the Scottish woman; very entertaining.
