‘A writer’s notebook is full of the sound of atmosphere…’ This week, Sally is teaching a course on detective fiction. Emerging from her meditations on Wilkie Collins’ novel The Moonstone, follow her on a journey through the light and the dark places of the world, and the variegated truths of writing and life. Miss Cull, a frequent guest on the podcast, can also be found in Sally’s latest book, The Green Lady, available from all good booksellers. This episode was edited and produced by James Bowen. Special thanks to Andrew Smith, Violet Henderson, Kris Dyer, and Maeve Magnus.
