I have racked my brains but I still do not remember them going. And now here, neatly stored on miles of shelving in the Penguin archive, are the reasons. Puffins. Not the excitable avian inhabitants of the Hebrides, but the books. Penguin invited me to spend the day here after an article I wrote hinted that it would be my Xanadu. These books are my memories. My entire childhood is on these shelves.
