In 2017–18, at the start of her ‘tenth decade’, the popular historian, author of the Pax Britannica trilogy, and travel writer Jan Morris (b.1926) decided to keep a diary of thoughts. Ranging back and forth over an extraordinarily interesting life, but also examining the joys and frustrations of old age at home in North Wales, Morris’s 188-day diary treats us to her opinions on anything that comes to mind – be it Ovid, walls, whistling or Brexit. Slightly off-mint.
