The 40th episode of In Writing focuses on the art of letter-writing. Shaun Usher, who spoke to me last week from his home in Manchester, is the founder of Letters of Note, a blog that led to several very successful books and a star-studded live event (Letters Live). He has dedicated his career to finding the most brilliant, funny, insightful or poignant letters from all over the world and bringing them to a wider audience – whether that's a young Tom Hanks trying to charm the director George Roy Hill, or Albert Einstein's letter to a Sunday school class. Shaun speaks to me about falling in love with his wife and the letter-writing tradition at the same time; the massive research involved in his job; and the very finest letters he's read.
