Caroline Taggart worked in publishing as an editor of popular non-fiction for 30 years before being asked to write I Used to Know That, which became a Sunday Times bestseller. Her later books include My Grammar and I (or should that be 'Me'?) and Her Ladyship's Guide to the Queen's English. As a result, she has appeared frequently on BBC Breakfast and on national and regional radio, talking about language, grammar and Pythagoras' theorem. With her editorial hat on, she also visits writers' conferences around the country, advising would-be authors on how to get published and learning what their place names mean.
