We're taking a break from The Mauritius Command to bring you a guest interview with Antonia Senior. Antonia is a book critic at The Times, as well as a writer, podcaster and journalist. But before she was any of those things, she was a Patrick O’Brian fan, and we had a great time talking to her about historical fiction, what makes O'Brian such a standout, and which other authors come close. With a little chat about espionage on the side!
