Adam talks to Stephen Foster, author of the new book 'Zoffany's Daughter: Love and Treachery on a Small Island'.
The book details a forgotten episode in Guernsey's history, an 1825 incident that became one of Britain's first ever child custody battles, finally ending in a dramatic showdown in a packed Royal Court.
Stephen explains how he came across the story, why he finds it so fascinating, and what this seemingly minor incident can tell us about history and the writing of history.
