Anna Mazzola's acclaimed debut novel, 'The Unseeing', focuses on a real murder case in London in 1837. Sarah Gale, sentenced to death for her role in the murder of Hannah Brown, protests her innocence - so why does she refuse to say what really happened?
Speaking at the Alderney Literary Festival, Anna tells us why she became fascinated with the case, why writing about real historical figures is tricky, and why she thinks we make entertainment out of murder in the first place.
