In search of Mary Shelley: the girl who wrote Frankenstein

Mary Shelley was brought up by her father in a house filled with radical thinkers, poets, philosophers and writers of the day.

Aged 16, she eloped with Percy Bysshe Shelley, embarking on a relationship that was lived on the move across Britain and Europe, as she coped with debt, infidelity and the deaths of three children, before early widowhood changed her life forever.

Most astonishingly, it was while she was still a teenager that Mary composed her canonical novel 'Frankenstein', creating two of our most enduring archetypes today.

The life story is well-known. But who was the woman who lived it? She's left plenty of evidence, and in this fascinating dialogue with the past, Fiona Sampson sifts through letters, diaries and records to find the real woman behind the story.
