There's an imposter amongst us... ‘The Fortunes of Perkin Warbeck’ (1857), is 'Frankenstein' author Mary Shelley’s fictionalised account of Perkin Warbeck, the 15th century pretender to the English throne. Backed by a band of loyal Yorkists, Warbeck rose up against King Henry VII, claiming to be Richard, Duke of York and rightful heir to the English crown. The novel follows Warbeck’s adventures across Europe and England as he attempts to take back what is rightfully his. The character of Perkin is thought to be based on Shelley’s husband, the poet, Percy Bysshe Shelley. Mary Shelley (1797–1851) earned her place in the pantheon of British novelists with her ground-breaking Gothic novel ‘Frankenstein’ (1818). Considered one of the first true works of science-fiction, the book became an instant bestseller. But she was far from a one-hit-wonder, producing a host of other novels, including 'Valperga', 'Perkin Warbeck' and 'The Last Man'. Most were not well received in her lifetime, though, only being fully appreciated from the 1960s. She moved in a circle of famed 19th-century writers and philosophers. She was married to the poet Percy Bysshe Shelley and spent time with Lord Byron. Her mother was the philosopher and feminist activist Mary Wollstonecraft and her father was the political philosopher William Godwin. Mary Shelley’s work has been adapted for TV, stage and film on many occasions, with Boris Karloff famously playing Frankenstein’s monster on screen in 1933. Other adaptations include ‘Mary Shelley's Frankenstein’ (1994) starring Kenneth Branagh and Robert De Niro and ‘Viktor Frankenstein’ (2015) starring Daniel Radcliffe and James McAvoy. Most recently, Elle Fanning portrayed Mary in Haifaa Al-Mansour’s film ‘Mary Shelley’ from 2017.
