10 things you didn't know about Jekyll and Hyde

9: Mr Stevenson and Dr Hyde

The name Hyde took on a new significance for Stevenson in a strange episode which occurred years after the novel was published.

It concerned the now-famous priest Father Damien, a missionary who worked at a leper colony in Hawaii. Father Damien helped build cottages, dress the lepers' wounds and even make their coffins before succumbing to leprosy himself in 1899. Shortly after, a Presbyterian minister named Dr Hyde wrote a much-publicised letter condemning Father Damien for alleged immorality and corruption. Stevenson was so outraged that he wrote a counter-attack, rubbishing Dr Hyde's claims. Stevenson's intervention helped save the reputation of Father Damien, who has since inspired books and films and is now widely expected to be made a saint.

10: And finally...

Here's a nice little factoid to please the book nerds among us. Did you know that the famed novelist Graham Greene – writer of modern classics like Brighton Rock and The End of the Affair – was related to Robert Louis Stevenson?

Greene's mother, Marion, was Stevenson's first cousin. How trivia-tastic's that? Commit it to memory - it's bound to come up in a pub quiz at some point. Probably.
