This is another question about guidelines. In the previous post I’ve asked about recreating famous plots. What if instead of recreating plots I just use plot elements?
Take The Hound of the Baskervilles scenario… say I create a crime mystery world, the investigation itself is an original work and has nothing to do with The Hound… however investigation does feature a brunch where one of the servants is caught sending the signals to someone outside the house with a candle, it does turns out that the signals aren’t meant for the actual villain of the story but for an escaped convict who happens to be servants relative. In the end, while the story itself is original the plot element from The Hound was clearly used (naturally a number of details are changed and all the storylets text is original)
