Write a story about anything you want to and the only rule is that it has to incorporate something historical that happened/is happening.
It can be something mysterious like the disappearance of Amelia Earhart or the fate of the Romanovs. Or it can be suspenseful such as the assassination of Archduke Ferdinand or the tension in a country fighting for independence. It can be something that happened in the past or something currently happening.
Pretty much anything you want as long as it has some historical aspect. You can decide what length it will be and you can also submit up to two entries.
Good luck!
