Saucy short stories often have elements of surprise. They might have unexpected plot twists that keep the reader on their toes. For example, in a saucy detective short story, the real culprit could be the least suspected character.
One saucy short story is 'The Most Dangerous Game'. The idea of a man being hunted for sport on an island is quite saucy in terms of the danger and the moral implications. There's also 'An Occurrence at Owl Creek Bridge', which has a saucy way of playing with time and the reader's perception, creating a thrilling and somewhat saucy story.
I think there may be a misunderstanding as the term 'charters' doesn't seem to have an obvious meaning in relation to this story. Maybe it was a typo? If we consider the characters instead, they are significant as they drive the plot. For instance, Craig's relationships with his friends and family change throughout the story as he grows.
One 'kinda scary story' could be about a haunted house. There's a old, dilapidated mansion on the outskirts of town. People say that at midnight, strange noises come from it, like the creaking of floorboards and the moaning of a long - lost soul. Lights flicker in the empty rooms, and if you look closely, you might see a shadowy figure in the window.
