There’s a style of flash fiction I really enjoy writing, which revolves around two elements: being two to four paragraphs, and being non-chronological.
It’s fun to read, but it’s solving a puzzle as well as reading a story. I like the reader to learn the information before they know the significance. That way it creates this disjointed moment where you realise that a small passing detail was actually the crucial information, the conclusion to the story or a central plot point.
This relies on having a couple of key words that link the paragraphs, and just enough temporal indicators that the reader can piece it back together.
Anyway, I wrote this one ages back, check it out. 🙂
