Here is this week's speculative fiction writing prompt. I'm not labeling it this week, so take it whatever direction you choose.
A candle flame flickers in a strange pattern that can only be a code.
As always, feel free to use this in any way you choose. There's no need to give me any credit for any story you come up with. Of course, I never mind if you do give me credit for the writing prompt, but it's not necessary.
