Wordsmag short story competition. The theme is murder, max word count is 2,000 words, it's free to enter and there's a cash prize of £50.
Btw, after mentioning Ad Hoc Fiction's weekly flash competition, I decided to have a try. The first prompt I saw generated a 1,000 word piece instead of 150, so I sent that off to a magazine and tried again last week. My story made it through the first round. You can read it, and others here. Whichever is voted the best will win.
The competition is still running. The prize each week is free entry into the Bath Flash Fiction Award - and the prize for that is £1,000.
