The Margery Allingham Short Mystery Competition

The Mystery remains box-shaped, at once a prison and a refuge. Its four walls are, roughly, a Crime, a Mystery, an Enquiry and a Conclusion with an Element of Satisfaction in it. Margery Allingham

The Margery Allingham Short Mystery Competition is an international short story competition for unpublished mystery and crime writing. Open to all published and unpublished writers worldwide, the competition invites original stories in English of up to 3,500 words.

About the Margery Allingham Short Mystery Competition

This crime writing competition is open to all published and unpublished authors from anywhere in the world. It’s for short stories originally written in English of up to 3,500 words. All that we ask is that the story hasn’t been previously published anywhere, shortlisted for this competition or won any other competition. The competition is ideal for writers of mystery, crime fiction, detective fiction and Golden Age-inspired short stories.

Please follow Margery’s definition of a mystery to be in with the best chance of winning this international writing competition: “The Mystery remains box-shaped, at once a prison and a refuge. Its four walls are, roughly, a Crime, a Mystery, an Enquiry and a Conclusion with an Element of Satisfaction in it.” The way a submitted story matches this definition is awarded greater weighting in the scoring than any other criteria.

Entry to this short story competition costs £25 and the prize for the winner is £500 as well as a year’s membership with the Crime Writers’ Association.

Before entering, please read the terms and conditions carefully, then submit your entry via the online form.

How to write a winning story

We asked Martin Edwards, the inaugural winner of the Margery Allingham Short Mystery Competition for his top tips:

  • Read a wide range of successful short stories (not just crime fiction!) and ask yourself what makes them great.
  • Don’t kid yourself that writing a short story is much easier than writing a novel – it’s not.
  • Think about the effect you want the story to have on the reader.
  • The opening needs to arrest attention.
  • The end must leave the reader with a sense of satisfaction.
  • Between the beginning and the end: don’t waste a word.
