The Margery Allingham Short Story Competition is open until February 28, 2018.
Submit stories up to 3,500 words. Your story should fit into crime writer Margery’s definition of what makes a great story: “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.â€
Prize: £500 plus two weekend passes to Crimefest 2019 and a selection of Margery Allingham books.
Entry Fee: £12
