I'm on the fence about posting this but because it's a crime fiction market...
The call is posted by Stephen Bentley and he's looking for indie authors to contribute to an anthology of "Murder Mystery Short Stories". There is a "Good Reads Event" thingie that you need to sign up for. He wants each author to submit three stories of 1000 to 3000 words using the theme of Murder Mysteries but also the three stories need to have another theme (your choice) that ties them together. The deadline is May 1, 2019 and payment is a royalty split.
Now here's the catch. Each writer will have to pay a share to have the stories edited and if they decide to do a paperback edition you'll have to pay a split for that also. Now if you are an indie author you probably know what to expect in the way of fees for this one.
You can find the details here.
UPDATE: As of February 8, 2019 Mr. Bentley has filled all his open slots and the call is now closed.
