87 Bedford is seeking submissions for the first issue of their "Speculative Mystery Anthology". They're looking for stories of 2000 to 7000 words that combine mystery with one of the speculative fiction genres. The deadline is May 31, 2017 and payment is $30. You can find the details here.
UPDATE: According to Ralan.com this market was closed by the editors. Now, I don't know if that is for just the magazine or for the anthology also.
