Inklings Press - Anthology Calls

Inklings Press has posted an anthology call for "Tales From Alternate Earths".  They're looking for stories of 3500 to 6000 words.  The deadline is April 30 and payment is a royalty split.  You can find the details here.  While this is basically a spec fiction anthology you mystery writers can do alternate histories of famous crimes.  Perhaps Sherlock Holmes solves the Jack the Ripper crime?  Just let your imagination take you where it will.
