Author David James Keaton has posted an anthology call for "Hard Sentences: Crime Fiction Inspired by Alcatraz". He's looking for stories of 2000 to 3000 words set in Alcatraz. He's also posted a list of ideas for those coming up short on the muse side :). The publisher is Broken River Books and payment is pro to semi-pro based on length. The soft deadline for submissions is September. You can find all the details here.
