Anachron Press has a new anthology out, for stories in the 4,000 to 8,000 word range:
Crime Net is essentially an anthology of detective, mystery, or noir stories. All kinds of protagonists are welcome from both sides of the law. You could write about a noir-style detective hunting down a notorious hacker, or write from the hacker’s point-of-view as he is forced to work for an insidious crime family, or anything else that captures your imagination. The only stipulation is that it must feature IT and the ‘Net within its narrative.
Payment is a modest £10 and a contributor copy.
