Editor Jochem Vandersteen has issued a call for submission to "Shamus Sampler - Vol. 2". He's looking for PI (licensed or unlicensed) shorts up to 5000 words. The deadline is March 1, 2014. This is a non-paying market. Mr. Vandersteen is looking to make this a quarterly project if all goes well. You can read the details here.
