This is the second time in two days that I've stumbled across a call for submissions that involves characters created by William Hodgson. I'm really going to have to find some of his work to read. Anyhoo, this call is for an anthology titled Charnacki: The New Adventures. They're looking for shorts of 3000 to 6000 words based on the character Charnacki the Ghost Hunter. This was a short notice call when it was first posted and now they've extended the deadline to May 31. Still short notice :) Payment here is two copies. You can read all the details here.
UPDATE: I was searching out some short stories by Hodgson and found a group of Charnacki stories for you to read if you're thinking of submitting to this anthology.
