One of the reasons I wanted to publish The Devil in Snakeskins is that the professor is completely amoral. So often in current fiction we have bad guys that only kill other bad guys or serial killers like Dexter who have a moral code. Blah! I want a bad guy to be like Henry Fonda in Once upon the Time in The West. 100% evil and I think that’s what you’ve done with your creation.
