Swamp Noir. Yes, it's a thing now and I'm on board.
With all the attributes featured in a Noir story, but set in a Louisiana swamp bar, (The Grinnin' Gator),in the 30's. Prohibition is in effect and rotgut is being served while the women dance. Their clientele does not consist of doctors and lawyers; there's maybe a full set of teeth between them.
That's all I'm going to say about the plot. There is nothing about this story that is tame or politically correct, so if you're easily offended, I suggest you pass this one up. But if nothing I've said has turned you off so far, then it's to you that I recommend this Swamp Noir creature feature.
Have fun and don't blame me if you have dreams about man-eating gators!
