The Pinkerton cabal. Red Snow

Sarah Carlyle and Samuel Twain, two of the best agents of a secret branch of the legendary Pinkerton detective agency, arrive to Alaska in order to to stop a couple of individuals from summoning primordial forces that want to take over our planet once again. The Pinkerton Cabal is the branch specialising in the arcane and the paranormal, and their members have these unique skills that can stop monsters from becoming real. 

Javier Marquina sets the whole story as if it were a western, achieving a perfect blend between this genre and Lovecraft's horror.
