Things the Dark Has Always Held — Terry M. West

Baker Johnson is a psychical researcher, demonologist and exorcist living in 1930s New York City. Brilliant but deeply flawed, Baker has an otherworldly perception that allows him to read people with but a glance. In Things the Dark has Always Held, Baker is approached by a dangerous mobster known as Johnny Stücke. Baker's black room, a place where haunted items are cataloged and kept, holds an ancient item that Stücke is determined to possess. Baker is introduced to the secret society known as the Night Things. And he may be the only thing standing between the world of man and the most dangerous threat it has ever known.
