Looking for any great Supernatural Noir novels with a creepy atmosphere & thrilling mystery

I have been enjoying Film noir & Neo-noir movies alot lately, particularly Shutter Island, & Night of The Hunter.

Even those aren’t technically Horror in a conventional sense, I think I enjoy that they have a creepy atmosphere to go along with the thrilling plot.

It would be a Detective in the 1920s-1950s investigating a grisly murder & feeling haunting presences at crime scenes, maybe ghosts leading him to clues.

Could be something more out of leftfield like Vampires, the Occult, unhinged Science Experiments with the unknown, or anything else.
