Ghost Noir (2014)

The alternate world of Ghost Noir looks like our own 1940s... with gritty differences. Demons roam the streets. Death is almost impossible. And no one is older than sixteen. Detective Camille Delatore is trying to ignore the disappearance of her free-spirited brother by throwing herself into her work, but all roads lead to Roman, and Camille realizes their world holds secrets beyond imagining.
