Detective Comics, Vol. 1

Bruce Wayne's fiancee has been cast in a movie. However, the star is murdered, leaving Julie next in line, and the list of suspects is not a short one. The murdered Lorna Dane (who is neither green-haired nor a mutant) recently broke it off with her lover. The movie's original director was fired for unreliability. A local mobster was refused protection money. It could be any of them, or someone else entirely.
