Synopsis: Grand Central Murder was intended as a followup to the MGM "sleeper" Kid Glove Killer, with the earlier film's star, Van Heflin, appearing in a similar role. When bitchy actress Mida King (Patricia Dane) is bumped off in a private train car at Grand Central Station, police inspector Gunther (Sam Levene) gathers together all likely suspects. One of these is wisecracking private eye Rocky Custer (Heflin), who endeavors to uncover the genuine murderer himself before Gunther slaps the cuffs on him. Custer's seemingly casual, off-the-cuff methods of detection prove infuriating to Gunther, but guess who solves the mystery-and a particularly baffling one at that--by fadeout time? The film received a mixed reviews from the New York critics, who enjoyed the mystery angle but found fault with Hollywood's convoluted concept of Grand Central Station's floor plan and its unbelievably close proximity to a fictional Broadway theatre (even so, these critics also applauded the ongoing illusion of trains arriving and leaving throughout the picture).
