This is a fast-paced, ever changing plot, that can make sense from any of the variations that come our way, yet, there is only one murderer...Better than average acting and a very young, Van Heflin, takes control from beginning to end and pilots this story to a very satisfying ending...It is visually, a very dark film but is what gives it the grit it needs. Takes place in Grand Central Station, but not in the main room, we all know of and have used, rather, in the bowels of this majestic building, which of course, is some Hollywood set. Very entertaining and engaging...I despise the overly used word, (Riveting), that every critic, cannot do without and has used at least twice in their careers, and that is also because it is not a riveting film. Very good, above average plot, but nothing and no one to afford the iconic, riveting, word ...!!!
