At 8, TCM showed a mystery I've never seen before: GRAND STATION MYSTERY with a terrific cast including such MGM stalwarts as Van Heflin, Connie Gilchrist, Sam Levene, Tom Conway, Frank Ferguson, Cecilia Parker, and Virginia Grey.
I did figure out who committed the crime about halfway through the film, but not the method of murder. That was a surprise.
And throughout the film, I kept thinking that Heflin and Grey's parts could easily have been played by William Powell and Myrna Loy, and this could have been another THIN MAN mystery.
