I think this was one of the many shows forbidden me when I was ten, but obviously mainstream 50s TV (a "Panic!" marathon would be a great Thanksgiving Day). The only one I remember has of course the heavy voice-over at the beginning. A man is on a subway with three men sitting opposite him. All are wearing generic 50s suits. "Your friend seems to have had one too many," he says. The heavy voice-over then comes in ending ominously "... the man in the middle was dead." At the next stop, the 'hero' reaches down for his newspaper and bolts out the door. The pre-commercial shot is a close-up of the face of one of the three men (with gun) pressed against the closed subway door ... (The memory trail now grows cold.) Think of all the great things I could have done in life if my brain were not cluttered with things like this.
