Robert Stack hosted this fascinating series in which mysterious cases were examined, including everything from UFO sightings to murders. The series has been on the air since 1987, and is currently hosted by Dennis Farina on the Lifetime Network (yeah, we don't know, either). Its spooky theme starts out with heavy drums that give way to the tinkering of piano keys, as the narrator (in the above and more recognizable version, Stack) gives a preview of the evening's stories.
