SEASON FINALE: Ozzy Osbourne, and the rest of Black Sabbath, are featured guests on tonight’s CSI season finale, which also makes room for a killer that, like the villain in The Following, gets his inspiration from a classic literary work. This time, though, the source material is Dante’s Inferno. Coincidentally, that same source material also was the inspiration for the name of my underground newspaper in 1969. That’s right: Seventh Circle.
