Candle in the wind
ReelzChannel takes a break from obsessing over John F. Kennedy's assassination to focus on the death of another beloved public figure in "Princess Diana: Behind Closed Doors" (8 p.m. Saturday) and "Princess Diana's Death: Mystery Solved" (8 p.m. Sunday). The fact that her tragic passing was even a "mystery" will come as a surprise to most viewers.
