Jessica is goaded into looking into a murder that happened 25 years ago. It seems a pop star was filming a variety show when he turned up dead...stabbed to death. Unfortunately, the police at the time were unable to solve the case and someone's gotten the bright idea to have a reunion TV show of the cast of this old variety show. Soon Jessica learns that this dead pop star was anything but an angel and the motivation for the killing is interesting.
The best thing about this episode are the old time stars featured in it, such as Donald O'Connor, Anne Francis, Gavin McLeod and a few others. The case is interesting, though the notion of a reunion show with all the stars of the 1965 one (minus, of course, the dead guy) is a bit farfetched....but it is well worth seeing and fun.
By the way, in an odd job of working against type, Sheldon Leonard does NOT play his usual gangster but a retired cop!!
