"One of you here tonight is a murderer, and I'm going to prove it," Van Dyke announces just before exposing the magician's killer. What's nice about TV mysteries, as opposed to real-life ones, is that the culprit is always "here tonight." Which may be one reason why the Nancy Kerrigan-Tonya Harding story has struck such a chord. Kerrigan's attacker was not, as most people assumed at first, a crazed fan or a random nut. The crime appears to have been -- just like TV! -- an elaborately plotted effort by another skater's camp to eliminate a rival. Any fan of Murder, She Wrote can recognize the motive. And not even Columbo could have cracked the case faster.
