Yet another -- and Mr. Symons' own Sherlock Holmes is one Sheridan Haynes who plays that character on a TV series of diminishing viewership. But chop, chop, chop -- three unrelated men are killed and Sherlock. Sheridan announces that he will solve the Karate Killings (which they're not, by the way) and he does so -- as much by chance as good sense. The new Sherlock, one of those hapless patsies for his wife and others, is nice enough, but the anything but ""elementary,"" overconstructed plot goes up in smoke. Not his best.
