THERE'S A HOMICIDAL maniac loose, which is really The Most Deadly Game. He seems to be killing fashion models, so Vanessa (Yvette Mimeux) is set up as bait — and she's caught. Among the suspects are three ex-series stars — Frank Converse of NYPD; Barbara Hale, of Perry Mason; and Bill Smith, of Laredo. The fashions you'll see were created by Nolan Miller, who does all of Yvette's clothes.
