Lou Antonio, who always made one heck of a bad guy, returns... this time blackmailing Julie's boyfriend, well played by well meaning Robert Foxworth. Of course, for every action there is a reaction (without giving too much away). What is his secret problem?? Toss in a superior supporting cast, including Billy Dee Williams and Burr DeBenning, playing Dr. Corman, who looks suspicious himself. DeBenning appeared the previous season and always takes center stage with some fine acting. To note, Lou Antonio, the all purpose actor, rose to tv cult status a few years earlier as one of the famous black and white aliens on STAR TREK. Seymour Robbie directed, who was behind many cop shows, such as CANNON. So you know there's lots of action. Case in point, the burning rubber car chase finale. This idea had to be lifted from MANNIX as Peggy Lipton and Foxworth are relentlessly chased through a dark parking garage by a maniac driver behind the wheel of a screeching Dodger Charger. This goes on for awhile and looks to be the same garage Joe Mannix was always chased in. The doors are locked and apparently there is no way to escape, however, there are giant support beams everywhere. You could duck behind one, as an example, and let the creep demolish his car and simply walk away? Still a super watch with a creepy feel. SEASON 4 EPISODE 6 dvd box set.
