The best part of this episode may be the locations. That Pacific Ocean Park opening is a real grabber and gets repeated at the end. Tod's duties as a Park worker also take him to other interesting and exotic features. Catch too the cutting edge cool jazz at Shelly's Manne-Hole in Hollywood. On the other hand, this is the first episode without Maharis who would subsequently leave the series altogether. I'm guessing that Tod's blue-collar job at the Park was originally written for Maharis, while Tod would be the white-collar realtor. But with Maharis's abrupt departure, Tod, rather awkwardly, gets both jobs.
Anyway, the delectable Susan Oliver gets a lot of screen time as a highly disturbed young woman, Chris, who behaves in wanton fashion, plays word games, and also gives writer Silliphant opportunity to indulge his penchant for philosophical prose. Chris runs a gamut of emotions that Oliver covers quite well. Too bad the actress died relatively young. Bernardi, familiar from the Peter Gunn series, plays a psychiatrist trying to find out what makes Chris tick. The episode's main twist is not hard to spot and sets up an interesting contrast. All in all, however, the entry's most notable for Maharis's absence that would soon become permanent. Too bad, because whatever their personal feelings, the two made a great team.
