Another gem written by Robert W. Lenski, who had an eye for detail and lots of imagination. Guest star Lee Purcell actually appears in a far different role. Instead of a victim of circumstances, she is armed and dangerous, playing Kathy Cooper, a very sly and deadly jewel thief.
The neat switch here is that this is an inside job, connected to a very wealthy family. The thing that always amazed me about stories similar to this, the more wealth a family accrued, the more greedy the culprits were. And as you will see!
Dabney Coleman, always a welcome addition to any mystery, plays George and popular character actor Eddie Firestone plays Andy. Firestone had to have held a record for tv appearances, he was everywhere in both comedies and dramas. Look for Buddy Ebsen's pretty daughter, Bonnie, who makes another brief appearance on the show, playing Maxie.
By the way.... the Beverly Hills mansion where this is partly filmed at (North Angelo Drive) sold for 65 million dollars in 2021! Director Walter Grauman surprisingly did make a mistake here, according to notes. When Kathy shoots and kills her equally diabolical partner, he drops the glasses he's holding, but when he falls to the floor the drinks are still in his hands!
Watch this for some dynamic acting on the part of Lee Purcell. SEASON 4 EPISODE 12 remastered CBS dvd box set.
