Filmed in black and white, Perry Mason has a seductive noir sensibility. Here in sunny California are convoluted cases involving corruption, blackmail, scandal, revenge, and greed. Perry, with the help of private detective Paul Drake (William Hopper), sorts it all out, and in the episode codas, further parses the evidence ("I still don't see what put you on the right track" is a typical query) in inscrutable ways that invite replay. Beyond the pleasure of watching an actor thoroughly embody his character, it's also fun to spot familiar character actors. "The Case of the Petulant Partner" stars Will Wright, who played mean old Ben Weaver on the early seasons of The Andy Griffith Show, and that's a rather fetching Marion "Mrs C." Ross from Happy Days in "The Case of the Romantic Rogue." The episodes crackle with some old-school, hard-boiled dialogue. Almost worth the price of the set is hearing Lt. Tragg make with the beat talk in "The Case of the Jaded Joker." "I'm one of the cool ones," he jokes with Della and Perry. "I don't dig slick chicks trying to goof me up, daddy-o." Once again, this set is guilty of providing no extra features, but we'll let them off with a warning. This time. --Donald Liebenson
