Superior Hitchcock, featuring two of the quirkiest actors on TV—Redfield and Homeier. That opening scene of the two of them sloshing around while the girl is draped suggestively across the chair is pushing the envelope for 50's TV-- so is the premise, for that matter.
Homeier's "motiveless murder" is rather painstakingly set up in victim Betz's home, even though Homeier's cover story (a pollster) seems implausibly complicated. Nonetheless, the half-hour is smoothly directed with some nice touches, such as the amusing elevator scene.
Good, twist ending that I didn't see coming. I suspect that having justice served on screen instead of during Hitch's epilogue was to satisfy nervous censors. However, if you think about it, I don't think the scales of justice are quite balanced by that ending. See if you agree. Anyway, it's an intriguing and well-directed showcase for a couple of fine actors, one that also helped build the series reputation.
