The basic plot concerns a number of killings that seem to be connected to a scientific laboratory. As the mystery deepens, it becomes something more and more interesting to a journalist (Carlo Giordani, played by James Franciscus) and a blind puzzle enthusiast (Franco Arnò, played by Karl Malden). But as they get closer to the truth, they also get themselves targeted by the killer.
Although a bit bloodless compared to what Argento would deliver within the next few years, The Cat O'Nine Tails is a fun murder mystery that is punctuated by death scenes often enough to help the pacing of the film. For fans of this kind of thing, you get everything you could expect from an early 1970s Italian thriller. A handsome lead. Someone with a disability that doesn't stop them from being quite brilliant, yet critically holds them back from solving the mystery any time before the grand finale (of course). Some wonderfully cheesy dialogue, especially in a scene showing the sexual chemistry about to shatter the beaker when James Franciscus is being as forward as he can be with Catherine Spaak. A bit of gratuitous nudity. A ridiculous explanation for the killings, with some enjoyably silly science backing it up. And, of course, the usual equivalence of any deviance from the entrenched hetero-normative standards with the potential to be a dangerous psychopath.
Franciscus is good in his role, all noble intent and twinkly eyes, and Malden does very well as the blind man who ends up becoming an invaluable assistant as the investigation gathers momentum. Spaak is made to start off icy and full of attitude, before thawing out in the company of the lead hunk, and she does fine in her role. Small turns from Aldo Reggiani, Horst Frank, and Carlo Alighiero help to remind you of the many red herrings to be considered as the killer, up until the reveal that we get in the final sequence. And it's also worth mentioning that Cinzia De Carolis is a lot less irritating than she could have been in the role of Lori, the niece of Malden's character, and someone who provides him with one or two essential observations.
Argento is already showing his eye for interesting shot choices (especially extreme close-ups that show an unflinching eye looking at victims), but there's still some way to go before he would have the style and flair that would make his more celebrated outings stand out from the crowd. The best thing here is seeing him hold back, setting up some nice moments of tension with simpler shot choices and camera movement, in line with a plot that is slightly less convoluted than many of his other works.
It may be more for completists than anyone seeking out the cream of the crop, when it comes to either gialli or Argento films, but it's still more worthwhile than many others you could choose, including some from the latter part of Dario's filmography.
