This film pre-dates Italian director Ercoli's two "Death Walks..." giallos, currently available in No Shame's DVD box set, and has also been released in a nice widescreen presentation, but sadly it's far inferior to both of them in my opinion. I wouldn't even call it a giallo, just a mystery/thriller.
While out alone one night, young housewife Milou is accosted by a handsome but menacing stranger who tells her he has something planned that will ensure Milou will soon be at his mercy...she escapes him unharmed, but with his chilling words "your husband is a murderer" ringing in her ears. It won't be the last time she hears from him, and what follows is the mildly interesting tale of this mysterious man's campaign of harrassment against Milou, which leads her deeper and deeper into fear and bewilderment. As played by the attractive Dagmar Lassander, Milou makes for a believable and sympathetic heroine, even if she is a bit wet. This is quite important, as, had the character been any less engaging the film would have scarecly kept the viewer's interest going for the full running time. Another plus is the appearance of Ercoli regular Susan Scott as Milou's more worldly friend Dominique, a much more confident woman with a tough attitude and some very colourful past-times (pornography and a variety of casual lovers among them), and as the stalker's attention becomes more fiendish, it's only Dominique who seems capable of keeping Milou the right side of sanity. Less of a plus is the sight of Simon Andreu yet again as the slimy villain...although he's good at this kind of role he never seems to put any extra depth into the often very similar characters he keeps being given to play. Milou's husband is played with no real conviction and an awful comb-over by Pier Paolo Cappoli, but he's very much side-lined by the central three cast members as listed above.
What I really wanted from this film was to be knocked over the head by a complicated and sophisticated plot with some unexpected twists, and a rousing finale to finish it off. If Milou had found herself dragged into a seemingly inescapable situation, but then found the wit and courage to turn the tables on her tormentor, I would have been carried through to the end quite happily, but she doesn't, and the mystery is (finally) solved quite mundanely, with very little flair and no twist revelations - apart from the explanation behind Milou's intimidation, which was not very interesting either.
Once the film was over, I felt as though I had been watching nothing more than 90 minutes of pleasantly moving Italian 1970's wallpaper. There's very little tension or suspense, no set-piece murders (Milou is the only person in peril throughout the film) and no flashy camera work - although I was blown away by one beautifully composed shot of Dagmar Lassander's face framed between two bright red curtains at one point. However thats just one shot! Fans of the Ercoli Death Box Set won't find their expectations met with this film
