Death Carries a Cane (AKA
Dance Steps on the Edge of a Razor, AKA
The Tormentor ~ 1973)
Italian/Spanish produced giallo, directed by Maurizio Pradeaux, and starring Robert Hoffmann and Nieves Navarro (under her sometimes alias 'Susan Scott').
Kitty (Navarro) is showing her parents around Rome. Whilst visiting one beauty spot she uses the coin-operated telescope. As she does so she inadvertently sees a murder taking place through an apartment window. A figure dressed in black coat, black hat, and black gloves repeatedly stabs a woman. However, before she can see the killer's face, the telescope's time runs out and the picture disappears. By the time she's managed to put another coin in the killer has escaped. Unable to identify exactly where the killing took place, she has difficulty persuading the police as to what she saw - until the woman's body turns up. As the police try to track down the killer more murders occur - their throats all cut with a straight razor. One clue the police find at the crime scenes is the bloody imprint of the tip of a walking cane...
This all sounds like something straight out of Hitchcock. But it doesn't take long before you're reminded you're in giallo-country, where common sense, logic, and believability very much take second place to blood, nudity, and ridiculous plotting!

That said, it's still pretty gripping. It's interesting to see a thriller set in Rome spending more time in the dirty backstreets than amongst the beautiful architecture. The kills are very tensely filmed, and the closeup, detailed throat and body slashings are all very convincing (shame the blood all over the crime scenes looks like the usual giallo 'someone's kicked over a tin of red paint'). Navarro is good, but Hoffmann (as her boyfriend) is on the wooden side - as is George Martin, who plays the police Inspector. There are of course the usual abundant red-herrings (I've never seen a film where so many people walked with a cane), and when the killer is revealed their motivation makes absolutely no sense. By which I don't mean there's a plothole; I mean that the three (I think) sentences given in exposition don't in any way actually explain why they've done it! But if you're watching for coherence you've probably picked the wrong genre. It's certainly not great cinema, but it's an entertaining time-passer. 7/10
