Spasmo star Robert Hoffmann has all the charm and charisma of a bowl of soup as male lead of this mediocre entry in the giallo canon. Neives 'Susan Scott' Navarro is her usual feisty, likeable self, but this isn't enough to carry Maurizio Pradeaux's film, which, despite the presence of Navarro and fellow veteran Simon Andreu, is unrelated to Luciano Ercoli's infinitely more satisfying pair of Death Walks... outings.
After Navarro witnesses a bedroom murder through a park telescope, the cane wielding killer works his way through anyone who may be able to finger him, dealing out some rather nasty throat slashings along the way. As is so often the way, said killer turns out to be someone in her immediate social circle. What are the chances of that, eh? Leaden, episodic pacing, lacklustre performances and several interchangeable blondes lead to an ultimately forgettable experience. Some suspense is generated in the last fifteen minutes but by then it's too little, too late.
To be resorted to only when ones stash of Grade A gialli has been well and truly 'caned'.
