In a Milanese night, a masochistic man, Mattia Grandi, is strangled with the hands of a female prostitute in his house, and a middle-aged woman, Laura Falconieri, is killed with a spanner in the empty bus. In each case, the killer leaves a meaningful illustration of the children's book titled PIERINO-PORCOSPINO. And then the Naples-born Lieutenant Lomenzo, who is in charge of these cases, meets an informative model named Jeanne who tells him that there was an accidental sudden-death of a prostitute named Roza Catena at the meeting of a club named WILDLIFE'S FRIENDS in which the two victims participated... I think the whole story of this film is one of the most unique ones of the Gialli in the 1970s'. Indeed the concludingness of its serial murders seems to be too unique even for the serious Giallo lovers to gladly accept. But it is not unexpected one because most of the murders in this film are a little too large-scale to be conventionally concluded. And it should be add that the cool beautifulness of Corinne Clery, who superbly plays the enigmatic model, is highly appropriate for the very mystery this film has. Unfortunately, as a post-TORSO giallo, this film has something problematic; not only Daniele Patucchi's music but also Giovanni Capelli's special effects are definitely weak and almost minimalistic (except for the only one murder sequence which has unusually energetic music. Strangely enough, although most of the murder sequences of this film are disappointingly light, the same one is exceptionally gory, too.) Incidentally, this film has at least two prints. For instance, in the shorter print (and this not-Italian-but-English-speaking one seems to be so-called International Version), the murder sequence of Laura Falconieri is heavily cut, and therefore one can hardly understand what is precisely going on in the problematic bus. Indeed, in the problematic print, the victim is simply murdered without giving notice, and therefore it is no longer a murder sequence; it is rather a murder scene.
