This is an extremely rare, hard to find movie which to be quite honest is no bad thing. The version I viewed was in its native Italian tongue and is, as far as i'm aware, the only way anyone's likely to see it. The film begins with the dockside discovery of a murdered man and woman which starts an investigation undertaken by a cop (Jeff Blynn) whose favourite past-time is eating hard boiled eggs! (well Kojak had his lollipops I guess). A series of seemingly unrelated murders start to occur, two of which are very nasty, so nasty in fact that I couldn't possibly describe them on such a family friendly site such as this. An already cheap and cheerful film is cheapened further by endless scenes of a couple participating in various sex games, all backed by a Berto Pisano score which wouldn't seem out of place in one of your dad's "stag" flicks. Needless to say these sub- plots seem to tie up in the end (well...at least I think they do). The term "giallo", is the Italian word for yellow and these thrillers (BIRD WITH THE CRYSTAL PLUMAGE, BLOOD AND BLACK LACE and WHAT HAVE THEY DONE TO SOLANGE? being amongst other examples of this fascinating and addictive genre) have their origins in the mystery books published years ago in Italy, which were distinguishable by their yellow covers. When all's been said and done, I cant really recommend this sleazy, sordid affair (not that it's readily available anyway!), unless your idea of a nice night in is a showing of Lucio Fulci's equally misogynistic (but more fun) THE NEW YORK RIPPER. Happy hunting.....
