In 1972, writer-director Aldo Lado made two outstanding giallos, THE SHORT NIGHT OF THE GLASS DOLLS (a.k.a. PARALYZED) and this film, which predates Nicholas Roeg's similar but far more well-known DON'T LOOK NOW (1973).
Young Roberta (Nicoletta Elmi) arrives in Venice from London to visit her father, celebrated sculptor Franco (George Lazenby). Franco's estranged wife, Elizabeth (Anita Strindberg), stays in England. After a few days, as Franco is making love to a girlfriend, Roberta is kidnapped. Soon after, her corpse is found floating in a canal.
Racked with guilt, Franco investigates the crime on his own. His chief suspects include a prominent but ruthless businessman, Serafian (Adolfo Celi), and an attorney with a history of pedophilia (Peter Chantel). He suspects both men know more about Roberta's death than they let on. Meanwhile, though, the killer is always one step ahead of Franco, knocking off everyone who might be inclined to help him.
Lado and co-scenarists Massimo D'Avak and Francesco Barilli add many subtle touches to the rather crude story line. For example, Venice itself becomes a character and conspirator, and is photographed as a nearly colorless and malevolent place. Early in the movie, Franco shows his disrespect for the city, offhandedly remarking that "Venice is a dead city," and wishing it would simply sink into the water. Later, we see that the businessman and attorney, representing the old money and establishment values that run and keep Venice "afloat," conspire to protect the killer and, indirectly, to "punish" Franco.
Not only is Venice viewed as a deeply evil, it twists -- even in small ways -- the people who live there. In the early minutes of WHO SAW HER DIE?, most of the male characters are shown touching or petting Roberta rather inappropriately. In addition, the local constabulary is extremely lame and inactive. When the bodies start to pile up in the wake of Franco's investigation, a detective tells him to let the police handle the dangerous work. Of course, they continue to do nothing but in the end take full credit for catching the killer. This conspiracy of silence extends even to the father of a child who was killed in a manner consistent with the way Roberta was killed. When Franco tries to enlist his help, the father acts suspiciously and refuses to get involved.
The movie's conspiracy subtext extends to two secondary characters, Phillip and Ginevra, who wish to escape Serafian's grip but cannot. In the Venetian universe created by Lado and Co., Ginevra is willing to both help Franco find the killer and expose Serafian as indirectly responsible for Roberta's death. For her trouble, Ginevra is murdered but nonetheless helps Franco get closer to revealing the killer's identity.
In and around these rich contextual elements, the giallo aspects of WHO SAW HER DIE seem rather perfunctory. To be fair, however, there are a couple of well done thrill-for-thrill's-sake stalking sequences, and one creepy moment when Elizabeth, alone in Franco's apartment, is terrified by bumps in the night that are nothing more than a housekeeper doing some chores. And Ennio Morricone's excellent score features a purely musical insight into the killer's tormented mind, a kind of "murderer's refrain" that is punctuated with calls and cries by a chorus of young female voices.
