The title of this solid murder mystery from co-writer / director Emilio P. Miraglia deals with a legend surrounding the well-off Wildenbruck family. Every hundred years, the title character will claim seven victims. The current generation of Wildenbrucks consists of sisters played by Barbara Bouchet (as Kitty) and Marina Malfatti (as Franziska). Kitty is a high-fashion photographer whose circle of friends begin to be butchered by a cackling dark haired woman wearing a red cloak. And this woman would seem to be Kitty's long estranged sister Eveline, but Kitty knows that this cannot be the case.
Miraglia is good at storytelling as well as cinematic flair, giving us an engrossing mystery that offers up enough red herrings to keep things interesting. But, just like any good giallo, it delivers plenty of eye candy - of both the cinematic kind and the human female kind - to add to the presentation and make it quite watchable, even if anybody watching figures things out ahead of time. It just barely sort of flirts with the supernatural, with little surreal touches here and there, and is largely grounded in reality...albeit a stylized, sexualized reality. It can also boast a typically lovely Bruno Nicolai soundtrack; casual viewers may not recognize his name, but he deserves to be as well known as Ennio Morricone, one of the major legends of film music (Italian and otherwise).
The acting is good from the cast; there are some very handsome men and some positively gorgeous women among them. Bouchet is an engaging lead, and Ugo Pagliai is her likeable leading man. Marino Mase is excellent as the dedicated police inspector - what giallo would be complete without this sort of stock character? Rudolf Schundler is a delight as the concerned grandfather who gives us some back story, and B movie goddess Sybil Danning can be seen (clothed and unclothed) as a saucy character named Lulu Palm.
The kills are sure to satisfy gore lovers, and if you're an admirer of this genre, you'll be intrigued by the way that Miraglia switches between a traditional Gothic setting (the family castle) and the modern urban environment. One highlight is when a victim is dragged to their death by a car after their jacket gets caught in the car door.
The sixth, and sadly final, directorial outing for Miraglia, who'd been a script supervisor and assistant director for many years; previously he'd done another giallo, the equally lauded "The Night Evelyn Came Out of the Grave".
