Aus den geheimen Polizeiakten einer europäischen Hauptstadt

An early appearance by Camille Keaton gives Tragic Ceremony its main point of interest. It's not as good as What Have You Done to Soalnge?, but her role is substantial enough for fans to check it out.

Probably it ranks as the second-best of her Italian-era appearances. Her icy beauty and blank expression are suited to her largely passive role.

The plot falls into the Old Dark House genre, with four fashionable and well-off young people becoming stranded at a mansion on a stormy night. Sort of like a straight non-musical version of Rocky Horror.

Black magic and other supernatural events follow, with logic going out the window. The supernatural elements keep this from really being considered as classical giallo.

But there is a fair bit of detective work and violent crime, so some people still put under the giallo banner. It's not apparent in the costumes and locations, but the action is supposed to be in the UK as Scotland Yard is mentioned.

Overall, it is a bit of a generic mix of Gothic horror and police motifs that never reaches its full potential.
