Who Killed the Prosecutor and Why?

A fine looking and well acted giallo that sadly doesn't really have the drive or umph to make it particularly good. It starts off strongly enough, with a photographer witnessing a murder, but then it gets dragged down in a blackmail story that takes an age to get anywhere. Adolfo Celi's cop slows it all down further, and there isn't a whole lot of murder to boot. A nice looking but ultimately hollow view.
