Early giallo that predates both Bay of Blood and all of Argento's work. However, it doesn't have much to offer. As it only has a complicated plot-- since there is no actual story to speak of-- and it never adds depth to its characters apart from using them as plot devices. Deadly Inheritance also lacks much suspense or tension, making it not entertaining. It may, however, sport an OK final 20 minutes, but that's it.
