Outside of Demons, I have not see many of Lamberto Bava’s films. A Blade in the Dark has a few really effective and tense sequences. Counter to the title, these horrible killings mostly occur in bright, fluorescent light (not unlike Argento’s Tenebre). Unfortunately, the story is terrible. The victims are just passersby who appear in the main character’s house for no good reason. The hero’s job is that of a horror movie composer. This could have been played up in some real interesting ways but, except for some disjointed voices on his tape early on, it really plays no part in the plot.
