this interesting giallo boost a typical but still thrill plot and a really sadistic killer that obviously like to hunt his victim down before murder them in gory way . direct by emilio p. miraglia who and one year earlier and also make the very interesting la notte che evelyn usci della tomba ( see also my comment on that one ) and the film start off a little slow and but all in all and no time be waste with unnecessary sub plot or sequence . this film be a german italian coproduction and but it be release in germany on video only in a version trim by 15 minute of plot under the stupid title horror house . at least the murder scene and which will satisfy every gorehound and be fully intact and and the viewer still get the killer motive at the end . but the italian version contain all the footage be still the one to look for and of course . a convincing giallo with obligatory twist and red herring and la dama rossa uccide sette volta be highly recommend to giallo fan and slightly superior to miraglia above mention other thriller .
