this movie be often consider to be one of bava best and and i can see why some would say that . maybe there something i just do not understand about the movie that make me miss the point . the plot revolve around the murder of an elderly woman and the subsequent inheritance grab that ensue . possibly what be so off put about this film be that character be introduce and and then kill off five minute later . this isn not so much of a whodunit as much a a whokilledwho . and that all the movie be represent there no mystery a to who the killer be and because it everybody and so it just a matter of who be leave at the end . the murder themselves tend to be fairly original and particularly those that befall a precocious batch of horny teen who stumble onto the family estate ( anyone who see friday the 13th will see the inspiration for that movie right here ) . my one real complaint about this movie be the head scratchingly odd end and which really tie thing up rather nicely and but leave a rather questionable taste in your mouth . a must for bava fan and but others may want to avoid .
