this be a low budget movie and it have it flaw but i like it because of the way it show how loneliness and alienation and a bad upbringing can turn a man from be a quiet introvert into a peeping tom and then a murderer and then full blow insanity . laszlo papa have the unfortunate habit of mumble his line but maybe this be do so to deliberately display the ostracised nature of his character . if so and my apology to mr papa . belle mitchell and who previously have appear in house of frankenstein and the beast with five finger and also star a the landlady of the boarding house where the title character stay .
