Hi,

I’ve had an old movie that I absolutely love fall from memory somehow and I am trying to find out what movie it is so I can get it on DVD if possible. The only thing I remember is that a serial killer who kills entire families was going around audio recording the murders, a writer? (not sure if that’s right) is staying in the house of some of the victims and the killer showed up, they became more acquainted, writer guy thinks it weird the guy is always wearing headphones, at the end of the movie writer guy has the killers cassette player headphones (left behind? I think the killer got away) and hears the murders happening.
