I was thinking the other day that Jeremy never claimed that his father did call the police , because he would not have known if he did . But I think the fact that he said he called back and the line was engaged and then the transcripts later might have convinced him it had happened . But even if Neville did not call the police the one call that would prove that Jeremy was innocent is the call from his father to him. If that was on the records somewhere it would prove his innocence .
