Because she was in love. It's what makes the world go round and in Julie's case makes her oblivious to Jeremy's faults however heinous to another person. Jeremy had become arrogant,he had been questioned by Taff Jones and let go and in Jeremy's mind that was the end of it. The carpets and bedding had been burned at White House Farm and the four murders and a suicide was still the official verdict. Jeremy had money coming to him,he had installed himself in the Maida Vale flat and he had Anji Greaves at the end of a telephone line. Why should he tie himself down at 24 years of age with Julie,when it would be his word against hers in the witness box? Jeremy paid Julie off with £400 and thought that was the end of the affair;he even helped her to move house so there was no animosity involved,just Jeremy at that stage of his life felt a new sense of freedom he had never experienced before with his parents gone and he was going to make the most of it.
Murder is a very serious accusation,and in this case,it was JM who ( not in as many words ) accused him of and had him convicted.Would she still have gone along with her tissue of lies if he hadn't have dropped her for someone else.? Would she still have continued sleeping with the man to whom she visited his nephews in the morgue,that he supposedly shot.? Would she still have been prepared to have married JB and had his children.? Was she so in love that she couldn't envisage more children being shot.?
I'm damn sure that anyone in their right mind, after seeing two dead children,who were supposedly shot by the man you were sleeping with,would have dobbed him in there and then out of sheer fear and not love for the man. How can anyone be in love with someone like that.? Oblivious my eye. It's because he didn't commit any murders and she knows it.
There may not have been animosity on JB's part,,but there certainly was as far as JM was concerned.
If anyone put on an act at the funeral,it was her. Hard as nails.
