If Julie wanted to be the lady of the manor, you would think she would keep her trap shut. I'm sure Jeremy would have advised her to do this.
Telling one person could be fatal, as that person could go straight to the police. However in between Jeremy whisking her around Europe, Julie had the time and the desire to tell not one, but five people what she knew.
This refutes the suggestion that she was amazingly brave and stupid and charged to the police in a rage, because Bamber had apparently jilted her. Although Bamber asking another woman out in front of her, didn't help him.
She had obviously been in turmoil and thinking about what to do for several days or weeks. Bamber had put the frighteners on her and told her how safe he was and that she wouldn't be believed.
So Julie spoke to Liz Rimmington, Andy Bishop, Karen Bishop, Malcolm Walters and Susan Battersby. These people encouraged her to go to the police. Which she did do.
Telling five people really backed her into a corner. As she would anticipate at least one of these people would approach the police and tell them what Julie knew. Perhaps without realising it, this is what Julie wanted, moral support and being in a situation where she had just one option. Which to her was morally the right option.
If Julie and Bamber were still together when she first started telling people, why did she talk ? Telling people what she knew while her and Bamber were still an item, contradicts the alleged reason she went to the police.
Why do other people believe she told five people before going to the police ?
