I'm of the opinion that it's unlikely Janice was killed by a hitchhiker or ramdomer(s) in the layby. I say that because if thst were the case you'd still have the mystery of why she was on the road in the first place. Indications are that she intended to stay in London. She'd told friends that was her plan. She'd started a meal, started drinking wine. It was a dark, wet night and according to Google, Clopton Manor was about 80 miles away. The indications in the flat are that she left in a hurry. Half eaten meal, dirty dishes in the sink. And if the Crimewatch reconstruction is accurate her handbag was left on her bed in the bedroom. The contents of which were partially emptied on to the bed. As if she'd tipped them out in order to grab what she wanted in a rush. Everything seems to point to something happening unexpectedly. If she was killed in a random attack then what was the reason she left the flat in a rush and why did no one come forward to say they'd contacted her? They would have had no involvement in the murder after all. Currently I favour the idea she already had someone with her, perhaps whoever it was who may have contacted her in the first place. There's no witnesses to her leaving the flat so we don't know if anyone was with her or if she may have collected someone.
I'm also interested in Tony Weston. He seems quite a vague character. He was married before with children. He'd met Janice through her work. It's said he had various property interests in the UK and abroad. Apart from that there doesn't seem a lot of information on him. He was a property developer/speculator. How successful he was, how he well he was regarded, who he mixed with and so on is unclear. These activities sometimes are undertaken in a somewhat murky world. I think there's been some speculation whether he started an affair with Janice whilst still married or not. The police went in very heavily on him. Extended and intense interrogation. I'd like to know their thinking at the time. It really looks like they thought they had their man. I know he was in France and sone have suggested there was a window of opportunity for him to return and be involved. That to me seems to be stretching it. However it seems to me he was subjected to more than routine enquiries and I wonder why?
When it comes to Janice we know she was successful and ambitious. Tony wasn't the first time she had become close to a client. Something usually frowned upon in professional organisations. We know she had inherited a large amount from an elderly client. A client who had at one stage proposed to her. Not sure to what extent that relationship reached. Exactly how close they were. Usually if a relationship of this sort or the one with Tony arises that person's business affairs would immediately be passed to a different partner in the firm due to the obvious high risk of conflicts of interest arising. Indeed the elderly clients will was challenged by his family. So they weren't happy about it. Could Janice have upset someone along the way? Did someone think Janice had taken advantage of the client perhaps?
