Yes, so I don't know where Caroline got all that from about her knowing he had 2k in the bank?
if you were paying a hit man I dont think you would be stupid enough to go and draw the money out of your own account straight after the event, don't forget he had been planning for a year so he would have the cash stashed away somewhere so I think this whole argument is nonsense.
The only way I can see Jeremy having said any of the hit man stuff ( although of course he claims it is fabrication) is if Julie had started probing him accusingly and he ( on the verge of dumping her) thought was a silly young woman ( as he was innocent ) and started making sarcastic comments which he never thought she would take seriously.
But I still don't believe innocent or guilty that he said any of it. It just does not make any sense at all.
Especially if the relationship was on the wane you would not want to give anything away to implicate yourself . If he did all that planning , with the phone detail and everything else that was involved , you are not going to risk everything at the last minute.
